Abstract
The present invention pertains to an aqueous ink containing mixtures of solvent dyes and disperse dyes suitable for printing on hydrophobic textile substrates.
Claims8
An aqueous ink jet ink for printing on textile, said ink comprising an aqueous vehicle and a water-insoluble colorant dispersed by a polymeric dispersant, wherein said colorant comprises one or more solvent dyes having a structure of Formula I and one or more solvent dyes having a structure of Formula II:
- wherein:
- R1 and R3 are independently CN or optionally substituted C1-C8 alkoxycarbonyl;
- R2 and R4 are independently H or optionally substituted C1-C3 alkyl;
- R5 is CN, optionally substituted C1-C8 alkylsulphonyl or optionally substituted C1-C8 alkoxycarbonyl;
- R6 is optionally substituted C1-C8 alkyl, optionally substituted C1-C8 alkoxycarbonyl, optionally allyl substituted C3-C7 cycloalkyl or optionally substituted C6-C10 aryl;
- R7 is H or independently of R6 and has the definition of R6;
- R8 is optionally substituted C1-C8 alkyl, optionally substituted C1-C8 alkoxycarbonyl, optionally allyl substituted C3-C7 cycloalkyl or optionally substituted C6-C10 aryl;
- R9 is H or independently of R6 and has the definition of R6;
- R10 is H, C1-C8 alkyl or optionally substituted C1-C8 alkyl;
- R11 is CN or H;
- R12 is H or C1-C8 alkyl;
- Y is Cl, Br, F, C1-C5 alkyl, C1-C8 alkylcarbonyl, optionally substituted C1-C20 alkoxycarbonyl, optionally substituted C6-C20 phenoxysulfonate or optionally substituted C6-C20 arylsulfonate;
- and
- X and Z are independently H, NO2, Cl, Br, F, C1-C5 alkyl, C1-C8 alkylcarbonyl, optionally substituted C1-C20 alkoxycarbonyl, optionally substituted C6-C20 phenoxysulfonate or optionally substituted C6-C20 arylsulfonate.
