Title: COPPER PHTHALOCYANINE REACTIVE DYES AND COLOR RESIST COMPOSITES FOR LIQUID CRYSTAL DISPLAY CONTAINING THE SAME
Abstract:
The present invention provides reactive phthalocyanine dyes of Formula I: wherein R is a monovalent hydrocarbon chain that has a total of from 4 to 64 carbon atoms and R contains at least one ethylenically unsaturated acrylic ester group or methacrylic ester group, as well as one of a second ester group, an amide or carbamoyl group, and, still further, one or more hydroxyl or OR' groups in which R' can be any of a C1-C12 alkyl group, an allyl group, an epoxy group, a carboxylic acid group, a urethane group (NCOOR), or an ethylenically unsaturated group; wherein M represents divalent metal ion, such as Cu2+; and, wherein, n is 1 to 16. Also provided are films and color resists for blue color filters containing the reactive dye.
