PURPOSE:To obtain the titled composition having a high sensitivity by incorporating a specified aqueous s-triazine compd. in the titled composition, thereby incorporating a free radical forming agent having a high sensitivity against photolysis in the titled composition. CONSTITUTION:The titled composition contains the aqueous and photosensitive s-triazine compd. shown by the formula wherein R1 is carboxylate or sulfonate group, etc., or alkyl, a substd. alkyl or a substd. amino group, etc. having said groups, R2 and R3 are each hydrogen atom or alkyl or a substd. amino group, etc., or a group shown by the group R1 which may be the same or the different with each other, X and Y are each chlorine or bromine atom which may be the same or the different with each other, (m) and (n) are each 0, 1 or 2. Thus, the titled composition having the high free radical forming ability and the high sensitivity is obtd. |
