Abstract

Abstract The invention relates to phthalocyanine compounds of the formula <IMAGE> (I) wherein MePc is a copper, cobalt or nickel phthalocyanine radical, R1 is hydrogen or alkyl, X is alkylene, and R2, R3 and R4, are each independently alkyl which is unsubstituted or substituted by hydroxy, alkoxy, phenyl or amino, or R1 and R2, when taken together, are methylene, ethylene or propylene if X is methylene or ethylene, or two or three of R2, R3 and R3, together with the nitrogen atom, form a 5- to 7-membered unsubstituted or substituted heterocyclic ring which may contain one or two additional hetero atoms selected from the group consisting of O, N and S as ring members, An(-) is a cation and M is a cation, and x is greater than y and y is greater than 0, and the sum of x+y is 4 or less than 4. These compounds can be used as dyes, in particular for dyeing and printing cellulosic materials and polyacrylonitrile materials, especially paper.

A phthalocyanine of the formula ##STR35## wherein MePc is a copper, cobalt or nickel phthalocyanine radical, R 1 is hydrogen or alkyl, X is alkylene, and R 2 , R 3 and R 4 are each independently alkyl which is unsubstituted or substituted by hydroxy, alkoxy, phenyl or amino, or R 1 and R 2 when taken together, are methylene, ethylene or propylene if X is methylene or ethylene, or two or three of the substituents R 2 , R 3 and R 4 , together with the nitrogen atom to which they are attached, form a 5- to 7-membered unsubstituted or substituted heterocyclic ring which may contain one or two additional hetero atoms selected from the group consisting of O, N and S as ring members, An.sup.⊖ is an anion and M is a cation, and y is 1 or greater than 1, x-y is 0.1 to 1.5, and the sum of x=y is 4 or less than 4.
Claim 2
Dependent Claim 160 words
A phthalocyanine of the formula ##STR35## wherein MePc is a copper, cobalt or nickel phthalocyanine radical, R 1 is hydrogen or alkyl, X is alkylene, and R 2 , R 3 and R 4 are each independently alkyl which is unsubstituted or substituted by hydroxy, alkoxy, phenyl or amino, or R 1 and R 2 when taken together, are methylene, ethylene or propylene if X is methylene or ethylene, or two or three of the substituents R 2 , R 3 and R 4 , together with the nitrogen atom to which they are attached, form a 5- to 7-membered unsubstituted or substituted heterocyclic ring which may contain one or two additional hetero atoms selected from the group consisting of O, N and S as ring members, An.sup.⊖ is an anion and M is a cation, and y is 1 or greater than 1, x-y is 0.1 to 1.5, and the sum of x=y is 4 or less than 4.
Claim 3
Dependent Claim 14 words
A phthalocyanine compound according to claim 1, wherein MePc is the copper phthalocyanine radical.
Claim 4
Dependent Claim 15 words
A phthalocyanine compound according to claim 1, wherein X is C 2 -C 8 alkylene.
Claim 5
Dependent Claim 151 words
A phthalocyanine compound according to claim 1, wherein R 1 is hydrogen or C 1 -C 4 alkyl or, when taken together with R 2 , is ethylene if X is ethylene; R 2 , R 3 and R 4 are each independently C 1 -C 4 alkyl, C 1 -C 4 hydroxyalkyl or C 1 -C 4 phenylalkyl, with the proviso that only one of these three substituents may be a substituted alkyl radical; or two of the substituents R 2 , R 3 and R 4 , together with the nitrogen atom to which they are attached, is a saturated 5- or 6-membered heterocyclic ring which is unsubstituted or substituted by one or two C 1 -C 4 alkyl and/or C 1 -C 4 hydroxyalkyl groups and which may additionally contain a further O or N atom as ring member; or R 2 together with R 1 is ethylene.
