Abstract: Printable, coated plastic substrates are disclosed. Plastic substrates are preferably films substrates, which when coated with an epoxy coating, optionally containing anti-abrasive particulate, provide excellent wet-scratch resistance and ink gloss. The epoxy coated plastic films are particularly suitable for use as printable labels.

Abstract: A polymeric film substrate having on at least one surface a prime coating of the type which causes destructive film blocking between contacting layers. This prime coating is top coated with pigmented or non-pigment polyester ink base so as to eliminate the blocking. This top coating is a excellent base for printing inks.

Abstract: A printable film structure comprising a polymeric film substrate having on at least one surface thereof a prime coating of the type which causes destructive film blocking between contacting layers of such coated films, said prime coating having thereon a continuous copolyester coating consisting essentially of the polyester condensation product of the following monomers or their polyester forming equivalence:(a) about 60 to 75 mole % of terephthalic acid;(b) about 15 to 25 mole % of at least one aliphatic dicarboxylic acid of the formula HOOC(CH.sub.2).sub.n COOH, wherein n ranges from about 1 to 11;(c) greater than from about 6 up to about 15 mole % of at least one sulfomonomer containing an alkali metal sulfonate group attached to a dicarboxylic aromatic nucleus; and(d) stoichiometric quantities of about 100 mole % of at least one copolymerizable aliphatic or cycloalphatic alkylene glycol having from about 2 to 11 carbon atoms.
