Abstract

Phthalocyanine sulphochlorides are reacted with compounds of the formula <FORM:0785629/IV (b)/1> where X is H or SO3H, R is H, a monovalent metal, alkyl, cycloalkyl, aryl, or aralkyl, R1 is H or alkyl, and R11 is a primary or secondary amino-substituted alkyl group, or where R1 is hydrogen, a tertiary amino-substituted alkyl group. The products may be used as chrome dyes. In examples: (1) copper phthalocyanine-4.41.411.4111-tetrasulphonic acid is converted t its sulphochloride and reacted with 5-b -aminoethylamino - 2 - hydroxy - 3 - sulphobenzoic acid in presence of caustic soda, or similarly with 5 - b - aminoethyl - methylamino - 2 - hydroxy - 3-sulphobenzoic acid or with 5-b -diethylaminoethylamino - 2 - hydroxy - 3 - sulphobenzoic acid; (2) copper or nickel phthalocyanine is directly sulphonated with chlorsulphonic acid, reacted with thionyl chloride, and the sulphochloride reacted with varying amounts of 5-b -aminoethylamino - 2 - hydroxy - 3 - sulphoben - zoic acid; (3) 4.41-diphenyl copper phthalocyanine or 4.41.411.4111 - tetraphenyl copper phthalocyanine are reacted with chlorsulphonic acid and with thionyl chloride and the sulphochloride obtained is reacted with varying amounts of 5-b -aminoethylamino-2-hydroxy-3-sulphobenzoic acid; (4) 4-phenyl copper phthalocyanine-41.411.4111-trisulphonic acid sodium salt is reacted with chlorsulphonic acid and thionyl chloride, and the sulphochloride is reacted with 5-b -diethylamino-ethylamino-2-hydroxy-3-sulphobenzoic acid. Specification 520,199, [Group IV], is referred to.ALSO:5 - b - aminoethylamino - 2 - hydroxy - 3 - sulphobenzoic acid and 5-b -aminoethyl-methylamino - 2 - hydroxy - 3 - sulphobenzoic acid are obtained by reacting 1-amino-2-chlorethane hydrochloride in presence of caustic soda with 5-amino- or methylamino-2-hydroxy-3-sulphobenzoic acid. 5 - b - diethylamino - ethylamino - 2 - hydroxy-3-sulphobenzoic acid is obtained by reacting 1 - diethylamino - 2 - chlorethane hydrochloride similarly with 5-amino-2-hydroxy-3-sulpho-benzoic acid. Specification 520,199, [Group IV], is referred to.
