Abstract: The invention comprises triarylmethane dyes having the formula in which R1 denotes a low molecular weight alkyl group, R2 and R3 are hydrogen atoms or aliphatic, cycloaliphatic, aliphatic-cycloaliphatic radicals which may be connected to form a fused cycloaliphatic ring, and Y is a chlorine or bromine ion. The dyes of the above formula are made by condensing together p,p1-bisdialkyl-aminobenzophenones of formula with a secondary amine having the formula in the presence of a condensing agent containing chlorine or bromine. In formulae III and IV, R1, R2 and R3 have the meanings as above; as condensing agents phosphorus trichloride, tribromide, pentachloride, oxychloride, oxybromide and phosgene are specified. The reactions are carried out in inert solvents, e.g. toluene and xylene, and the dyes produced have good solubility in alcohol and castor oil.
