Abstract:
A photocurable composition comprising at least one of the iodonium salt compounds represented by a general formula (I): wherein R1 and R2 represent each independently hydrogen, optionally-substituted alkyl, optionally-substituted cycloalkyl, optionally-substituted alkoxy, or carboxyl or its ester, a and b represent each independently an integer selected from 1 to 4, provided, when a and/or b is 2 or more, respectively, the corresponding 2 or more substituents, R1 and/or R2, may be the same or different group, respectively,Y represents non-nucleophilic anion residue, A represents any one group selected from a group consisting of substituents represented by the following chemical formulas, B represents optionally-substituted alkylene or optionally-substituted phenylene, i, j and k represent each independently 0 or 1, provided, i, j and k never be 0 at the same time and there is no case for i=1, jâˆ’0 and k=1, simultaneusly, R3, R4, R5, R8, R19 and R29 represent each independently hydrogen, halogen, optionally-substituted alkyl, optionally-substituted cycloalkyl, optionally-substituted phenyl, optionally-substituted alkoxy, optionally-substituted cycloalkoxy, optionally-substituted phenoxy, or carboxyl or its ester, R6, R7, R9, R10, R12, R13, R15, R16, R17, R18, R20, R21, R23, R24, R26, and R27 represent independently hydrogen, optionally-substituted alkyl, optionally-substituted cycloalkyl or optionally-substituted phenyl, c, d, e, f, g and h represent each independently an integer selected from 1 to 5, provided, when c, d, e, f, g and/or h represent 2 or more, respectively, the corresponding 2 or more substituents, R3, R4, R5, R8, R19 and/or R29, may be the same or different group, respectively, n, m, p, q, r, s, t and u represent each independently an integer selected from 1 to 8, provided, when n, m, p, q, r, s, t and/or u is 2 or more, respectively, the corresponding 2 or more substituents, R6, R7, R9, R10, R12, R13, R15, R16, R17, R18, R20, R21, R24, R26 and R27, may be the same or different group, R11, R14, R25 and R28 represent each independently hydrogen, optionally-substituted alkyl, optionally-substituted cycloalkyl or optionally-substituted phenyl, R22 represents hydrogen, optionally-substituted alkyl, optionally-substituted cycloalkyl, optionally-substituted phenyl or optionally-substituted alkoxy, v and w represent each independently an integer of 0, 1 or 2, and X represents halogeno, a cationically polymerizable compound, and a sensitizer.
