Light-sensitive composition consisting essentially of, in admixture a nonionic aromatic diazo compound and a cationic dye/borate anion complex

摘要

A light-sensitive composition is provided comprising (a) an aromatic diazo compound and (b) a cationic dye/borate anion complex. In a preferred embodiment, the cationic dye/anionic borate dye complex is represented by the general formula (I): (I) wherein D+ represents a cationic dye; and R1, R2, R3 and R4, which may be the same or different, each represents an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group, an unsubstituted or substituted aralkyl group, an unsubstituted or substituted alkenyl group, an unsubstituted or substituted alkynyl group, an unsubstituted or substituted alicyclic group, or an unsubstituted or substituted heterocyclic group. The aromatic diazo compound can be a nonionic diazo compound. The light-sensitive compound can further comprise a radical-polymerizable unsaturated compound.
