Abstract

869,794. Methine dyes; dyeing fibres. FARBENFABRIKEN BAYER A.G. May 16, 1958 [May 23, 1957], No. 15780/58. Classes 2(4) and 15(2). [Also in Group IV(b)] Methine dyes of the general formula:- wherein R, R 3 , R 4 and R 5 are alkyl groups, R 1 is H or an alkyl group, R 2 is H or an alkyl or aryl group, X is an anion, and any of the benzene rings may carry further substituents, are prepared by reacting a 7-alkyl-indole-3-aldehyde with a 1; 3; 3-trialkyl-2-methylene-indoline in an acid medium, or by reacting a 7-alkylindole with a 1; 3; 3-trialkyl-indoline-2-methylene-#-aldehyde in an acid medium. Alternatively, a 7-alkylindole and a 1; 3; 3-trialkyl-2-methylene-indoline may be reacted together in the presence of a dialkyl, diaryl or alkylaryl formamide and a halide of phosphorus or phosphoric acid. The products are useful for dyeing cotton, leather, acetate rayon, polyamide and polyurethane fibres, and articles made from acrylonitrile. An example of dyeing polyacrylonitrile fibres from an acetic acid bath is given. Reference is made to dyes wherein the benzene rings of the indole nuclei may contain methyl, ethyl, methoxy, ethoxy, #- hydroxyethyl, chloro, nitro, carboxylic methyl or ethyl esters, phenacyl, acetylamino, sulphamido or cyano substituents or may have a fused-on benzene ring.
