An improved release system for heat transferable laminates wherein a transferable substrate which contains a design layer is transferred from a carrier web onto an article such as a plastic bottle or container upon application of heat and pressure. The carrier web includes a nonwax polyethylene layer. The improved release system includes a polyethylene layer portion of the carrier web in contact with and adhered to a nonwax transfer layer portion of the transferable substrate. The transferable substrate including the ink design layer transfers to the article upon application of heat to the carrier while the article contacts the laminate. The transferred substrate on the article is clear and exhibits improved scuff and abrasion resistance. The nonwax transfer layer portion of the transferable substrate advantageously contains an oil which becomes activated upon application of heat to promote release of the transferable substrate from the carrier web to the article.

An improved release coating for heat transferable laminates wherein an ink design layer is transferred from a carrier web onto an article such as a plastic or glass container upon application of heat and pressure. The improved release coating transfers with the ink design layer and forms an optically clear protective coating over the transferred ink design layer. The transferred release coating upon resolidification has an exceedingly high optical clarity, with no hazing, spotting, or halo discernible over the transferred ink design layer. The improved release coating incorporates a tackifying resin in a wax base. The wax base includes a montan wax and a crystalline wax such as paraffin wax. The wax base may also include a microcrystalline wax component. The preferred tackifying resin is selected from the polyterpene class.

An improved nonglossy release formulation for use in a heat transferable laminate wherein an ink design image is transferred from a carrier support to an article by application of heat to the carrier support. The improved release enhances anchorage of the ink design image while maintaining the required degree of release during transfer to an article. The improved release prevents image distortion during heat transfer to the article and provides the transferred image with a transparent, nonglossy, abrasion and corrosion resistant protective coating. The improved release is composed of a paraffin wax and a binder adhesion-promoting resin composed of a mono-olefin/vinylacetate/acrylic acid terpolymer or a mono-olefin/ethyl acrylate copolymer.

Heat transfer laminate

Chemically-resistant adhesives formed using non-hydrolyzable hard and soft resins. Chemically-resistant labels are provided by using the adhesive to adhere an image-bearing film of polyvinyl chloride to a protective film, and to a carrier. The labels are particularly resistant to acids and have a reduced tendency to shrink or distort when affixed to battery surfaces at elevated temperatures.

Chemically-resistant adhesives and labels

A method is disclosed for providing protective overcoatings to the surface of labels which are spaced apart and removably adhered to the release surface of a carrier web, the method comprising applying to the surface of the labels and to the surface of the carrier web exposed between labels a radiation-curable liquid composition, the composition wetting the surface of the labels to form a continuous film thereover, but not wetting the exposed release surface of the carrier web and forming thereover beads of liquid substantially unconnected to the continuous film over the labels, and thereafter exposing the films to a source of radiation sufficient to cure them to solvent resistant and abrasion resistant layers.
