Abstract
Procedure for manufacturing a two-component material for diazotypic photocopies, characterized in that a base is coated with a copyable solution, the solution of which contains diazo compounds corresponding to the general formula: **(See formula)** wherein R1 represents alkyl with 1 to 4 carbon atoms or aralkyl, R2 is alkyl with 1 to 4 carbon atoms, R3 and R4 are the same or different alkyl radicals, with 1 to 5 carbon atoms, X is an acid radical, where R1 and R2 may also be carbon atoms of the same heterocyclic ring, and further characterized by the fact that, as an azo component, compounds according to the general formula are used: **(See formula)** (in which R5 and R6 represent alkyl with 1 to 3 carbon atoms, or are carbon atoms of the same 5- or 6-membered heterocyclic ring), as salts existing in the photosensitive layer.
