Acceptable aerosol dispensed paint compositions must have sufficient mechanical stability to withstand the mechanical shearing forces which aerosol water based paint compositions normally experience as they are dispensed from conventional aerosol containers. Insufficient stability results in mechanical shearing of polymeric components of the composition. hand-painted oil paintings Agglomerated bits of the composition can clog the narrow orifices of the aerosol valve outlet and interfere with the even dispersement of paint. Agglomerated bits can also break away from the orifice and be delivered onto the surface of the substrate being painted, thereby marring the paint film thereon.
Mechanical stability of paint formulations has depended in large measure upon maintaining a solution of the polymer in the aerosolized formulation. Proper mechanical stability and low viscosity have been achieved in solvent based systems employing hydrocarbons, alcohols and other solvents. The volatility of the solvent causes rapid thickening of the paint as the aerosolized composition is dispensed and applied to a substrate. Oil Paintings The rapid thickening of the aerosol paint during and after it is dispensed is essential to commercial solvent based paint formulations which must be capable of adhering to vertical surfaces without running.
That property of a paint composition is referred to herein as vertical cling.
Although organic solvent based systems have been developed which have good mechanical stability and vertical cling properties, the solvents employed in such systems are flammable, toxic and environmentally undesirable. Thus, it was deemed desirable to develop a water based paint composition which would possess the degree of mechanical stability necessary for it to be dispensed with a minimum of breakup from a conventional aerosol valve, while at the same time possessing a high degree of vertical cling when the composition is sprayed onto a vertical substrate.

When such prior art airless paint spray equipment is presently used with a painting system
The drive to the piston may take many forms from use of an oscillating crank to the use of a wobble plate as shown in U.S. Pat. No. Re. 29,055 to Wagner, to the use of an eccentric cam wheel drive such as shown in U.S. Pat. Nos. 3,430,557 and 3,623,661 to Wagner, discount oil paintings or other oscillating type connections. Common to all drive connections is the imparting of a reciprocating movement to the hydraulic column drive piston. Normally the drive connection is contained within a housing which forms an oil reservoir for the driving fluid with the cylinder in which the piston reciprocates being provided in a bore through an outside wall of the housing. Such a construction is shown in my prior U.S. Pat. No. 4,022,381 which utilizes an eccentric cam wheel drive.
When such prior art airless paint spray equipment is presently used with a painting system requiring the use of an additional gas source, such as for air surround painting, it is necessary to provide a separate compressed air supply. Since such prior airless paint spray equipment has a distinct advantage of ease of mobility, Oil Paintings airless paint spraying has found wide-spread use in locations where compressed air is not readily obtained. Thus, to use spraying techniques calling for both airless spray painting and air supply, it has heretofor been necessary to bring to the painting site additional equipment for supplying the compressed air.
This can lead to difficulties where the high pressure paint is utilized at a remote spray gun which also utilizes the air. In such situations two separate pressure lines must be provided to the remote gun. To the extent that these two pressure lines originate at different mechanisms, i.e. the paint pump and the air compressor, line entanglement, difficulty in ease of repositioning of the equipment and other disadvantages will occur. It would therefore be an advance in the art to provide a single pumping device which provides separate pressurized liquid and gas streams from a common drive. It would be a further advance in the art if such equipment could be used either for the simultaneous supply of liquid and gas or for the individual supply of liquid or gas.

Staining of the paint film
In such a protective sheet, the weathering stabilizer HMS is included in the layer B disposed on a back side of the substrate , but either is not included in the layer A disposed on the PSA layer side of the substrate or is included in an amount which is one-half or less the amount of HMS in the layer B. By arranging the weathering stabilizer HMS so as to be present in a greater amount on the side away from the PSA layer , hand-painted oil painting it is possible to reduce the amount of HMS present on the PSA layer side surface of the substrate while allowing an amount of HMS sufficient for obtaining the desired weathering resistance to be present in the substrate as a whole.
Staining of the paint film due to the migration of HMS on the substrate surface to the PSA layer can thus be prevented or minimized. Also, because the weathering stabilizer HMS has a relatively large weight-average molecular weight Mw of at least 1.5×103, portrait oil paintings unlike lower molecular-weight organic weathering stabilizers, the HMS in the layer B does not readily diffuse into the layer A. It is thus possible to stably maintain a low HMS content state at the PSA layer side surface of the substrate. For example, even in a mode of use involving exposure to elevated temperatures after the protective sheet has been affixed, an increase in the amount of HMS present at the PSA layer side surface on account of HMS diffusion into the layer B can be suppressed.
Moreover, disposing the weathering stabilizer HMS so as to be present in a greater amount on the outside of the protective sheet is useful also for increasing the HMS utilization efficiency. Therefore, it is possible with the protective sheet of the invention to both achieve a high weather resistance and minimize staining of the paint film. Preferred use may be made of, for example, discount oil paintings a hindered amine-type light stabilizer which satisfies the Mw as the weathering stabilizer HMS. Hindered amine-type light stabilizers exhibit a high weathering resistance enhancing effect, but in conventional methods of use have tended to give rise to staining of the paint film. In the present invention as constituted above, by disposing a HALS which satisfies the above weight-average molecular weight Mw condition so as to be present in a greater amount on the back side of the substrate, a protective sheet which has a high weather resistance and also minimizes staining of the paint film can be achieved.

However, according to the process of the present invention, in another preferable embodiment, the metallic paint film, coated and dried as above, can be coated with a thermosetting resin-type clear topcoating without being baked and in the unhardened state . Oil Paintings As a thermosetting resin-type clear topcoating for use in the formation of a paint film by the 2C-1B process, a thermosetting acrylic-type resin is generally preferable and the ones belonging to a type containing a combination of a conventional functional acrylic-type copolymer and a crosslinking agent, which have a good adhesive force, to a metallic base paint film and a good weatherability can be optionally selected from various types of conventional clear topcoatings without any particular limitations.
There is preferably used a clear paint consisting of an acrylic resin containing units derived from hydroxyl functional acrylic-type monomers in the polymeric chain with the abovementioned amino resin-type across-linking agents, such as butylated melamine-formaldehyde resins or methylated melamine-formaldehyde resins.
The clear topcoating usable in the process of the present invention is prepared by dissolving the above acrylic resin and crosslinking agent in an organic solvent, for example, alkylbenzene derivatives such as benzene, toluene and xylene, alcoholic solvents, such as n-butanol and isobutanol, acetate ester-type solvent such as butyl acetate, ethyl acetate, Cellosolve acetate and butyl Cellosolve, ketone solvents, such as acetone and methyl ethyl ketone and petroleum mixed solvents, such as "Swasol No. 1000" of Maruzen Oil Co. Ltd. in a concentration in which viscosity suitable for coating is obtained. Of course, at that time, in said clear paint can be blended paint components usually added in preparing a clear topcoating, eg, a painted surface adjustor, such as silicone oil.
