Claims
- 1. An ink which is effective for use in ink jet printing, the ink comprising:(a) from 0.01 to 30 parts by weight of a compound of Formula (1): MvPc(COR1)4 Formula (1) in which: M represents a metal or H; Pc represents a phthalocyanine nucleus; R1 represents OR2; or NR3R4; v is the valence of Pc divided by the valence of M; and R2, R3 and R4 independently represent H or optionally substituted C1-24alkyl; optionally substituted C1-24alkenyl; optionally substituted C1-24alkynyl; optionally substituted C6-24 aryl; optionally substituted C3-24 cycloalkyl; optionally substituted heterocycloalkyl; or optionally substituted heterocycloaryl; and (b) from 70 to 99.9 parts by weight of a liquid medium comprising water and a water dissipatable polymer.
- 2. An ink according to claim 1 wherein R2, R3 and R4 independently represent H or optionally substituted C1-8alkyl.
- 3. An ink according to any one of the preceding claims wherein M is copper.
- 4. An ink according to any one of the preceding claims wherein the water dissipatable polymer is one or more of polyester, polyacrylate, polyurethane and mixtures thereof.
- 5. An ink according to any one of the preceding claims wherein the water dissipatable polymer bears ionised carboxy and/or sulphonate groups.
- 6. One or more compounds of Formula (1) and salts thereof:MvPc(COR1)4 Formula (1) in which:M represents a metal or H; Pc represents a phthalocyanine nucleus; R1 represents OR2; where R2 represents H or optionally substituted C1-24alkyl; optionally substituted C1-24alkenyl; optionally substituted C1-24alkynyl; optionally substituted C6-24aryl; optionally substituted C3-24 cycloalkyl, optionally substituted heterocycloalkyl; optionally substituted hetreocycloaryl, and v is the valence of Pc divided by the valence of M.
- 7. A compound according to claim 6 wherein R2 represents H or optionally substituted C1-8alkyl.
- 8. A compound according to claim 6 or claim 7 wherein M is copper.
- 9. A process for printing an image on a substrate comprising applying to the substrate by means of an ink jet printer, an ink according to any one of claims 1 to 5.
- 10. A substrate which has applied thereon, an ink according to any one of claims 1 to 5.
- 11. A cartridge suitable for use in an ink jet printer containing an ink according to any one of claims 1 to 5.
- 12. One or more compounds according to claim 6, where R2 is optionally substituted C1-24 alkyl; optionally substituted C1-24 alkenyl; optionally substituted C1-24 alkynyl; optionally substituted C6-24 aryl; optionally substituted C3-24 cycloalkyl; optionally substituted heterocycloalkyl; or optionally substituted heterocycloaryl.
