Abstract
Abstract An improved decal and method of decal manufacture includes a base sheet of polyethylene (polymeric) type material with a urethane (polymeric) high solids content carrier layer in the shape of the decal printed thereon. The graphics for the decal are printed on the carrier layer and a high tack adhesive is then overprinted on the ink layers forming the completed decal. The decal is applied to a surface and the base sheet is separated from the applied decal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
A pressure sensitive, dry transfer decal comprising, in combination: a base sheet; a printed carrier coat of cross linked polymeric material on the base sheet having an extent of coverage on the base sheet of a complete image on the base sheet, said carrier coat being releasable from the base sheet; at least one layer of printed ink on the carrier coat defining at least a portion of the image; a second coat of cross linked polymeric material over the printed ink layer; and a pressure sensitive adhesive layer over said second coat and carrier coat and substantially coextensive with the carrier coat for pressure application of the decal to a surface.
