Abstract
A directly printable composition is provided. The composition is the reaction product of a vinyl-functional monomer, a chlorinated olefinic resin, optionally an amide-functional monomer, and optionally a free radically polymerizable silicone-containing material. The reaction product is stable and can be applied to a variety of substrates. A variety of inks can be directly printed on the coating.
Claims12
A directly printable film comprising polymeric substrate having first and second major surfaces and a layer of directly printable release coating on at least one of the first and second major surfaces which release coating comprises the reaction product of
- (i) from 50 to 95 weight percent of a vinyl functional monomer comprising the acrylic and methacrylic acid esters of a non-tertiary alcohol containing from 1 to 14 carbon atoms;
- (ii) from 5 to 50 weight percent of a chlorinated olefinic resin;
- (iii) from 0 to 30 weight percent of an amide-functional monomer;
- (iv) from 0.01 to 5 weight percent of a free radically polymerizable siloxane-containing component containing ##STR2## units.
A directly printable film prepared by combining (i) from 50 to 95 weight percent of a vinyl-functional monomer that comprises an acrylic or methacrylic acid ester of an alcohol, (ii) from 5 to 50 weight percent of a chlorinated olefinic resin, (iii) from 0 to 30 weight percent of an amine-functional monomer and, (iv) from 0.05 to 2 parts by weight of a free radically polymerizable siloxane-containing material in a suitable reaction medium, and reacting the components to form a polymer, and applying the polymer to a polymeric substrate.
A directly printable pressure sensitive adhesive tape comprising a polymeric substrate having first and second major surfaces, a layer of a pressure sensitive adhesive on the first major surface of the polymeric substrate, and a layer of a directly printable release coating on the second major surface of the polymeric substrate wherein the directly printable release coating comprises the reaction product of
- (i) from 50 to 95 weight percent of a vinyl functional monomer comprising the acrylic and methacrylic acid esters of a non-tertiary alcohol containing from 1 to 14 carbon atoms;
- (ii) from 5 to 50 weight percent of a chlorinated olefinic resin;
- (iii) from 0 to 30 weight percent of an amide-functional monomer;
- (iv) from 0.01 to 5 weight percent of a free radically polymerizable siloxane-containing component containing ##STR3## units.
