Process for the preparation of new phthalocyanine dyes |
| abstract |
Phthalocyanine dyes: (where Pc is phthalocyanine; L is substd. NH2 gps.; M is (substd.)NH2 gp. not identical to L; a is 0-3; b is 1-2 and c is 0-2 with proviso that a+b+c is not >4) are prepd. by treating an aqs. suspension of a Pc-sulphochloride : (where d is 2-4; a+d is not >4) with an amine having a cation and opt. with : (where R3 and R4 are H or (substd.) hydrocarbon, or together with N form a 5- or 6-membered ring). |
