Abstract:

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.

Abstract:

Faceless PSA label constructions of this invention comprise a flexible substrate having a release surface, and a layer of pressure-sensitive adhesive disposed on the release surface. A nonblocking continuous film that, in combination with the pressure-sensitive adhesive is sufficiently self supporting, is disposed over a surface of the layer of pressure-sensitive adhesive to render the pressure-sensitive adhesive tack free. The continuous film is selected from the group of film-forming polymers consisting of polyamide resins, polyester resins, polyurethane resins, polyacrylate resins, vinyl acetate resins and mixtures thereof having a tensile strength of at least 200 psi, and a percent elongation of at least 50. The continuous film can be applied sequentially or simultaneously with the PSA. For purposes of simultaneous application it is desired that the continuous film be formed from a material having a hot melt viscosity that within a factor of about two times a hot melt viscosity for the PSA.

Abstract:

Prelaminate pressure-sensitive adhesive (PSA) constructions comprise, a first substrate, a coating or release material on a surface of the first substrate, a PSA layer disposed on the coating of release material, and a detackified layer (DL) disposed on a surface of the PSA layer to form a continuous film covering the PSA layer. In first and second embodiments of the construction the DL is activatable to form a tacky layer on top of the PSA layer for lamination with a second substrate. In a third embodiment, the DL includes constituents that when activated migrate into the PSA layer to expose the PSA layer tacky surface for lamination with a second substrate. The prelaminate PSA constructions are completely nonblocking to a minimum 24 hour blocking temperature of about 50Â C. at pressure of about 40 kilopascals, thereby allowing such prelaminate PSA construction to be collected, stored, and or transported before being laminated without adhesive interference occurring between continuous layers. The DL in each embodiment is activatable in less than five seconds to provide a tacky layer having a sufficient open tack time to permit lamination at less than about 100Â C.

Abstract:

Overlaminated faceless PSA label constructions of this invention comprise a low material cost, thin prelaminate PSA construction having a layer of pressure-sensitive material disposed on a release surface of a removable substrate, and a nonblocking continuous film disposed over a surface of the layer of pressure-sensitive adhesive to render the pressure-sensitive adhesive tack free. An optically transparent overlaminate film layer is disposed over the nonblocking continuous film, and a printed indicia is interposed between the overlaminate film layer and nonblocking continuous film. The prelaminate PSA construction does not include a conventional facestock formed from paper, cardboard or plastic, and is highly conformable.

The completed faceless PSA label construction is adapted to receive and retain printing or marking indicia directly onto a surface of the continuous film.
