  • Patent number: 7025453
    Abstract: The present invention relates to an imaged article including a substrate having a primed surface layer. The primed surface layer is included 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.
    Type: Grant
