Abstract:
A photopolymerizable composition comprising:i) at least one polyurethane resin binder comprising a) at least one diisocyanate compound, b) at least one diol compound selected from the group consisting of polyether diol compound, polyester diol compound and polycarbonate diol compound, and c) at least one carboxylic acid-containing diol compound, ii) at least one compound having at least four addition polymerizable ethylenically unsaturated bonds and at least two urethane structures, and iii) at least one photopolymerization initiation system containing at least one titanocene compound, and iv) at least one sensitizing dye represented by the formula (A-1) or (A-13) wherein R9 to R13 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an alkenyl group, a substituted alkenyl group, a hydroxyl group, a substituted oxy group, a mercapto group, a substituted thio group, an amino group, a substituted amino group, a substituted carbonyl group, a sulfo group, a sulfonato group, a substituted sulfinyl group, a substituted sulfonyl group, a phosphono group, a substituted phosphono group, a phosphonato group, a substituted phosphonato group, a cyano group, a nitro group or a silyl group, and R9 and R10 or R11 and R12 may form a ring comprising a nonmetallic atom together with the carbon atoms to which R9 and R10 or R11 and R12 are bonded; R14 and R15 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an alkenyl group, a substituted alkenyl group, a hydroxyl group, a substituted oxy group, a mercapto group, a substituted thio group, an amino group, a substituted amino group, a substituted carbonyl group, a sulfo group, a sulfonato group, a substituted sulfinyl group, a substituted sulfonyl group, a phosphono group, a substituted phosphono group, a phosphonato group, a substituted phosphonato group, a cyano group, a nitro group, a silyl group or a heterocyclic group, and R13 and R14 or R14 and R15 may form a ring comprising a nonmetallic atom together with the carbon atoms to which R13 and R14 or R14 and R15 are bonded; and X1 and X2 each represents a cyano group or a substituted carbonyl group, and X1 and X2 may be combined to each other to form a ring; wherein R22 and R23 each independently represents a hydrogen atom, an alkyl group, a substituted alkyl group, an alkoxycarbonyl group, an aryl group, a substituted aryl group or an aralkyl group, A11 represents an oxygen atom, a sulfur atom, a selenium atom, a tellurium atom, an alkyl- or aryl-substituted nitrogen atom or a dialkyl-substituted carbon atom, X10 represents a nonmetallic atom group necessary for forming a 5-membered nitrogen-containing heterocyclic ring, Y11 represents a substituted phenyl group, an unsubstituted or substituted polynuclear aromatic hydro-carbon group or an unsubstituted or substituted hetero-aromatic ring, Z11 represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, an aralkyl group, an alkoxy group, an alkylthio group, an arylthio group, a substituted amino group, an acyl group or an alkoxycarbonyl group, and Z11 and Y11 may be combined with each other to form a ring.
