Abstract

Natural or regenerated protein textile materials are dyed or printed with an aqueous dispersion of one or more disperse azo dyestuffs which are free from sulphonic and carboxylic acid groups but which contain at least one group of the formula:-CO-Y-A-Z wherein Z represents a halogen atom or an oxiranyl group, A represents a substituted or unsubstituted alkylene radical and Y represents a direct link or a group of the formula -NH-, <FORM:0875106/IV(c)/1> wherein A and Z are as above and B represents a substituted or unsubstituted alkyl or aryl radical. Specified radicals A are methylene, ethylene, trimethylene, hydroxytrimethylene, tetramethylene, a : b -dimethylethylene and isopropylene. Specified radicals B are methyl, ethyl, propyl, phenyl and hydroxyethyl. Dyeing is effected at temperatures up to or above 100 DEG C., at a constant or varying dyebath pH value and the dyebath may also contain ammonium sulphate, acetate or phosphate, sodium bicarbonate, sulphuric, phosphoric, formic or acetic acid, ethyl lactate or tartrate and anionic, cationic or non-ionic surface-active agents. Printing is followed by steaming and the printing paste may contain acid-binding agents and the usual thickeners and adjuvants such as sodium alginate, methyl cellulose, oil-in-water or water-in-oil emulsions, ethanol, urea and sodium-m-nitrobenzene sulphonate. Specified disperse azo dyes are 2-bromo-4-chloroacetyl-41-N : N-bis (b -hydroxyethyl) aminoazobenzene and 2-bromo- 4-chloroacetyl- 21-methyl- 41-(N- b -hydroxyethyl- N- b -cyanoethyl) aminoazobenzene.
