COATING COMPOSITION

摘要

A coating composition capable of forming an acrylic hard coat film contains (A) an acrylate component and (B) a metal oxide, wherein a mass ratio (B)/(A) of (B) the metal oxide to (A) the acrylate component is from 0.1 to 1.5, (A) the acrylate component comprises components (a-1), (a-2) and (a-3), and a content ratio X of the component (a-1), a content ratio Y of the component (a-2) and a content ratio Z of the component (a-3) satisfies the following conditions (1) and (2). Condition (1): in (A) the acrylate component, X is from 40 to 60% by mass, and a total of Y and Z is from 60 to 40% by mass, and condition (2): in the total of Y and Z, Z is 0% by mass or more and less than 100% by mass.
