对充分导入间苯二酚的桐油间苯二酚树脂和双叠氮化合物所组成的感光体系的光发色交联机理进行了研究.证明树脂中间苯二酚基残留的反应活性点是易与氮烯(氮宾)反应导致交联的主要因素.其发色过程是由于生成氮-氧醌式结构所致.树脂中残留双键与叠氮化合物的光交联作用无疑是存在的,但实验证实它不是发色交联的主导因素.
The photochromic cross-linking mechanism of the photosemisic acid system composed of tung oil resorcinol resin and bisazide fully introduced into resorcinol was studied. It was proved that the resorcinol residue in the resin was easily reactive The reaction of azobis (nitrenes) leads to the main factor of cross-linking, and its color development is due to the formation of a nitrogen-oxygen quinone structure. There is no doubt that the photocrosslinking of the residual double bond in the resin with the azide compound exists Experiments confirmed that it is not the dominant factor in hair color crosslinking.
