Abstract

A self-wound decorative dry paint transfer laminate includes a layer of dry paint, a pressure-sensitive adhesive layer on one side of the dry paint layer, and a release liner in releasable contact with the dry paint layer on a side opposite from the pressure-sensitive adhesive. The release liner has a matte release coat layer that contacts the dry paint layer. The matte release coat releasably adheres to the dry paint layer to provide a protective function but also to transfer a decorative matte finish to the dry paint layer when the release liner is removed from the dry paint layer. The opposite side of the release liner has an adhesive release coat that contacts the pressure-sensitive adhesive when the laminate is in a self-wound form.

Dependent claims

A self-wound decorative dry paint transfer laminate comprising a layer of dry paint, a pressure-sensitive adhesive layer on one side of the dry paint layer adapted for room temperature adhesion to a substrate surface, and a release liner in releasable contact with the dry paint layer on a side opposite from the pressure-sensitive adhesive, one side of the release liner having bonded thereto a matte release coat layer that contacts the dry paint layer, the matte release coat layer releasably adhering to the dry paint layer but adapted to transfer a matte surface finish to the dry paint layer when the release liner is removed from the dry paint layer, the dry paint layer comprising a pigmented color coat layer and a transparent outer clear coat layer bonded to the color coat and in contact with the matte release coat layer on the release liner, the matte surface being transferred to the transparent outer clear coat layer, an opposite side of the release liner having an adhesive release coat layer that contacts the pressure-sensitive adhesive when the laminate is in a self-wound form, the adhesive release coat layer preferentially releasing the liner from the pressure-sensitive adhesive when the laminate is unwound while the liner maintains adhesion to the matte release coat layer, the pressure-sensitive adhesive comprising a crosslinked acrylic resinous material, the matte release coat layer having a micro-roughened surface for transferring a matte surface finish to the dry paint layer at room temperature with a surface gloss of less than about 35% at 85°.

A self-wound multi-layer laminate for applying a layer of color to a substrate surface, the laminate comprising:

a dry paint layer comprising a color layer which includes a binder and a pigment, the dry paint layer having an upper surface and a lower surface,
a pressure-sensitive adhesive layer overlying the upper surface of the dry paint layer and adapted for adhering the laminate to a substrate surface at room temperature;
a release liner overlying the lower surface of the dry paint layer, the release liner having a dry paint release coat releasably adhered to the lower surface of the dry paint layer, and an adhesive release coat layer on a side of the release liner opposite from the dry paint layer, the release liner and the dry paint release coat removable from the dry paint layer at room temperature,
the dry paint release coat transferring a controlled surface finish to an exposed surface of the dry paint layer when the pressure-sensitive adhesive layer adheres the laminate to the substrate surface under application of pressure and the release liner is peeled away from the dry paint layer,
the laminate adapted for being self-wound into a roll with the pressure-sensitive adhesive layer in contact with the adhesive release coat layer,
the adhesive release coat layer and the pressure-sensitive adhesive layer having an unwind release force between them which is lower than a carrier release force between the dry paint release coat and the dry paint layer, such that the adhesive release coat preferentially releases the liner from contact with the pressure-sensitive adhesive layer when unwinding the laminate from its roll form, while the dry paint release coat maintains contact with the dry paint layer when the laminate is being unwound from its roll form,
in which the pressure-sensitive adhesive is selected from the group consisting of a crosslinked acrylic resinous material, an internally crosslinked acrylic emulsion, and a crosslinked copolymer emulsion of butyl acrylate and ethyl hexyl acrylate.
