珂罗版感光胶/聚丙烯酰胺共混物研究

Study on blends of collotype sensitive glue and polyacrylamide

针对珂罗版感光胶夏季易粘纸的缺点,制备了适合夏季使用的珂罗版感光胶。通过实验分析了珂罗版感光胶与水溶性高分子共混物的性质及其对印刷性能的影响。根据实验研究结果进行的实际印刷表明,制备的珂罗版感光胶可明显改善感光胶的成膜质量,同时改善了珂罗版感光胶夏季易粘纸等印刷性能。

This new collotype sensitive glue suitable for summer use is prepared with the purpose of making a remedy for the default of the previous collotype sensitive glue which is apt to stick to paper. Experiments have been done to test the influ- ences on printing properties by the natures of the new collotype sensitive glue and aqueous macromolecular mixture. The printing work done in accordance with the research results shows that this new collotype sensitive glue can improve significantly the film quality of sensitive glue and consequently solve the problem of the previous one.
