Patent ID: 7758965

Claim:
A printable film comprising a polyolefin substrate and at least one uncured surface layer printable by a radiation curable ink, said layer being a covering at least one face of said substrate, the major component of the layer being a water-dispersible acrylic polymer able to provide a smooth film and open surface, the layer further containing (a) an ethylenically unsaturated compound having 2 to 5 ethylenical bonds per molecule in the form of a trifunctional acrylate in an amount of 2 to 15% by weight of the water dispersible acrylic polymer and (b) a cross linking agent in the form of a coordinated metal ligand in an amount of 1 to 5% by weight of the water dispersible polymer, said layer not containing an addition polymerization photoinitiator, wherein the substrate is an oriented polypropylene film provided on both surfaces with skin layers and a polyurethane acrylate primer is applied between the surface layer and a skin layer.
