Abstract
1 - [41 - (acryloylamino)phenyl] - 3 - methyl - 5 -pyrazolone is prepared by reacting 1-(41-aminophenyl)-3-methyl-5-pyrazolone with acryloyl chloride. 4-(acryloylamino)-acetoacetanilide is prepared by reacting 4-aminoacetoacetanilide with acryloylchloride; 2 - chloro - 4 - acryloylamino - acetoacetanilide and 2 - methoxy - 4 - acryloylamino-acetoacetanilide are similarly prepared.ALSO:The invention comprises azo dyes of formula <FORM:0957336/C3/1> wherein X is a direct link or a bridging atom or group, rings B1 and B2 may be substituted, E1 and E2 are residues of coupling components of the acylacetoarylamide, 5-pyrazolone or 5-aminopyrazole series, and may be the same or different, the dyes containing 2-4 sulphonic or carboxylic acid groups and 2-4 groups of formula -NHCOCY=CHY wherein one Y is a hydrogen atom and the other Y is a hydrogen, chlorine or bromine atom, each of the said groups being attached to a carbon atom of an aryl ring in the dye. The dyes are prepared by (a) tetrazotizing a diamine of formula <FORM:0957336/C3/2> and coupling with 2 mols. of the same, or 1 mol. of each of two different, coupling components of the acylacetoarylamide, 5-aminopyrazole or 5-pyrazolone series, the diamine and coupling component together containing the appropriate groups or (b) treating an aminoazo dye of formula <FORM:0957336/C3/3> which contains 2-4 sulphonic or carboxylic acid groups and wherein n=2-4 with an acylating agent, such as an acid halide derived from an acid HOOC.CY=CHY, such as acryloyl chloride, a - or b -chloroacryloyl chloride and b -bromoacryloyl chloride. The dyes may be used to colour natural and regenerated cellulose, wool, silk, polyamide and modified polyacrylonitrile fibres in yellow, orange and red shades. The dyes may also be used to dye cellulose fibres in the presence of acid-binding agents. The following values of X are specified in examples: direct link, -CO-, azoxy, -CH2-, -O-, -S-, -S-S-, -CONH-, -NH.CO.NH-, -SO2-, -CH=CH-, -CH2CH2- and -N=N-. Specification 885,814 is referred to.
