Abstract: A dichroic polarizing film is made, for example, by, first combining polyvinyl alcohol and a second polymer, such as, polyvinyl pyrrolidone or a sulfonated polyester, in a solvent. The ratio of polyvinyl alcohol to second polymer is between about 5:1 to 100:1 by weight. The film is coated on a substrate, dried, and then stretched to orient at least a portion of the film. The film incorporates a dichroic dye material, such as iodine, to form a dichroic polarizer. This polarizer may be used in conjunction with a multilayer optical film, such as a reflective polarizer, to form an optical polarizer. The multilayer optical film may contain two or more sets of polyester films, where at least one of the sets is birefringent and orientable by stretching. The polyvinyl alcohol/second polymer film and the multilayer optical film may be simultaneously stretched to orient both polymer films.

Abstract: A tie layer film, comprising an admixture of polyvinyl alcohol and a water dispersible polyester, for bonding a support film to a topcoat layer. The preferred tie layer comprises a sulfopolyester, preferably including terephthalate groups or isophthalate groups. Most preferred are sulfopolyesters produced from ingredients comprising monomers selected from the group consisting of dimethyl 5-sodiosulfoisophthalate, dimethyl terephthalate, dimethyl isophthalate, ethylene glycol, and polycaprolactone diol. Alternatively the support film may be a layered film. In a preferred embodiment, the topcoat layer is formed from the same PVA material as the tie layer and the support film includes at least a portion of the same sulfopolyester as the tie layer. The tie layer is capable of maintaining the bond between the support film and the topcoat layer when heat stretched to a stretch ratio in the range of 2 times to 10 times its original dimension.

Abstract: An optical device includes a dichroic polarizer and a multilayer optical film, such as a reflective polarizer or mirror. The multilayer optical film is made using polymers which may allow for the simultaneous orientation of the dichroic and reflective polarizers. The multilayer optical film often contains a set of birefringent first layers and a set of second layers, which may have an isotropic index of refraction. The dichroic polarizers is a polyvinyl alcohol film with a dichroic dye. The multilayer optical film and dichroic polarizer can be stretched at temperatures of 130° C. or less to orient the two films without substantial cracking of the dichroic polarizer. When an optional second polymer is combined with the polyvinyl alcohol, the multilayer optical film and dichroic polarizer can be stretched at temperatures of about 160° C. without substantial cracking of the dichroic polarizer.

Abstract: Poly(vinyl chloride) resin compositions containing an ethylenically-unsaturated compound having carbonylamino or thiocarbonylamino groups. These compositions are readily convertible at low temperatures to crosslinked polymers and are radiation-curable to dimensionally stable articles and films that are clear and that do not exude oily materials.

Abstract: A method of transferring indicia from a first support base, such as a paper sheet, which is coated with a release agent, to a receiver surface, such as a wall or window. An adhesive surface is pressed against the first support base in order to transfer the indicia from the first support base to the adhesive surface. The adhesive bearing the indicia is then applied to a receiver surface to provide the receiver surface with a protected image. Preferably the indicia is a fused xerographic image and the release agent coated on the first support base is a unique radiation-curable fluorine-containing abherent coating composition.

Abstract: Radiation curable coating compositions for providing solvent-resistant abhesive coatings comprise polyfluorinated acrylates and methacrylates, polyethylenically unsaturated crosslinking agents and a film-forming organic polymer. The compositions can be used after radiation curing to render substrates oil, soil, and water repellent. The cured compositions have particular use as release coatings in image transfer systems wherein a fused xerographic image is transferred from the release coated surface, to another surface due to the particular characteristics of the coatings. Novel poly(fluorooxyalkylene)urethane acrylate compounds are also disclosed.

Abstract: The ability to withstand weathering by acrylic substrates having an abrasion resistant coating comprising a cured epoxy-terminated silane on the surface thereof is improved by using a particular primer composition between the coating and the substrate. The primer comprises a mixture of an acrylic polymer and cellulose esters of carboxylic acids.
