AQUEOUS FINISHING ONE-COAT PAINT COMPOSITION AND FILM FORMING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an aqueous finishing one-coat paint composition capable of forming a coated film with favorable recoat adhesive property, water-, weather- and chipping-resistance, and a method for forming a coated film using the same.;SOLUTION: The aqueous film forming one-coat composition contains (A) a polyester resin with an acid value of 10-70 mgKOH/g, a hydroxy group value of 70-170 mgKOH/g and a benzene ring concentration of 1.25 mol/kg or less (solid resin component), (B) a curing agent, (C) a coloring pigment and (D) a pigment-dispersing acrylic resin prepared by copolymerization of a monomer mixture comprising (a) a polymerizable unsaturated monomer containing at least one ionic functional group selected from the group consisting of a tertiary amino group, a quaternary ammonium base and a sulfonic acid group, (b) a non-ionic polymerizable unsaturated monomer having a polyoxyalkylene chain, and (c) another ethylenic unsaturated monomer, in the presence of a radical polymerization initiator.;COPYRIGHT: (C)2004,JPO
