the action mechanism of N-ethyl-N'-phenylpiperazine-one of components in the photo-initiation system has been studied. It was found that the titled amine in which although dimethyl aniline and triethyl amine both were contained
possesses less efficiency of photoinitiation while it was composed with ketone as an initiated system. This phenomenon was discussed and the mechanism was further comfirmed by the addition of acid for promoting of photoinitiated efficiency by the quaternary ammoniation of one of amines in piperazine.
