Abstract
A diazotype material is disclosed containing a novel 2-substituent-3-thio-5-alkoxybenzene diazonium compound of formula I ##SPC1## wherein PA1 X is an anion, PA1 A is the group ##EQU1## or -- OR.sub.4 in which PA1 R.sub.1 is hydrogen, an alkyl radical with 1-8 carbon atoms, a substituted phenyl, cycloalkyl, or aralkyl radical or a heterocyclic radical, PA1 R.sub.2 is an alkyl radical with 1-8 carbon atoms, a --COOR.sub.5 group in which PA1 R.sub.5 signifies hydrogen, an alkyl radical with 1-8 carbon atoms, a cycloalkyl, aryl, aralkyl, or alkylaryl radical or a heterocyclic radical, or a group of ##EQU2## in which R.sub.6 and R.sub.7 stand independently of one another for hydrogen or a hydroxy, alkoxy, alkyl with 1-4 carbon atoms, or phenyl radical, PA1 R.sub.1 and R.sub.2 together with the nitrogen may be a morpholino, a methyl-substituted morpholino, pyrrolidino, or piperidino group, PA1 R.sub.3 is an alkyl radical with 1-8 carbon atoms, an aralkyl, alkoxyaryl, haloaryl, alkoxyalkyl, or cycloalkyl radical or a heterocyclic radical, and PA1 R.sub.4 is an alkyl, branched or unbranched lower alkyl, cycloalkyl, or aralkyl radical.
