PROBLEM TO BE SOLVED: To provide radical polymerization sensitizers that activate α- hydroxyalkylphenone based or benzylmethylketal based radical polymerization initiators which are active to an energy ray containing light having wavelength of 375 nm to 420 nm and consist only of carbon atoms, hydrogen atoms and oxygen atoms.SOLUTION: The radical polymerization sensitizers contain 9,10-bis(substituted carbonyloxy) anthracene compounds having either a C1-C12 alkyl group, allyl group or a C6-C12 aryl group as a substituent. |
