Estimating the term…
An abrasion resistant coated film including a polyester film coated with a highly crosslinkable melamine coating with a crosslinking density of greater than about 50% and less than about 100%, wherein the coating is cured after transverse stretching and heat setting the film, a melamine coating having a crosslinking density between about 50% and about 100% containing between about 0.01% by weight and about 1.0% by weight of a colloidal particle selected from the group consisting of silica, TiO2, graphite and blends thereof, and a method of producing an abrasion resistant coated film including stretching a polyester film in the machine direction to form a uniaxially oriented film, applying a coating of highly crosslinkable melamine with a crosslinking density between about 50% and about 100% onto the uniaxially oriented film, heating and stretching the coated film in the transverse direction and curing the coating on the coated film.
A biaxially oriented print receptive and abrasion resistant coated film comprising a polyester film and a coating consisting essentially of hexamethoxymethyl melamine having a methylation content of greater than about 30% and a crosslinking density of greater than about 50% and less than about 100% coated on the polyester layer, wherein the coating is cured after transverse stretching and heat setting the film.
