ABSTRACT OF THE DISCLOSURE A photosensitive mixture comprised of (a) a diazonium salt polycondensation product comprising recurring units of the formulas A-N2X and B, which units are linked by bivalent intermediate members derived from a carbonyl compound which is capable of condensation, wherein the A-N2X units are derived from aromatic diazonium compounds that are capable of con- densation with formaldehyde, and the B units are derived from compounds which are free from diazonium groups and are also capable of condensation with for- maldehyde in a strongly acidic medium; (b) a compound which can be polymerized by a free-radical process; (c) a photopolymerization initiator; and (d) a polymeric binder that is insoluble in water, but soluble in organic solvents can be used in the production of photosensitive printing plates and photoresists.
