PROBLEM TO BE SOLVED: To provide a polymerizable colorable composition which is radically polymerizable, first causes a polymerization reaction and develops a color by a successive light irradiation, and elutes no dye.SOLUTION: A polymerizable colorable composition contains an azine compound represented by formula (1), and a photopolymerization initiator. In the formula, R, Rand Rare each independently a substituent; X is an oxygen atom, a sulfur atom or NR; Ris a hydrogen atom or a substituent; at least one of R, Rand Ris a radically polymerizable group; and m and n are each an integer of 0 to 4. |
