有机感光材料种类很多。有机发色感光材料是指在光的作用下,能引起色的变化(无色→有色,A色→B色),从而形成有机化合物的画面。能引起色变化的有机光化学反应主要有以下几类: 1.光分解反应,如:重氮化合物感光材料;游离基感光材料;叠氮化合物感光材料;光敏变色感光材料。2.光氧化还原反应,如:光敏变色感光材料。3.光互变异构反应,如:光敏变色感光材料。
There are many kinds of organic photosensitive materials. Organic hair color light-sensitive material refers to the role of light, can cause changes in color (colorless → colored, A color → B color), thus forming a picture of organic compounds. Organic photochemical reactions that can cause color changes are mainly the following categories: 1. Photodecomposition reaction, such as: diazo compounds photosensitive materials; free radical photographic materials; azide compound photographic materials; photosensitive photochromic photographic materials. 2. Photooxidation reduction reaction, such as: photosensitive discoloration photosensitive material. 3. Optical tautomerism reaction, such as: photochromic photosensitive material.
