Estimating the term…
Ink-imprintable release coating compositions are described which comprise a polymer comprising a polyurethane, a fluoroacrylate polymer or copolymer, or an addition cured or a condensation cured silicone polymer containing dispersed and/or emulsified resin particles, resin particle domains, or both, and, optionally, inorganic particles. The resin particles comprise resins which are different from the polymers and the resins comprise polyurethanes, polyamides, and polyureas. Ink-imprintable label, tape and stamp constructions also are described which comprise a plurality of contiguous labels, tapes or stamps in a roll or stacked sheet configuration without an independent release liner wherein the labels, tapes and stamps have a pressure-sensitive adhesive on the back surface and a cured ink-imprintable release coating on the face surface.
An ink-imprintable release coating composition comprising an aqueous emulsion or dispersion of (a) a condensation curable silicone polymer component, (b) resin particles, resin particle domains, or both, wherein the resin of (b) is selected from polyurethanes, polyamides and polyureas wherein the composition forms a release coating for a pressure sensitive adhesive when cured.
An ink-imprintable release coating composition comprising an aqueous emulsion or dispersion of (a) a condensation curable silicone polymer component, (b) resin particles, resin particle domains, or both, wherein the resin of (b) comprises polyurethane or polyamide, wherein the composition forms a release coating for a pressure sensitive adhesive when cured and the resin particles are capable of absorbing components of an ink or allowing components of an ink to penetrate the release coating.
An ink-imprintable release coating composition comprising an aqueous emulsion or dispersion of (a) from about 2% to about 90% by weight of a condensation curable silicone polymer component, (b) from about 5% to about 93% by weight of resin particles, resin particle domains, or both, and from about 5% to about 50% by weight of inorganic particles, wherein the resin of (b) is selected from polyurethanes, polyamides and polyureas wherein the composition forms a release coating for a pressure sensitive adhesive when cured.
