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.
Claims21
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 polyurethane polymer has an elongation of at least 100% and
- the ink receptive layer is substantially free of filler;
- and a non-aqueous ink jetted image on the ink receptive layer.
