Abstract:
A photosensitive composition which comprises (i) a sensitizing dye represented by formula (I), (ii) an activator compound that generates chemical changes by its interaction with an electronic excitation condition induced by light absorption of the sensitizing dye represented by the formula (I) and thereby produces at least one of radicals, acids and bases and (iii) a compound whose physical or chemical characteristics are changed and maintained by undergoing reaction with at least one of radicals, acids and bases; ##STR52##wherein A represents S atom or NR.sub.7, Y represents a non-metallic atomic group which forms a nitrogen and/or sulfur-containing heterocyclic ring which does not contain a carbonyl carbon as a ring-constituting atom together with the adjacent A and carbon atom, each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 independently represents a monovalent, non-metallic group, and R.sub.7 represents an alkyl group or an aryl group.
