Japanese Patent JP2664020
Kind Code:
B2
Abstract:
Pigments (I) of laminar structure with a thickness of 1-20 microns are claimed, contg. oriented crosslinked liq crystalline (LC) substances with a chiral phase (II). Also claimed are compsns (III) contg (I) and data carriers contg (I). Also claimed is a process for the prodn of (I), by orienting (II) (opt. after adding other pigments and/or dyes), crosslinking to a 3-dimensional structure and pulverising to the required particles size. Also claimed is a process for the prodn. of compsns. (III), by incorporating pigments (I) into suitable compsns (see below) by conventional methods and then orienting the pigment by the application of shear forces.
