Abstract
A paint composition producing paint films which change from an achromatic color to a chromatic color when the angle of incidence of the light with respect to the normal to the paint film plane is changed. The paint composition comprises (A) glitter material which has an angle-dependent interference effect and (B) metal oxide coated mica and/or metal oxide coated alumina flakes in proportions where the content ratio ((A)/(B)) of the (A) component with respect to the (B) component, as the solid fraction mass ratio, is from 2.5/1 to 1/6 and in which the interference color of the (A) component and the interference color of the (B) component at a face angle of the paint film have a complementary color relationship.
