1406887 Dyestuff mixtures IMPERIAL CHEMICAL INDUSTRIES Ltd 22 May 1973 [29 June 1972] 30499/72 Addition to 1321902 Heading C4P [Also in Division D1] Dyestuff mixtures consist of (a) 10% to 60% by weight (based on the total weight of dyestuffs in the mixture) of a water insoluble dye free from sulphonic acid and carboxylic acid groups and of formula in which W<SP>1</SP> is H, Cl, Br, CN or acylamino group NHZ<SP>1</SP>, and W<SP>2</SP> is H, Cl, Br, CN, NO 2 provided that one of W<SP>1</SP> and W<SP>2</SP> is H; Z and Z<SP>1</SP> are each independently acyl groups of formula COV and SO 2 U, V is H or NH 2 or lower alkyl (C 1-4 ) lower alkoxy, phenyl or phenoxy radical optionally substituted, U is a lower alkyl or phenyl radical optionally substituted, Y is H, lower alkyl or lower alkoxy, R is lower alkyl or phenyl which may be substituted or a group of formula -A-COO-A<SP>1</SP>(X)m, A is an alkylene radical haying 1 to 6 carbon atoms, m is 1 or 2 and A<SP>1</SP> is a di- or tri-valent alkane radical depending upon the value of m containing up to 4 carbon atoms, X is CN, lower alkoxy, optionally substituted phenoxy, hydroxy, Cl, Br, lower alkoxycarbonyl, optionally substituted phenoxycarbonyl, carbonamido, carbonanilido, N-loweralkyl or N,N-di-lower alkyl carbonamido, NH 2 , anilino, N-lower alkylamino, N,N-di-lower alkylamino, lower alkylsulphonyl, phenyl sulphonyl or a radical UCO-or UCONH-, (b) from 30% to 90% by weight of (1) at least one disperse dye of formula which can contain up to 30% of its own weight of a disperse dye of formula in which L is a phenyl radical which may be substituted by one or more chlorine or bromine atoms or by hydroxy, NH 2 , lower alkyl, lower alkoxy, hydroxyloweralkoxy, N-lower alkylyamino, acylamino, N,N-di(lower alkyl)-amino, carbo lower alkoxy, lower alkoxycarbonyloxy or lower alkylcarbonyloxy groups, Q is a hydrogen atom or lower alkyl radical which may be substituted, and/or (ii) one or more disperse dyes of formula in which J and J<SP>2</SP> each independently represent a lower alkyl, amino lower alkyl, cyano lower alkyl, chloro lower alkyl, bromo lower alkyl, acylamino lower alkyl, hydroxy lower alkyl or lower alkoxy lower alkyl radicals or J<SP>1</SP> and J<SP>2</SP> are identical and each represent a substituted phenyl as defined for L provided that when dyes of Formula III and IV are both present the values of J<SP>1</SP>, J<SP>2</SP> and L are not identical and (c) 0% to 25% by weight (based on the total weight of the dyes present in the mixture) of at least one yellow to red disperse dystuff as defined. The dyestuff mixtures are obtained by mixing the dyestuffs in the required proportions.
