Abstract

Dye releasing compounds which release dyes corresponding to formula I ##STR1## wherein R.sup.1 denotes alkyl, aryl, arylamino, alkoxy or aryloxy, PA0 R.sup.2 denotes H or halogen, PA0 R.sup.3 denotes alkyl with 2-4 carbon atoms, PA0 R.sup.4 denotes H or one or more substituents such as alkyl, alkoxy, acylamino or halogen, including a substituent in the ortho-position to the group ##STR2## which together with R.sup.5 completes a cyclic amino group, R.sup.5 denotes alkyl with up to 4 carbon atoms or a group which together with a subsituent denoted by R.sup.4 or together with R.sup.6 completes a cyclic amino group, and PA0 R.sup.6 denotes alkyl with up to 4 carbon atoms or a group which together with R.sup.5 completes a cyclic amino group are suitable for the production of light-stable cyan colour images.
