Claims20
A dye comprising a phthalocyanine dye represented by one of the general structures I to VIII, a naphthalocyanine dye represented by one of the general structures XI to XVI, or a bridged phthalocyanine/naphthalocyanine dye represented by one of the general structures IX, X, and XVII:
- wherein:
- R is H, alkyl substituted alkyl, or SO3M1;
- M1 is H, monovalent cations, or NR44+;
- OR can be replaced by a halogen;
- R1 is H, alkyl, or substituted alkyl or aryl with carbons from 1 to 50;
- R2 is H, CH═CH2, or (—CH═CH—)nH
- n is 1 to 5000;
- R3 is a divalent linking group;
- M is a monovalent, a divalent, a trivalent, a tetravalent or a pentavalent metal ion or transition metal ion;
- X is H, alkyl, substituted alkyl, aryl, substituted aryl, SO3 M1, OH, OCOR2;
- COO M1, PO3 M12, NR44+Y−, or O(CH2CH2O)mCH3 (m=1 to 500), where at least one of the X in the dye is sulfonate, phosphate or polyethylene glycol, where Y is independently selected from a halide, sulfate, sulfonate, OH−, and OSO3−;
- and
- R4 is H, alkyl, substituted alkyl, aryl, or substituted alkyl.
