A light sensitive material suitable for coating onto a support to produce a light sensitive plate for use in, for example, the manufacture of a printing plate comprises groups of the formula: ##STR1## attached to carbon atoms, wherein ##STR2## wherein R.sub.5 represents a hydrogen atom or an alkyl group; R is an aromatic radical; a is zero or unity; R.sub.1, R.sub.2 and R.sub.3 are hydrogen atoms, halogen atoms, cyano groups, or specified aliphatic or aromatic groups; X is a deactivating group; R.sub.4 is a hydrogen atom, a carboxyl group, a cyano group or a specified aliphatic or aromatic group; and Ph is a phenyl group. The material may be produced by reacting a polymer containing epoxide groups, hydroxyl groups, or primary and/or secondary amino groups with the halosulphonyl group of a compound having the forula: ##STR3## wherein R, R.sub.1, R.sub.2 R.sub.3, and a have the above meanings, wherein X has the above meaning or is a halosulphonyl group and R.sub.4 has the above mentioned meaning or, in the case where X is a deactivating group, is a halosulphonyl substituted group.
一种适合涂覆在支撑物上以制成光敏板的光敏材料,例如用于制造印刷版,包括式子的基团:##STR1##连接到碳原子上,其中##STR2##其中R.sub.5代表氢原子或烷基;R是芳基;a为零或统一;R.sub.1、R.sub.2和R.sub.3为氢原子、卤素原子、氰基或指定的脂肪或芳香族基团;X为去活化基团;R.sub.4为氢原子、羧基、氰基或指定的脂肪或芳香族基团;Ph为苯基。该材料可以通过将含有环氧基团、羟基或主要和/或次要氨基团的聚合物与具有式子的卤磺酰基团的化合物反应而制得:##STR3##其中R、R.sub.1、R.sub.2、R.sub.3和a具有上述含义,其中X具有上述含义或是卤磺酰基团,而R.sub.4具有上述提到的含义,或者,在X是去活化基团的情况下,是卤磺酰取代基团。
