Abstract
This invention relates to an ink jet ink composition comprising water, a humectant, and polymer-dye particles, wherein said polymer-dye particles comprise a colorant phase containing a water insoluble dye, and a polymer phase, said particles being associated with a co-stabilizer. This invention further relates to an ink jet printing method utilizing the above ink jet ink composition.
Claims27
An ink jet ink composition comprising water, a humectant, and polymer-dye particles, wherein said polymer-dye particles comprise a colorant phase containing a water insoluble dye, and a polymer phase, said particles being associated with a co-stabilizer.
24 The ink jet ink composition of claim 14 wherein the composite polymer-dye particles have a mean size of less than about 200 nm and the polymer phase has a molecular weight of greater than about 5000.
An inkjet printing method, comprising the steps of:
- A) providing an ink jet printer that is responsive to digital data signals;
- B) loading said printer with an ink jet recording element comprising a support having thereon an image-receiving layer;
- C) loading said printer with an ink jet ink composition comprising water, a humectant, and polymer-dye particles, wherein said polymer-dye particles comprise a colorant phase containing a water insoluble dye, and a polymer phase, said particles being associated with a co-stabilizer;
- and
- D) printing on said image-receiving layer using said ink jet ink composition in response to said digital data signals.
