Selective hydroxylation of phenol or phenolic ethers

A radiation-sensitive plate comprises a substrate coated with a radiation-sensitive composition including a component having groups imparting solubility in aqueous solutions and a component having functional groups capable of reacting with a silane compound. The surface of the composition is modified by reaction with a silane compound. The plate gives rise to images of improved ink receptivity and can be developed in aqueous developer liquids after image-wise exposure.

A polymeric compound is derived from a polyhydric material and has pendant sulphonate groups of the general formula ##STR1## where X is an aliphatic, aromatic, carbocylic or heterocyclic group; Y is hydrogen, halogen or an alkyl, aryl, alkoxy, aryloxy or aralkyl group, CO.sub.2 --Z.sup.+, CO.sub.2 R or SO.sub.3 --Z.sup.+ ; Z.sup.+ is a cationic counter ion and R is hydrogen, alkyl, alkylene, aryl or aralkyl group. Wherein the polymeric acompound is produced by reacting a polymer having a plurality of pendant hydroxyl groups with a sulphonato substituted acid or with an ester forming derivative.
