Abstract: This invention discloses a coating method of plastic molded articles, which can form multilayer coating film composed of three layers of water-based primer, water-based base paint and clear paint, the film excelling in adherability to plastic molded articles, water resistance and durability, even when low-temperature baking at not higher than 100° C. is carried out in 3-coat-1-bake system.

Abstract: The present invention provides a process of a forming multilayer coating film characterized by that in a process of forming a multilayer coating film by successively coating with an undercoat paint (A), an intermediate paint (B) and a topcoat paint (C) on a substrate, (1) to use a liquid thermocurable paint containing 0.1-30 parts by weight of aluminium powder and 1-200 parts by weight of titanium oxide pigment per 100 parts by weight of a thermosetting resin composition and the hiding film thickness of its coating film being less than 25 &mgr;m as said intermediate paint (B), (2) to use a solid color paint, a metallic paint or an interference pattern paint as said topcoat paint (C), and (3) to coat said topcoat paint (C) after curing by heating of the coating film of said intermediate paint (B). By this process it is possible to make an intermediate coating film thinner and to form a multilayer coating film with excellent smoothness.

Abstract: A curable top coating composition essentially including(A) a hydroxyl-containing vinyl type resin containing 45 to 55% by weight of styrene monomer as a copolymerized unit of the resin,(B) at least one member selected from among amino resins and (blocked) polyisocyanate compounds, and(C) a microparticulate polymer having an average particle diameter within the range of 0.01 to 1 .mu.m and containing 40 to 60% by weight of styrene monomer as a copolymerized component of each particle,wherein the cured film from the coating composition contains the styrene-derived benzene ring in a proportion of 13 to 40% by weight of the total resin solids;a coating method using the above coating composition, anda coated article obtainable by using the above coating composition.

Abstract: Disclosed is a coating composition for metal coating, said coating composition containing (A) at least one of an epoxidized polybutadiene resin and an epoxy group-containing polyhydric phenol-modified epoxidized polybutadiene resin, and (B) at least one of a capped epoxy resin and a methylol group-containing capped epoxy resin.
