Abstract

1359058 Disazo solvent dyes FARBWERKE HOECHST AG 8 Oct 1971 [10 Oct 1970] 46887/71 Heading C4P The invention comprises disazo solvent dyes having the general formula where R 1 is H or C 1-4 alkyl or alkenyl; and R 2 and R 3 independently represent an alkyl or alkenyl group, with the proviso that the total number of carbon atoms in said groups is from 3-20, or R 2 and R 3 together with the quaternary carbon atoms form a cycloalkyl or cycloalkenyl ring. The dyes may be obtained by coupling a diazotized aniline with α-naphthylamine, diazotizing the resulting monoazo dye and coupling it with an appropriate 2,3-dihydroperimidine. The dyes give red and violet shades in oils, fats, waxes, plastics, material and synthetic resins, textile materials and paper.
