【摘要】 为了提高酸敏变色记录材料的图象稳定性能,进行了添加苯酚、水杨酸、乙酸、苯甲酸等酸性添加剂的试验。其光谱特性显示,加入适量的苯酚、水杨酸添加剂后,图象的稳定性能得到改善,而乙酸、苯甲酸添加剂却不能起到这种作用。试验中采用核磁共振技术作了检测,在加入苯酚添加剂时有氢质子释放,抑制了醌式结构向初始状态的回复,改善了图象的稳定性能。更多还原

【Abstract】 The effects of some acid additives, such as phenol, salicylic acid, acetic acid, and benzoic acid etc. on the image stability of the acid sensitive film have been examined. The spectral measurements show that the image stability can be improved by adding certain amount of phenol, but acetic acid and benzoic acid have no such effect. The mechanism of improvement of the image stability by adding phenol has been discussed. It is most probabl ethat proton is released from phenol and inhibits the reversion of quinone, so the image stability is improved.更多还原
