<p><P>PROBLEM TO BE SOLVED: To provide a polymerizable color-developable composition, which is radical polymerizable, which first induces a polymerization reaction, then develops a color by followed and subsequent irradiation with light, and which causes no elution of a dye. <P>SOLUTION: The polymerizable color-developable composition contains a xanthene compound expressed by formula (1) and a photopolymerization initiator. In the formula, R1 to R3 each represent a substituent; R4 to R7 each represent a hydrogen atom, alkyl group, aralkyl group, aryl group or radical polymerizable group, provided that at least one in R1 to R7 is a radical polymerizable group; m and n each represent an integer of 0 to 3; and l represents an integer of 0 to 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
