Examples are given in which the following constituents are used :-p-amidodiphenylamine sulphonic acid, a-naphthylamine, and a,-naphthola2 - monosulphonic acid; p-amido - phenyltolylamine sulphonic acid, a-naphthylamine, and #1- naphthol-#2#3-disulphonic acid-R ; and p-amidodiphenylamine disulphonic acid, a-naphthylamine, and #-naphthol.
