Process for the preparation of relief-type recordings using diazonium condensation product and amine resin as light-sensitive recording layer and incoherent radiation source for recording image |
摘要 |
This invention relates to an improvement in a light-sensitive recording material comprising a support and a light-sensitive layer including a diazonium salt polycondensation product composed of recurrent units of the general types (A-N2X) and (B) which are connected with each other by bivalent intermediate members derived from a condensable carbonyl compound and wherein A is the radical of a diazonium salt which comprises at least two isocyclic or heterocyclic aromatic rings and which in at least one position of its molecule is capable of condensation with formaldehyde in an acid medium, B is the radical of a compound free of diazonium groups which in at least one position of its molecule is capable of condensation with formaldehyde in an acid medium, and X is the anion of the diazonium salt, the improvement that the light-sensitive layer additionally contains about 6 to 20 parts by weight of amine resin per part by weight of the polycondensation product.
