Abstract: A silicone release film including an oriented polyester film having a coating thereon in an amount sufficient to act as a silicone release film. The aqueous coating comprises glycidoxy silane and an aqueous based thermosetting silicone release composition. The minimum amount of glycidoxy silane present in the coating is at least 1.0% by weight of the silicone solids. Typical glycidoxy silanes are glycidoxypropyltrimethoxysilane or glycidoxypropyltriethoxysilane. A process for coating a polyester film with a silicone coating is also disclosed, where the coating occurs in-line, during the manufacturing process for the film before it is heat-set.

Abstract: The present invention describes a process for priming a polymeric film with a primer coating composition and overcoating with a silicone release coating. Silicone release films are well known and serve as temporary supports for an adhesive or tacky surface such as for labels, pressure sensitive tape, etc. The primer coating composition, before dilution with water, comprises from about 25 to 75% by weight of a glycidoxy silane and from about 75 to 25% by weight of a copolyester. The copolyester comprises from about 40 to 98 mol percent isophthalic acid; from about 0 to about 50 mol percent of at least one aliphatic dicarboxylic acid; from about 2 to about 20 mol percent of at least one sulfonate group attached to a dicarboxylic nucleus; and about 100 mol percent of glycol having from about 2 to 11 carbon atoms. Typical glycidoxy silanes that can be employed in the primer coating composition include glycidoxypropyltrimethoxysilane.

Abstract: Oriented polyester film primer coated-in-line with hydrolyzed aminosilane is disclosed. The aminosilanes in the unhydrolyzed state have the formula:(R.sup.1).sub.a Si(R.sup.2).sub.b (R.sup.3).sub.cwherein R.sup.1 is a functional group with at least one primary amino group; R.sup.2 is a hydrolyzeable group such as a lower alkoxy group, an acetoxy group, or a halide; and R.sup.3 is a nonreactive, nonhydrolyzeable group such as a lower alkyl or a phenyl group; with (a) being greater than or equal to 1; (b) being greater than or equal to 1; (c) being greater than or equal to zero; and with a+b+c=4. The hydrolyzed aminosilane is applied to the film as an aqueous solution at any suitable stage during manufacture of the film, i.e, before, or during, or after the stretching operation, but prior to heat setting the film. The resultant primed polyester film is found to exhibit excellent adhesion to other polymeric materials.

Abstract: A substantially wrinkle-free, high modulus, thermoplastic film having at least one compound curve is disclosed. The substantially wrinkle-free film may form a part of a laminate which itself has utility in automotive glazing applications.An improved lamination process is also disclosed for the production of non-planar laminates from planar sheets of heat-shrinkable films through the use of a negative image mold of the non-planar article to be laminated. Heat-shrinkable films which may be used in the practice of the invention include polyester films, polyolefin films, polyamide films, polyurethane films, polycarbonate films, polyvinylchloride films, and polystyrenic films.The method is applicable to a wide range of non-planar articles and is particularly suitable to articles having at least one compound curve forming at least part of its surface. The improved lamination process of the present invention has specific utility in the manufacture of automotive glazing products such as windshields and rear windows.

Abstract: An oriented polyester film coated on one or both sides with a crosslinked vinyl acetate polymer composition which renders the polyester film surface receptive to additional reprographic or matte coatings applied thereto, and to film containing the reclamation product of such coated film.

Abstract: A prime coated oriented polyester film material is disclosed wherein the primer coating consists essentially of a crosslinked copolymer containing at least about 50% by weight of acrylic and/or methacrylic monomers and from about 1% to 15% by weight of a comonomer capable of inter-molecular crosslinking upon the application of heat, and from 0 to about 49% by weight of one or more halogen-free mono-ethylenically unsaturated monomers copolymerizable therewith.The priming layer may be applied to the polyester film at any suitable stage during manufacture of the film, i.e., before or during the stretching operations, and is crosslinked after application by means of heat. The resultant primed polyester film is found to provide excellent adhesion to many organic solvent based coatings subsequently applied thereto, and to be reclaimable when reprocessed during the manufacture of polyester film without giving rise to significant or intolerable discoloration or degradation of the film.

Abstract: A pesticidal composition containing as an active ingredient a polychlorinated naphthalene ester or an acid chloride obtained from a one-step method of preparing nuclearly chlorinated naphthalene esters. The active ingredient is selected from the group consisting of 1,4-dichloro-2,6-dicarbomethoxynaphthalene, 1,4,7,8-tetrachloro-2,6-dicarbomethoxynaphthalene, 1,3,4,7,8-pentachloro-2,6-dicarbomethoxynaphthalene, hexachloro-alpha-methyl naphthate 3,4,5,7-tetrachloro-alpha-methyl naphthoate, 2,4,5,6,8-pentachloro-alpha-methyl naphthoate, 2,3,4,6,7,8-hexachloro-alpha-methyl naphthoate, 1,3,4,7,8-pentachloro-beta-methyl naphthoate and heptachloro-alpha naphthalene carbonyl chloride.

Abstract: A direct, essentially one-step method of preparing nuclearly chlorinated naphthalene esters which comprises forming a reaction mixture consisting essentially of a mono- or dicarboalkoxy substituted naphthalene, a chlorinated organic solvent having from 1 to 4 carbon atoms and a chlorination catalyst, heating the reaction mixture, and passing molecular chlorine into the mixture. The extent of the chlorination of the naphthalene mono- or diester can be controlled by varying the solvent employed, the amount of chlorine added and the reaction time. A number of unreported polychlorinated naphthalene esters and an acid chloride are obtained directly by the method. The esters can be used in the production of coloring materials, plastics and insecticides.
