PHENYLAZO-ACETOACETANILIDE DERIVATIVES WITH A POLYMER! ZABLE FUNCTIONAL GROUP AND RELATED COMPOUNDS AS MONOMERS FOR PREPARING POLYMERIC PIGMENT DISPERSANTS FOR INKJET INKS

摘要

A monomer with a chromophore group represented by Formula (I): wherein AR1 represents a substituted or unsubstituted aromatic group; AR2 represents a substituted or unsubstituted aromatic group or a substituted or unsubstituted alkyl group; and R represents a substituted or unsubstituted alkyl group, with the proviso that one of R, AR1, and AR2 has a substituent with a polymerizable functional group. The monomer can be advantageously used to prepare polymeric dispersants for pigment dispersion, especially inkjet inks.
