Beschreibung
Zusammenfassung:	A photocurable composition comprising (A) 100 parts by weight of a compound having an ethylenically unsaturated group, (B) from 0.001 to 5 parts by weight of a cationic dye having an absorption maximum wavelength in the wavelength region of from 400 to 1,200 nm represented by formula (1): wherein D represents a cation having an absorption maximum wavelength in the wavelength region of from 400 to 1,200 nm, and A1 represents an anion, and (C) from 0.005 to 10 parts by weight of a quaternary borate-type compound represented by formula (2): wherein R1, R2, R3 and R4 each independently represents an alkyl group, an aryl group, an aralkyl group, an alkenyl group, an alkynyl group, a silyl group, a heterocyclic group or a halogen atom, and Z represents a cation, wherein from 5 to 95 wt% of (A) the compound having an ethylenically unsaturated group is a urethane (meth)acrylate oligomer obtained by the reaction of a polyisocyanate having three or more isocyanate groups within one molecule with a hydroxyl group-containing (meth)acrylic acid ester.
