Abstract
Procedure for the preparation of water-insoluble styryl dyes of the formula **(See formula)** where R1 and R2 signify substituted alkyl groups which, together with radicals A1 or A2, can each form a ring; R3 represents an alkylene group, optionally substituted; R4 signifies a direct bond or, preferably, an alkylene group, optionally substituted; Y1 and Y2 signify cyano, carboalkoxy, or arylsulfonyl groups; A1 and A2 signify para-phenylene groups, optionally substituted; and Z stands for a colorless bridge, devoid of SO2 groups, characterized by: a) reacting the dyes of the formula **(See formula)** where X1 and X2 represent a group containing at least one reactive hydrogen atom, preferably an amine, mercaptic or hydroxy group or their reactable derivatives; R1, R2, R3 and R4 are alkyl or alkylene groups, optionally substituted; and A1, A2, Y1 and Y2 have the same meaning as before, with a bifunctional compound, lacking SO2 groups, to form the dyes of this invention, of formula (1); O well b) condensing the dialdehyde of the formula **(See formula)** or its aldimine, with a cyano compound of the formula **(See formula)** in the 1: 2 molar ratio, or c) reacting the monostyril dyes of the formulas **(See formula)** having a reactable hydrogen atom attached to an amine group, with a bifunctional compound of the formula **(See formula)** where n is an integer worth 1 or 2, while Y'1 and Y'2 are each a reactable negative radical, preferably a halogen atom, when n = 2; and they form together with Z a diepoxide compound tending to the addition, when n = 1; O well d) when in the styrene dyes of the formulas **(See formula)** cited in a), X1 and X2 signify an SH group, since said dyes are converted by oxidation to a dye of formula (1) in which Z then constitutes a bridge of formula -S-S-.
