羟丙基甲基纤维素酯或一醋酸纤维素酯与邻苯二酸的酯化物做感光胶片碳黑防光晕层粘结剂有很多优点。根据伊斯曼柯达公司巴尔德论述,在感光胶片乳剂层曝光时有96％的光线被乳剂层吸收。而大约有4％的光线透过乳剂层后,在乳剂层与片基层之间或在片基与空气层之间的界面处发生反射和散射,这是由于介质的折射有细小的差异而引起的。 Hydroxypropyl methyl cellulose ester or a cellulose acetate ester and phthalic acid ester film to make light-sensitive film anti-halo layer adhesive has many advantages. According to the paper by Eastman Kodak Balder, 96% of the light is absorbed by the emulsion layer during exposure of the emulsion layer. Approximately 4% of the light passing through the emulsion layer reflects and scatters at the interface between the emulsion layer and the substrate or between the substrate and the air layer due to small differences in the refraction of the medium .
