Abstract
A web (14) and associated method for applying lettering to a fabric substrate (12), having a substantially transparent carrier sheet (16) consisting essentially of a plastic film, or layer (18) of pigmented thermoplastic or thermoset material coated on and peelable from the carrier sheet, and an adhesive layer (20) for bonding the pigmented layer to a water repellant substrate such as nylon. In accordance with one aspect of the invention, the pigmented thermoplastic material is polyurethane and the adhesive system is a composite layer of a solvent-based urethane adhesive coating (26) on the pigmented layer and a water-based urethane adhesive coating (28) on the solvent-based adhesive coating. The water-based coating preferably includes cross-linking agents.
