PROBLEM TO BE SOLVED: To provide a radiation-sensitive composition that can form a cured film that is excellent in definition and sensibility, and has high image development resistance, heat resistance, solvent resistance or the like.SOLUTION: A radiation-sensitive composition includes: [A] a polymerizable compound having an ethylenically unsaturated bond; and [B] a photoinitiator represented by the following formula (1). In the following formula (1), Rrepresents a morpholino group, a piperidino group, a dimethylamino group or a diethylamino group; Rand Rrepresent each independently a 1-6C alkyl group; Rand Rrepresent each independently a hydroxy group, a methylol group or a 1-6C alkyl group; n represents an integer of 0-6; and X represents an oxygen atom or a sulfur atom. Moreover. the radiation-sensitive composition preferably includes [C] an alkali-soluble resin further. Further, the radiation-sensitive composition preferably includes [D] a colorant further. |
