the metallic paint film

According to one embodiment of the process of this invention, the metallic dry paint film thus formed, can be directly baked by a method, which will be described later on, and thereby can be formed a metallic paint film glossy, smooth, which is crack-and peel-resistant, and excellent in physical properties such as resistance to chemicals, water and weather by employing a 1C-1B process.

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.
