Abstract
Phthalocyanines are produced by reacting chlorine- or brominecontaining phthalocyanines with amines containing at least one reactive hydrogen atom attached to nitrogen. Suitable initial materials are the metal-containing and metal-free dyestuffs obtained by the action of halogenating agents on phthalocyanines such as those mentioned in Specification 470,079. These are caused to react either directly, or in the presence of solvent or diluent, with amines such as methylamine, dimethylamine, butylamine, ethanolamines, butylethanolamines, ethylene diamine, polyethylene polyamines, dodecylamines, methyldodecylamine, octodecylamine, octodecenylamine, dioctodecylamine, cyclohexylamine, methylcyclohexylamine, aniline, toluidine, xylidine, aminomethoxybenzene, aminomethylmethylbenzene, aminohydroxybenzene, aminonaphthalene, aminodiphenylene oxide and sulphide, aminobenzene carboxylic acids, aminohydroxy benzene carboxylic acids, phenylene diamines, aminoacetic acid, methylaminoacetic acid, aminopyridine, aminoquinoline, aminocollidine, piperidine, lupetidine, and amino compounds of anthracene, anthraquinone, carbazole, azanthraquinones, benzanthrones, dibenzanthrones, iso-dibenzanthrones, azobenzanthrones, chrysenes, pyrenes, anthrapyrimidines, anthradipyrimidines, anthrapyridones, anthraquinonebenzacridones, pyrroloanthrones, pyridinoanthraquinones and pyridino-benzanthrones. Suitable diluents are aromatic hydrocarbons, aromatic nitrohydrocarbons and tertiary amines. Metals promoting halogen exchange such as zinc, copper, silver powder, sodium and sodium amalgam may be added and p the reaction may be carried out under pressure. The examples describe the reaction of (1) tetra-chlor-copper-phthalocyanine with 1 - amino - 4 - methylbenzene, 2 - amino - naphthalene, paratoluidine, and dodecylamine; (2) penta-chlor-copper phthalocyanine with benzylamine, para-phenetidine, 1-amino-anthraquinone and 1 : 4-diamino-anthraquinone; (3) metal-free tetra-chlor-phthalocyanine with benzylamine, and 1-amino-naphthalene; (4) tetra - deca - chlor - copper - phthalocyanine with cyclo-hexylamine and dodecylamine; (5) various chlorinated copper phthalocyanines of uncertain formula with aniline, 1-aminonaphthalene, benzidine, para - phenylene - diamine, piperidine, and sodium tauride. Samples have been furnished under Sect. 2 (5) of (A) a blue powder obtained by reacting alphaamino-naphthalene with a brominated copper phthalocyanine, and (B) a greenish blue powder obtained by reacting a mixture of alpha-aminonaphthalene and para-toluidine with a copper phthalocyanine containing chlorine and bromine.
