Abstract: A light-sensitive, diazonium group-containing polycondensation product is described which comprises (a) an optionally substituted diphenylamine-dianzonium salt I. (b) a compound corresponding to the formula II R4-O-CH2-R5 (II) wherein R4 is H, alkyl or acyl, and R5 is an optionally substituted aromatic radical, and (c) a compound corresponding to the formula III R6-O-CH2-R8-CH2-O-R7 (III) wherein R6 and R7 are H, alkyl, or acyl and R8 is the radical of a compound selected from the group consisting of aromatic hydrocarbons, phenols, phenolethers, aromatic thioethers, aromatic heterocyclic compounds, and organic acid amides, with the radicals resulting from compound II being directing linked to the units of the diazonium salt I. In the production of the polycondensation product, I is first condensed with II and then with III. The product is suitable for use as a light-sensitive substance in recording materials, particularly in printing plates, and yields light-hardening products which have an increased oleophilicity.
