AQUEOUS COATING COMPOSITION AND METHOD FOR FORMING MULTILAYERED COATING FILM

WIPO Patent Application WO/2018/135209

A1

Provided are: an aqueous coating composition which is capable of giving coating films having excellent chipping resistance without lowering the finish; and a method for forming a multilayered coating film. The aqueous coating composition comprises an acrylic-modified polyester resin (A) comprising an acrylic moiety and a polyester moiety, a crosslinking agent (B), and an epoxy phosphoric acid ester compound (C), wherein the acrylic-modified polyester resin (A) contains a polyoxyalkylene-group-containing unsaturated monomer having a weight-average molecular weight of 400 or higher as a monomer component of the acrylic moiety and the polyester moiety is configured of components, 50 mass% or more of which is accounted for by a C6 or higher compound, the content of the epoxy phosphoric acid ester compound (C) being 0.1-10 parts by mass per 100 parts by mass of the sum of the solid components of (A) and (B).

JPH083020	[Title of Invention] Aqueous acrylic-polyester graft resin composition and a coating agent or ink using the same.
JP6512083	Leather coating agent and leather on which the coating agent is formed
JP2002544347	[Title of Invention] Antimicrobial Copolymer
