Abstract:
1. A coating method for forming an acrylic film comprising the steps of: (a) applying a liquid acrylic/solvent mixture onto a moving, discontinuous carrier substrate; and (b) drying the liquid acrylic/solvent mixture to less than 5% solvent so as to substantially remove the solvent yielding a composite of an acrylic film adhered to the discontinuous carrier substrate, winding the composite into at least one roll before the acrylic sheet is peeled from the discontinuous carrier substrate, the acrylic film being releasably adhered to the discontinuous carrier substrate thereby allowing the acrylic film to be peeled from the discontinuous carrier substrate, wherein the acrylic film has a thickness in the range of from about 1 to about 500 μm, the acrylic film has an in-plane retardation that is less than 5 nm, and the acrylic film is adhered to the carrier substrate with an adhesive strength of less than about 250 N/m further comprising the step of: delivering the composite to a user of the acrylic film, the carrier substrate acting as a protective support for the acrylic film prior to the acrylic film being separated from the substrate carrier, cuffing the composite and then removing the acrylic film.
