Abstract
The present disclosure provides a fluid set for printing on textile. The fluid set contains a pretreatment composition, and a mixture of a pigment and a disperse dye as the colorant. The blending of a pigment with a disperse dye as the colorant together with a suitable pretreatment composition provides better image quality.
Claims9
An inkjet printing fluid set for printing on textile, the fluid set comprising:
- a) an aqueous pretreatment composition comprising an ink-aggregating agent and a non-ionic polymeric binder, wherein said ink-aggregating agent is one or more members selected from a cationic polymer, a multivalent metal salt, an organic acid, and mixtures thereof;
- and
- b) an aqueous inkjet ink comprising a colorant and a first polymeric binder,
- wherein the colorant is a mixture of a pigment, a disperse dye and a polymeric dispersant, the first polymeric binder is one or more members selected from the group consisting of acrylic emulsion polymer, styrene acrylic emulsion polymer, vinyl acetate-ethylene copolymer dispersion, and mixtures thereof, and wherein the weight ratio of the disperse dye to the pigment is from 1:20 to 20:1.
