In addition, when the modified PVA resins fulfilled requirements in the following: 1 the acetalization degree varied from 60 mol% to 80 mol%, 2 the esterification degree varied from 10 mol% to 20 mol%, 3 the amount of hydroxyl group was 5-25 mol%, 4 the range of value of B/P(the mass ratio of the binder to diazo resin) was from 4 to 4.5,5 the range of its molecular weight was from 4×10^5 to 8×10^5, the negative PS plate obtained had excellent sensitivity, hydrophobic property, good developability, good ink receptivity and good scratch resistance.
因此其分子量、酯化度和缩醛度的确定，必须综合考虑各项性能之间的平衡。缩醛度为60-80 mol%，酯化度10-15mol%，羟基5-25 mol%，分子量约为4-8万，B/P为4-4.5时，制得的阴图PS版的感度、显影性、着墨性和耐磨性都较好。
