Phthalocyanine ink-jet dyes

Mono-azo dyes and inks for ink-jet printing

Disazodyes for ink jet printing

A process for preparing an optical filter comprising a colored cross-linked polymeric coating on a transparent substrate, which comprises applying to the substrate, by a printing process, a mixture comprising one or more polymer precursor(s), and one or more dye(s) having one or more heterocyclic NH group(s) or one or more substituent (s) capable of forming a covalent bond with the polymeric precursor, and thereafter using the mixture. The invention also provides formulations comprising one or more polymer precursors and dyes, optical filters, and a novel dye.
