Coating compositions whose observed color depends on the viewing angle and the use of said coating compositions in basecoats for multicoat paint systems

摘要

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 used in coatings of this type.
