The present invention relates to an imaged article comprising a substrate having a primed surface layer. The primed surface layer is comprised of a base polymer having a solubility parameter, molecular weight (Mw) and glass transition temperature within a specified range. The presence of the primer improves the overall image quality by improving at least one property including ink uptake, dot gain, color density and/or ink adhesion. Preferred primer compositions are soluble at least in part in the ink composition resulting in an increase in ink layer thickness that further improves the durability and/or day/night color balance. A variety of substrates may be primed including various sheeting for traffic control signage and commercial graphic films for advertising and promotional displays.

Imaged articles comprising a substrate having a primed surface

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.

Ink jet receptive coating

A receptor medium with an oriented film having at least one microfibrillated surface is described. The receptor medium can receive jettable materials, which include inks, adhesives, particulate dispersions, electrically, thermally or magnetically modifiable materials, biological fluids, chemical reagents and combinations thereof. The microfibrillated surface provides good ink receptive properties particularly for solvent based inks.

Receptor medium having a microfibrillated surface

The present invention relates to primed substrates comprising radiation cured ink jetted images and methods of ink jet printing radiation curable inks that employ applying a primer. The imaged articles are durable for outdoor usage. A variety of polymeric sheets may be primed including various sheeting for signage and commercial graphic films for advertising and promotional displays.
