A photohardenable composition comprising a free radical addition polymerizable or crosslinkable compound, an ionic dye/reactive counter ion complex capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of the polymerizable or cr
A photohardenable composition comprising a free radical addition polymerizable or crosslinkable compound, an ionic dye/reactive counter ion complex capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of the polymerizable or crosslinkable compound, and a disulfide represented by the structure [Figure] wherein X is selected from the group consisting of S and O except in a specific case in which the disulfide is derived from one or more tetrazolyl groups; n represents 0 or 1; A represents the residue of the ring containing the N, C and X atoms, the ring containing five or six members and, in addition, said ring members may be fused to an aromatic ring; and R5 is an aromatic radical selected from the group consisting of (i) phenyl, (ii) benzothiazolyl, (iii) benzoxazolyl, (iv) tetrazolyl, (v) pyridinyl, (vi) pyrimidinyl, (vii) thiazolyl, (viii) oxazolyl, (ix) quinazolinyl, and (x) thiadiazolyl, each of which may have a substituent on one or more C or N atoms of the ring.

A photohardenable composition comprising a free radical addition polymerizable or crosslinkable compound, a disulfide, and an ionic dye/reactive counter ion complex capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of said polymerizable or crosslinkable compound, said disulfide represented by the structure [Figure] (IIa) wherein n represents 0 or 1; X represents S or O; R2 is selected from the group consisting of R1－S－, C1-C20 alkyl sulfido, C1-C20 alkyl, C5-C12 cycloalkyl, －SH and H; and R1 represents an aromatic radicals having 5 or 6 ring members, and in addition may be fused to an aromatic ring. A photohardenable composition consisting essentially of a free radical addition polymerizable or crosslinkable compound, a disulfide, and an ionic dye/reactive counter ion complex capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of said polymerizable or crosslinkable compound, said disulfide being represented by the structure: [Figure] wherein R15 represents an aromatic radical and R4 is selected from the group consisting of C1-C20 alkyl, C5-C12 cycloalkyl, C7-C20 aralkyl, phenyl, naphthyl, mono or dihalogenated phenyl, mono or dihalogenated naphthyl, C2-C20 dialkylaminophenyl, and C2-C20 dialkylaminoaphthyl. A photohardenable composition consisting essentially of a free radical addition polymerizable or crosslinkable compound, a disulfide, and an ionic dye/reactive counter ion complex capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of the polymerizable or crosslinkable compound, said disulfide represented by the structure: [Figure] wherein X is selected from the group consisting of S and O; n represents 0 or 1; A represents the residue of the ring containing the N, C and X atoms, the ring containing five or six members and, in addition, said ring members may be fused to an aromatic ring; and R5 is an aromatic radical selected from the group consisting of (i) phenyl, (ii) benzothiazolyl, (iii) benzoxazolyl, (iv) tetrazolyl, (v) pyridinyl, (vi) pyrimidinyl, (vii) thiazolyl, (viii) oxazolyl, (ix) quinazolinyl, and (x) thiadiazolyl, each of which may have a substituent on one or more C or N atoms of the ring.
