Abstract: A multi-layered signage-lettering material containing a release or casting sheet layer with a pigmented display layer deposited on one side of the release sheet is described. The pigmented display layer is a coalesced film of at least one water-borne polymer of for example water-borne polyurethanes, water-borne acrylics, and mixtures thereof. Optionally, the coalesced film may be applied in multiple coats. The multi-layered material also includes an adhesive layer covering the surface of the pigmented display layer opposite the release sheet, and optionally, a removable protective layer covering the surface of the adhesive layer opposite the pigmented display layer. A method of fabricating the multi-layered signage-lettering material described above also is described. The method includes first depositing the pigmented display layer on the release or casting sheet.

Abstract: A water-evaporation process for making thin one-color plastic lettering, as used in sets for computer-cutting and application in spaced array. Water-based plastics, particularly urethanes and acrylics are used instead of polyvinyl chloride. These more flexible films are opaque, resulting from use of large amounts of water-dispersed pigments. After spreading, the water is evaporated, causing the spread mixture to coalesce into a thin tough well-pigmented opaque film. Films less than two mils thick may be formed, free from migratory plasticizers which might cause pigments to migrate or to damage adjacent the flanking layers of adhesives and release films. The water evaporation process, at only about 220.degree. F., requires minimal workplace or environmental safeguards compared to the use of solvent containing systems.
