Claim 1
Independent Claim
37 words
A photosensitive composition comprising a trihalomethyl-s-triazine compound and a photosensitizer, wherein the photosensitizer is selected from the group consisting of cyanine dyes containing an oxocarbon-bridged nucleus in the methine chain thereof, quaternized acridine dyes, and sulfonocoumarine dyes.
Claim 2
Dependent Claim
37 words
A photosensitive composition comprising a trihalomethyl-s-triazine compound and a photosensitizer, wherein the photosensitizer is selected from the group consisting of cyanine dyes containing an oxocarbon-bridged nucleus in the methine chain thereof, quaternized acridine dyes, and sulfonocoumarine dyes.
Claim 3
Dependent Claim
47 words
A photopolymerizable composition comprising a trihalomethyl-s-triazine compound, a photosensitizer, and a polymerizable compound having at least one ethylenically unsaturated group, wherein said photosensitizer is selected from the group consisting of cyanine dyes containing an oxocarbon-bridged nucleus in the methine chain thereof, quaternized acridine dyes, and sulfonocoumarine dyes.
Claim 4
Dependent Claim
47 words
A photopolymerizable composition comprising a trihalomethyl-s-triazine compound, a photosensitizer, and a polymerizable compound having at least one ethylenically unsaturated group, wherein said photosensitizer is selected from the group consisting of cyanine dyes containing an oxocarbon-bridged nucleus in the methine chain thereof, quaternized acridine dyes, and sulfonocoumarine dyes.
Claim 5
Dependent Claim
28 words
The photosensitive composition as in claim 1, wherein said photosensitizer has a reduction potential not more than 0.10 volt higher than the reduction potential of said trihalomethyl-s-triazine compound.
Claim 6
Dependent Claim
