<p>PURPOSE:To enable the prepn. of the pigment compsn. having various spectral characteristics by arbitrarily combining >=2 kinds of pigments. CONSTITUTION:The compsn. consisting of org. high polymers and org. pigments are the solid solns. of >=2 kinds of the pigments. Further, the org. high polymers are the photosensitive resins consisting of a photopolymerizable compd. having at least >=1 ethylenic unsatd. double bonds and a photopolymn. initiator and other resins in some cases. The more specific examples of the pigments to be used include a perylene pigment, quinacridone pigment, anthraquinone pigment, monoazo pigment, disazo pigment, etc. The org. high polymers to be used include an epoxy resin, melamine resin, acrylic resin, polyimide resin and a polyamic acid resin, polyester resin, etc., which are the precursors thereof. The pigment compsn. obtd. in such a manner has excellent dispersion stability and therefore, the chance in transmittance and depolarizating rate by resting are small and the dispersion stability and spectral characteristics are improved.</p> |
