Abstract

In the process of the parent Specification, wherein textiles are coloured and given a crease-resistant or shrink-resistant finish or a modified handle by applying an aqueous medium containing a resin-forming composition, a dyestuff reactive with the resin or the fibre and an acid catalyst and finally baking, the dyestuff employed contains, attached to a carbon atom of an aryl ring present in the dyestuff, at least one group:- -A-X wherein A represents a bridging atom or group and X represents an alkyl or cycloalkyl radical containing at least two hydroxy groups and optionally containing a keto or aldehydic group. Specified bridging atoms or groups A are the following: -O-, -S-, <FORM:0906140/IV (b)/1> , -SO2-, <FORM:0906140/IV (b)/2> <FORM:0906140/IV (b)/3> <FORM:0906140/IV (b)/4> , -NHCO-, <FORM:0906140/IV (b)/5> <FORM:0906140/IV (b)/6> and <FORM:0906140/IV (b)/7> wherein R, R1 and R11 each represent a hydrogen atom or a substituted or unsubstituted alkyl radical, Z represents a hydrogen atom or the group <FORM:0906140/IV (b)/8> or a substituent such as a chlorine or bromine atom or an alkyl, aryl, alkoxy, aryloxy, alkylmercapto or arylmercapto radical or an amino or substituted amino group or a hydroxy or a thiocyano group, Z1 represents a hydrogen or halogen atom or a nitro, cyano, alkyl, aryl, acyl or carboalkoxy group, P represents -SO2-, -CO- or -NHCO-, Q represents a substituted or unsubstituted alkylene radical and m and n each represent 1 or 2 and may be the same or different. Examples describe the dyeing of cotton, and lists of suitable dyestuffs of the azo, anthraquinone and phthalocyanine series are given.
