Light-sensitive, diazonium group-containing polycondensation product, process for its production, and light-sensitive recording material containing this polycondensation product

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 wherein R4 is H, alkyl or acyl, and R5 is an optionally substituted aromatic radical, and (c) a compound corresponding to the formula 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.

Light-sensitive polycondensation product containing diazonium and dialdehyde groups, and light-sensitive recording material prepared therewith

A light-sensitive diazonium group-containing polycondensation product of a diazonium salt corresponding to the general formula STR1 wherein R1, R2, and R3 denote hydrogen atoms, halogen atoms, alkyl groups having 1 to 3 carbon atoms or alkoxy groups having 1 to 6 carbon atoms, and X denotes the anion of the diazonium salt, and an aldehyde selected from the group consisting of dialdehydes, acetals of dialdehyde hydrates, and esters of dialdehyde hydrates, a process for producing such a light-sensitive polycondensation product and a light-sensitive recording material comprising a layer support and a light-sensitive layer containing such a light-sensitive polycondensation product.
