近几年来,随着科学技术的飞速发展,重氮感光材料的合成与应用研究受到了国内外进一步的重视,其应用范围日益扩大,品种日益增多。重氮感光材料用于成像材料具有工艺简单、直接获得正象、解象力高、图象清晰、成本较低等优点,因而被广泛用于复印、缩微、印刷等方面。以往生产的重氮感光片,主要采用4-重氮-N,N-二乙基苯胺盐,凡拉明 In recent years, with the rapid development of science and technology, the research on the synthesis and application of diazo photosensitive materials has received more and more attention both at home and abroad. Its application scope is expanding day by day and its varieties are increasing day by day. Diazo photosensitive materials for imaging materials has the advantages of simple technology, direct access to positive, high resolution, image clarity, low cost, which is widely used in photocopying, microfilming, printing and so on. Previous production of diazo photosensitive film, the main use of 4-diazo-N, N-diethyl aniline salt, Van La Ming
