Abstract

428,158. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. April 17, 1934, No. 11543. Convention date, April 19, 1933. Addition to 415,756. [Class 98 (ii)] Consists in the use of quaternary salts of heterocyclic organic bases to produce the difficultly soluble acid or substantive dyestuff salts. Suitable salts are alkyl-naphthoquinolinium salts, anthraquinolinium salts, thiazolium, e.g. benzthiazolium and naphthothiazolium salts, selenazolium or oxazolium salts ; e.g. halogen alkylates, alkyl perchlorates, alkylsulphates and alkyl toluene-sulphates. In examples (1) an emulsion containing Diamine Pure Blue FF has admixed therewith, prior to pouring, an aqueous solution of 1- ethylquinoline ethylsulphate; (2) a solution of 1-methyl-betanaphthoquinoline perchlorate is added to an emulsion coloured with Chloramine Light Red 7BL.
