説明

A highly sensitive photopolymerization initiation system, corresponding to the visible laser with the wavelength of 488nm, was investigated. We already reported an electron-transfer initiation system consisting of a merocyanine dye and a triazine initiator. The sensitivity of this system was too low to commercially apply it to CTP. We have found that a-amino ketones have an excellent ability to improve its sensitivity by using them as additives to our initiation system. These ketones have been found to improve the sensitivity more than twice and to show excellent thermal stability, which satisfy the requirements to realize commercialization of CTP.
