Abstract This invention relates to a process for the production of reprographic copying materials which comprises applying a lightsensitive layer to a support by evaporation at reduced pressure, the layer comprising at least one light-sensitive quinone diazide sulfonic acid derivative of the general formulae IN WHICH X is selected from the group consisting of an alkoxy group having one to 10 carbon atoms, A CYCLOALKOXY GROUP HAVING FIVE TO 12 CARBON ATOMS, AN ARYLOXY GROUP HAVING SIX TO 15 CARBON ATOMS, OR AN AMINE GROUP DERIVED FROM A PRIMARY OR SECONDARY AMINE CONTAINING ALKYL GROUPS HAVING ONE TO 10 CARBON ATOMS, CYCLOALKYL GROUPS HAVING FIVE TO 12 CARBON ATOMS OR ARYL GROUPS HAVING SIX TO 14 CARBON ATOMS AS SUBSTITUENTS AT THE NITROGEN OR FROM A MONONUCLEAR N-heterocyclic compound, Y is selected from the group consisting of an aryloxy group having six to 15 carbon atoms, or AN AMINE GROUP DERIVED FROM A PRIMARY OR SECONDARY AMINE CONTAINING ALKYL GROUPS HAVING ONE TO 10 CARBON ATOMS, CYCLOALKYL GROUPS HAVING FIVE TO 12 CARBON ATOMS OR ARYL GROUPS HAVING SIX TO 14 CARBON ATOMS AS SUBSTITUENTS AT THE NITROGEN OR FROM A MONONUCLEAR N-heterocyclic compound, R and R'' are mononuclear aromatic groups, and N IS 0 OR 1.
