Abstract
A photosensitive composition for short wave exposure use, which comprises (i) a sensitizing dye as a 1,3-dihydro-1-oxo-2H-indene derivative having a specified structure, (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 formula (I) and thereby produces at least any 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.
