Disclosed herein is a multilayer silicone release surface comprising a backing, a support layer on the backing, and a silicone layer of the support layer. The various layers of the multilayer release surface are deposited substantially simultaneously, as for example by a dual die or using curtain coating techniques.

Method for forming multilayer release liners

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.

Ink-imprintable release coatings, and pressure sensitive adhesive constructions

Ink-imprintable compositions comprise a reaction product of a mixed emulsion containing a carboxylic acid terminated polydimethylsiloxane, or an isocyanate terminated polydimethylsiloxane, a hydrophilic isocyanate reactive agent, a polyisocyanate, and at least one dihydroxy terminated oligomer. Ink-imprintable stamp constructions also comprise a plurality of contiguous stamps in a roll or stacked sheet configuration without an independent release liner wherein the stamps have a pressure-sensitive adhesive on the back surface of the stamps and the above ink-imprintable release coating on the face surface of the stamps.
