(57) [Summary] [Objective] To obtain a photo- and thermal-decomposition type radical generator that generates radicals with high efficiency by light and heat. [Structure] General formula: (In the formula, R 1 is a tertiary alkyl group having 4 to 10 carbon atoms or a tertiary aralkyl group having 9 to 12 carbon atoms, and R 2 is 1 to 3 carbon atoms. 4 is an alkylene group, R 3 is an alkyl group having 1 to 2 carbon atoms, and m and n are each an integer of 0 to 2 such that m + n is an integer of 1 to 4. ), A novel peroxyketal having a benzophenone group in the molecule and a photo- and heat-decomposable radical generator containing the same. |
