Abstract: Coated sheet material having a support film which comprises a biaxially oriented, heat-set coextruded laminate formed from two or more polyester polymers, one layer of the laminate being highly crystalline and the coated layer being tough and non-crystalline. Coatings which normally adhere poorly to a biaxially oriented heat-set highly crystalline monofilm adhere firmly to the laminate. Coated sheet products include pressure-sensitive adhesive tape, lithographic printing plates, splicing tapes, and coated abrasives.

Abstract: Methods for bonding two substrates, one of which is polymeric, which comprise coating the surface of at least one substrate with an adhesive composition comprising a major component which is an adhesive for the first substrate and a minor disperse phase which is a solution of a polymer in a solvent for the polymeric substrate and contacting the coated surface of the one substrate with the surface of the other substrate, together with adhesive compositions useful for joining such substrates, laminates so formed, and articles comprised of such laminates.

Abstract: This invention relates to an improvement in a process for producing a cheese product wherein a cheese curd is extruded through a nozzle into a flexible, tubular mold, solidified to form a cheese product, and then removed from the flexible mold and the resulting product. The improvement is the use in the process of a "duplex type" mold constructed ofAn outer film laminate comprising a first film ply of cellophane having bonded to its outer surface a gas impermeable film having a gas transmission rate of less than about 10 cc/100 in..sup.2 /24 hour-atm.;A second film ply of biaxially oriented polypropylene bonded to the inner surface of said cellophane; andAn inner film comprising a film ply of biaxially oriented polypropylene.

Abstract: Laminar reflective platelets are made by coating a first synthetic resin lamina on a carrier web and providing release means such as a release coat to provide for release of the lamina. A metallic lamina is coated onto the synthetic resin lamina by vapor deposition in vacuum and a third optional synthetic resin lamina may then be coated onto the metal layer. Each of the three laminae has a thickness on the order of one to 3 millionths of an inch. The thus-coated web is immersed in a releasing solvent to activate the release means. The laminate is removed from the carrier by reason of solution or partial solution of the release coat or release means in the solvent. Removal may be aided by mechanical means such as brushing or scraping. The solvent is agitated to reduce the laminar platelets to final size. Laminar platelets thus formed have a thickness of from 0.5 to 5 millionths of an inch; each has a diffuse reflectance of from 75 to 95%, and 90 to 100% pass through a 300 mesh screen.

Abstract: A water-insoluble polymer comprising repeating units at least 1/3 of said repeating units having the formula: ##SPC1##Wherein R.sup.1 and R.sup.2 are hydrogen or alkyl and R.sup.3, R.sup.4 and R.sup.5 are alkyl groups wherein the total number of carbon atoms in R.sup.3, R.sup.4 and R.sup.5 is at least 12 and X.sup.-is an anion; is useful in dye mordant compositions in photographic elements. Preferred dye mordants comprise copolymers with styrene or methyl methacrylate.

Abstract: An improved method of finishing leather by transferring a finish coating, at least the outer stratum of which comprises a thermoplastic, adhesive acrylic polymer, from a release layer bearing the finish coating to the leather. The leather to be coated (which may be supported on an appropriate backing layer) and the release layer are pressed into a sandwich-like assembly with the concurrent application of sufficient heat and pressure to transfer substantially the entire finish coating to the surfaces of the leather and the backing layer juxtaposed therewith. Transfer of the finish coating is effected without the application of any adhesive material or "tie coat" prior to pressing the coating into contact with the leather, by virtue of the thermoplastic, adhesive characteristics of the acrylic finish coating per se.The method may be carried out batch-wise employing discrete backing and release layers for the transfer of finish coatings to individual leather pieces.
