Abstract
A transparent, protective layer is disclosed for transfer from a release liner to a imaged substrate. The layer has a composition including vinyl resin, acrylic resin, optional plasticizer, and optional stabilizer. The layer is transferred at melt temperatures to the imaged substrate, followed by removal of the release liner. The melt temperatures do not harm the image or the substrate.
Claims7
A layer to cover and protect an imaged substrate, comprising:
- a transparent layer comprising vinyl chloride resin, acrylic resin, plasticizer, and stabilizer, wherein the transparent layer has a melt temperature sufficient to cause the transparent layer to melt on one major surface of the imaged substrate without harming the imaged substrate,
- wherein the amount of vinyl chloride resin ranges from about 49 to about 72 weight percent;
- the amount of acrylic resin ranges from about 9 to about 33 weight percent;
- the amount of plasticizer ranges from about 0 to about 33 weight percent;
- and wherein the mount of stabilizer ranges from about 0 to about 10 weight percent.
A composite comprising a transparent layer covering a durable, imaged substrate, wherein the transparent layer comprises a composition comprising vinyl chloride resin, acrylic resin, plasticizer, and stabilizer, wherein the composition has a melt temperature sufficient to cause the composition to melt on one major surface of the imaged substrate without harming the imaged substrate,
- wherein the amount of vinyl chloride resin ranges from about 49 to about 72 weight percent;
- the amount of acrylic resin ranges from about 9 to about 33 weight percent;
- the amount of plasticizer ranges from about 0 to about 33 weight percent;
- and wherein the amount of stabilizer ranges from about 0 to about 10 weight percent.
