Abrasion-resistant transfer laminating sheet material

Claim 1

A multilayered sheet of material for providing a transferrable abrasion-resistant coating capable of lamination comprising in sequence a. a strippable carrier substrate; b. a flexible abrasion-resistant coating on the said carrier substrate wherein said coating is from 1.27 to 25.4 μm thick and comprises a polymer which has at most 30% haze according to ASTM D 968-51 using 1 liter of sand in 10-11 seconds, said polymer having (1) 25 to 60% by weight units derived from precondensed monomers which are epoxy-terminated silanes of the formulae ##STR4## wherein R is selected from alkylene of 1 to 10 carbon atoms and --CH 2 --O--(CH 2 ) m , wherein m is 1 to 5, n is 1, and R' is selected from alkyl of 1 to 8 carbon atoms, (2) 40 to 75% by weight units derived from epoxidized organic compounds other than epoxy silanes, and (3) from 0.1 to 5% by weight of an antioxidant; c. a coated pressure-sensitive adhesive layer which is from 0.5 to 13 μm thick; and d. a strippable release sheet comprised of a liner substrate with a low adhesion backsize; wherein the release force between the abrasion-resistant coating, peeled at a 180° angle, and the carrier substrate is <25 g/2.54 cm width, and the release force between the release sheet, peeled at a 180° angle, and the pressure-sensitive adhesive coating is <10 g/2.54 cm width.
