Abstract: Disclosed is a method for the formation of multi-layer paint films with the omission of a mid-coat paint coating process. The method comprises the use of a particular aqueous colored paint (A) comprising a prescribed amount of specified titanium oxide that has been compounded, The resulting multi-layer paint films have a very bright paint color, and especially a white or light-colored color, and have excellent concealing properties. The aqueous colored paint (A) is characterized by containing from 50 to 60 mass % with respect to the whole paint solid fraction of titanium oxide of specific surface area not more than 13 m2/g.

Abstract: To provide a waterborne mid-coat paint composition for obtaining paint films which have an outstanding painting performance (particularly in terms of sagging resistance) and are smooth and give a high- quality appearance. [Solution Means] A waterborne mid-coat paint composition which contains, as indispensible components, (A) a water-soluble or water-dispersible polyester resin, (B) a melamine resin, and (C) polypropylene glycol, where said component (A) is a polyester resin which has been rendered waterborne by adding 7-20 mass%, based on the resin solids content of component (A), of (a) a C1-3 alkoxy group-containing glycol monoalkyl ether to a polyester resin of resin acid value 25-35 mgKOH/g and then neutralizing with a secondary amine and/or tertiary amine, and said component (B) comprises a methylated melamine resin and a methyl/butyl mixed alkylated melamine resin, and the content ratio based on resin solids content by mass of the methylated melamine resin to the methyl/butyl mixed alkylated melamine resin is from 50/50 to 90/10, and the content ratio based on resin solids content by mass of component (A) to component (B) is from 70/30 to 90/10, and said component (C) has a number average molecular weight of between 400 and 1,200, and the content of component (C) by mass percentage is between 1 and 10 mass% in terms of the combined resin solids contents by mass of component (A) and component (B).
