Abstract
Methine dyes are prepared by condensing, in the presence of a basic condensing agent, a compound of the general formula <FORM:0610569/IV (c)/1> wherein R1 is a hydrocarbon group and R4 alkyl or aralkyl with a compound of the formula <FORM:0610569/IV (c)/2> wherein R5 is H or a hydrocarbon group, R2 is an alkyl hydroxylkyl, aralkyl, or hydroxyaralkyl group, R3 is H or alkyl or aralkyl, D1 is the residue of a 5- or 6-membered heterocyclic ring, which may have fused-on rings, D2 is the residue of a heterocyclic nitrogen ketomethylene ring, X is an anion, and n is 0 or 1. Dyes specified are such that R1 is ethyl and R4 methyl, and derived from p-toluquinaldine methyl-p-toluenesulphonate, 1-methylbenzthiazole methyl- or ethyl-p-toluenesulphonate, 1-methylbenzoxazole methyl-p-toluenesulphonate, 1-methyl-b -naphthathiazole methyl-p-toluenesulphonate, and m -thiazoline methyl-p-toluenesulphonate; both R1 and R4 are ethyl and derived from 1-methylbenzthiazole methyl-p-toluenesulphonate or b -hydroxyethiodide; and R1 is ethyl and R4 benzyl and derived from 1-methylbenzthiazole methodide. Specifications 489,335, 547,060, [Group XX], and 597,446 are referred to.
