- such that the radicals resulting from compound II are directly linked to the units of said diazonium salt I, each of said first reaction product and said compound III being present in an amount sufficient to produce said light-sensitive polycondensation product.
- 2. A polycondensation product as claimed in claim 1, wherein R.sup.4, R.sup.6, and R.sup.7 each denote a hydrogen atom or a methyl group.
- 3. A polycondensation product as claimed in claim 1, wherein R.sup.8 comprises a radical having (a) one aromatic ring or (b) two aromatic rings which are linked by a single bond or by --O--, --NH--, --CH.sub.2 -- or --S--.
- 4. A polycondensation product as claimed in claim 1, wherein said diazonium salt comprises a diphenylamine-4-diazonium salt which is unsubstituted or is substituted by an alkyl or an alkoxy group having from 1 to 3 carbon atoms.
- 5. A polycondensation product as claimed in claim 4, wherein said diazonium salt is derived from 4-amino-diphenylamine, 3-methyl-4-aminodiphenylamine, or 3-methoxy-4-aminodiphenylamine.
- 6. A light-sensitive recording material comprising a support and a light-sensitive layer containing as the light-sensitive compound a diazonium-salt polycondensation product as claimed in claim 1.
- 7. A polycondensation product as claimed in claim 1, wherein step (i) comprises condensing about 1 mole of a diazonium salt corresponding to formula I in a strongly acidic medium with about 0.25 to 1.5 moles of a compound corresponding to formula II.
- 8. A polycondensation product as claimed in claim 1, wherein about 0.25 and 1.5 moles of said compound corresponding to formula II is reacted with about 1 mole of said diazonium salt in step (i).
- 9. A polycondensation product as claimed in claim 1, wherein about 0.5 and 1.5 moles of said compound corresponding to formula II is reacted with about 1 mole of said diazonium salt in step (i).
- 10. A process for the production of a light-sensitive, diazonium group-containing polycondensation product, comprising the steps of:
- (a) condensing about 1 mole of a diazonium salt corresponding to formula I ##STR4## wherein R.sup.1, R.sup.2, and R.sup.3 each denote separately a hydrogen atom, a halogen atom, an alkyl group having from 1 to 3 carbon atoms, or an alkoxy group having from 1 to 6 carbon atoms, and
- X denotes the anion of the diazonium salt,
- in a strongly acid medium with about 0.1 to 1.5 moles of a compound corresponding to formula II
- R.sup.4 --O--CH.sub.2 --R.sup.5 (II)
- wherein
- R.sup.4 denotes a hydrogen atom, an alkyl group or an aliphatic acyl radical and
- R.sup.5 denotes a mononuclear or polynuclear aromatic radical, which is unsubstituted or is substituted by at least one halogen atom, alkyl group, halogenated alkyl group, alkoxy group having from 1 to 3 carbon atoms, carboxy group, aryl group, arylmercapto group, or aryloxy group,
- to produce a first reaction product; and thereafter
- (b) reacting said first reaction product with about 0.5 to 1.5 moles of a compound corresponding to formula III
- R.sup.6 --O--CH.sub.2 --R.sup.8 --CH.sub.2 --O--R.sup.7 (III)
- wherein
- R.sup.6 and R.sup.7 each denote separately a hydrogen atom, an alkyl group, or an aliphatic acyl radical, and
- R.sup.8 denotes the radical of a compound selected from the group consisting of aromatic hydrocarbons, phenols, phenolethers, aromatic thioethers, aromatic heterocyclic compounds, and organic acid amides,
- in amounts sufficient to produce said light-sensitive polycondensation product, such that the radicals resulting from compound II are directly linked to the units of said diazonium salt I.
