Abstract
Textile materials of polymers or copolymers of acrylonitrile or copolymers of dicyanoethylene are dyed or printed with a water-soluble dyestuff which is free from sulphonic and carboxylic acid groups but which contains at least one isothiouronium salt group. Dyeing may be effected from a neutral, acid or slightly alkaline aqueous bath at temperatures up to or above 100 DEG C. Printing may be effected with an aqueous paste containing the usual thickness and adjuvants, the prints being finally steamed. The dyestuffs are preferably of the azo or anthraquinone series, and may be obtained, by treating a water-insoluble dyestuff containing a reactive halogen atom with thiourea or an N-substituted thiourea, such as N-alkyl-thioureas, N-aryl-thioureas, N-alkyl-N1-aryl-thioureas and cyclic thioureas, e.g., ethylene-thiourea (2-thioimidazoline). Alternatively, water-soluble azo dyestuffs containing a isothiouronium salt group may be obtained from diazo and coupling components, at least one of the components containing one or more of the salt groups. Lists of suitable insoluble azo and anthraquinone dyestuffs to be converted, and of suitable azo dyestuff components, are given. The Provisional Specification refers also to the use of dyestuffs containing at least one ternary sulphonium salt group. Specification 650,850 is referred to.
