A process for the preparation of reactive aluminumphthalocyanine dyestuff

Aluminium phthalocyanines of formula (I) are new, where X = Cl or OH; Z = vinyl or group of formula -CH2CH2-Y; Y = substituent eliminated by alkali or sulpho, OH or -NR-T group; T = fibre-reactive heterocyclic group; R = H or 1-6C alkyl group, optionally substituted by OH, SO3M, OSO3M, COOM, methoxy or ethoxy; a = 0-3; b = 0-4; c = 0.5-4; M = H, an alkali metal or an optionally substituted ammonium ion; R , R = H, 1-6C alkyl, optionally mono- or di-substituted by OH, SO3M or OSO3M, phenyl, optionally mono- to tri-substituted by OH, SO3M or COOM, or a group of formula (II), (III) or -(CH2)x-SO2Y (IV); n = 0-3; m = 0 or 1; n + m = 1, 2, 3 or 4; x = 2-6; y = 0-3; W = 1-6C alkylene, -(CH2)2-O-(CH2)2- or a bond; Y = -CH=CH2, -CH2CH2Cl, -CH2CH2OH or -CH2CH2OSO3M; or NR R = a 3-9 membered (un)saturated N-heterocycle or a 5-8 membered (un)saturated heterocycle with another hetero-group selected from O, S, -SO2-, N or -NR ; R = H, 1-4C alkyl, 1-4C hydroxyalkyl, 1-4C chloroalkyl or 1-4C sulphatoalkyl.
