Abstract
The invention relates to articles comprising a substrate comprising an ink receptive layer and an ink-jet printed image as well as methods of ink jet printing. The ink receptive layer comprises certain urethane-containing polymers and blends.
Claims23
An imaged article comprising:
- a substrate comprising an ink receptive layer comprising a base polymer selected from the group comprising
- a) a urethane acrylic copolymer,
- b) a blend of at least one polyurethane polymer and at least one acrylic polymer,
- c) a blend of at least two polyurethane polymers,
- and mixtures thereof,
- wherein the ink receptive layer is substantially free of filler;
- and
- a non-aqueous ink jetted image on the ink receptive layer.

A method of ink jet printing comprising:
- providing a substrate comprising an ink receptor layer derived from an aqueous emulsion or dispersion selected from the group comprising
- a) a urethane acrylic copolymer optionally blended with a polyurethane polymer,
- b) a blend of at least one polyurethane polymer and at least one acrylic polymer,
- c) a blend of at least two polyurethane polymers,
- and mixtures thereof,
- wherein the ink receptive layer is substantially free of filler;
- and
- ink jet printing a non-aqueous piezo ink composition on said ink receptive layer.
