ABSTRACT:
Disclosed is a two-component diazotype material comprising a support and a light-sensitive layer containing (a) at least one diazonium compound derived from p-phenylenediamine and carrying a basic heterocyclic radical in the 4-position and ether groups in the 2- and 5-positions, (b) a coupler component, and (c) an acid stabilizer, the diazonium compound being present in the form of a benzenesulfonate or toluenesulfonate. The disclosed materials have a good storability and are easily developed.
