Coating compositions whose perceived colour depends on the angle from which they are viewed and the use of such compositions in base paints for multiple layer paint coatings

Abstract From the Canadian patent

Coating compositions are disclosed, suitable for use as base paints for multiple layer coatings whose perceived colour depends on, the angle from which they are viewed. They contain: one or more binders usually used in such coatings; one or more scale-type pigments the hue of which depends on the angle from which they are viewed these pigments consisting of oriented, three-dimensionally cross-linked substances of chiral phase, liquid crystalline structure; one or more usual effect pigments which differ from the said scale-type pigments; optionally one or more cross-linking agents; optionally one or more colour-imparting absorption pigments and/or fillers; and optionally additives usually …
