Provided is a transparent photosensitive composition, which uses an initiator having an oxime ester group and a triazine groups in one molecule, absorbs UV rays efficiently, and shows excellent sensitivity, residual film ratio, mechanical strength, heat resistance, chemical resistance and developing resistance. The transparent photosensitive composition comprises: (a) a triazine-based photoactive compound containing an oxime ester group represented by the following formula(1); (b) a polymerizable compound having ethylenically unsaturated bonds; (c) an alkali soluble resin binder; and (d) a solvent. In formula(1), n is 1 or 2; when n is 1, R is a substituted or non-substituted alkyl, substituted or non-substituted phenyl or alkyl carboxylic acid, and L is H or an alkyl; when n is 2, R is alkylene, phenylene or a specific divalent radical; R' is H, an alkyl, nitrile or phenyl; and X is a substituted or non-substituted arylene, substituted or non-substituted divalent heterocyclic group or a compound represented by the following formula(2). In formula(2), each of Z and Z' is CH2, O, S or CH=CH, wherein R" is H or an alkyl; each of l and m is an integer of 0-2 with the proviso that l+m is not o; A is a single bond, CpH2p, O(CH_2O)p, CH=CH, NR"', S, O, S=O, SO2 or C=O, wherein p is an integer of 1-6, and R"' is H or an alkyl, with the proviso that when l+m=1, A is not a single bond; and each of Y and Y' is H, a halogen atom, CN, alkyl, alkoxy, alkylthio or morpholino. |
