Abstract

Compounds of the formula <FORM:1113155/C2/1> wherein R1-R4 are H, alkyl, substituted alkyl, aryl or heterocyclyl at least one being aryl or heterocyclyl are obtained by criss-cross addition of thiocyanic acid with an appropriate azine, e.g. reaction of benzalazine with thiocyanic acid in acetic acid to give 3:7-diphenyl-s-triazolidino-[1: 2-a]-s-triazolidine-1,5-dithione. Reference is also made to the corresponding 3:7-di-a -naphthyl-, 3:7-di-a -furyl-, 3:7-di-(o-chlorophenyl), 3,3,7, 7-tetramethyl- and 3:7-dimethyl-3:7-diphenyl-compounds. The compounds are used as antibronzing agents in photography (see Divisions G2 and G3).
