There is disclosed a process to form metallic multilayer coating films characterized by coating on the uncured coating surface of a paint formed on a substrate with a composition (B), which contains non-leafing aluminum flake and organic solvent and then by coating, optionally after coating with a topcoat paint (C), with a clear paint (D). According to said process metallic multilayer coating films, which is white, excellent in metallic luster impression and having a high flip-flop effect, can be formed by using non-leafing aluminum flake pigment.

Metallic multilayer coating films formation process

There is disclosed a novel organic solvent type coating composition capable of making the solid content concentration at the time of coating to higher than 70% by weight, without lowering the properties, which urethane type coating materials have, such as acid resistance, scratch resistance, finishing appearance etc. The composition comprises (A) a vinyl type polymer having both hydroxyl groups and alkoxysilyl groups in the molecule and having a number-average molecular weight in a range of 2,000 to 10,000; (B) a polyol compound having a number-average molecular weight of less than 1,000 and having a hydroxyl value in a range of 120 to 1,000 mgKOH/g; (C) a polyisocyanate compound having a number-average molecular weight of less than 2,000; and (D) a silanol group forming catalyst.

Coating composition

An organic solvent-based heat-curable high solid coating composition comprising:
