WIPO Patent Application WO/2021/132246

A1

Provided is a coating composition capable of forming a coating film which is thin and, despite this, can hide the color of the coated object and which is excellent in terms of adhesion, chemical resistance, water resistance, flexing characteristics, and appearance.　This coating composition includes at least one ingredient selected from among a maleic-anhydride-modified polyolefin resin (A), a glycidyl-group-containing acrylic resin emulsion (B), and a urethane resin dispersion (C) and further includes a resin dispersion (D) and a hardener (E), wherein the (A), (B), and (C) have solubility parameter SP values that satisfy a given relationship. In cases when a mixture comprising the at least one ingredient, the (D), and the (E) in the same mass proportions as in the coating composition is applied to form a coating film having a thickness of 30 μm, the coating film has a haze of 30% or higher.
