Patent number: 4925779Abstract: A photo negative strip including a sequence of individual photo frames is protected by laminating two slightly narrower strips of transparent protective film onto the opposed surfaces of the photo strip; each protective strip is removably secured to the photo strip by two edge stripes of a pressure sensitive releasable adhesive. The adhesive stripes covers the sprocket holes near the edges of the photo strip, but edge portions of the photo strip are left, uncovered by either protective film, along both outer edges of the photo strip. The preferred protective film is of biaxially oriented polystyrene.Type: GrantFiled: December 22, 1988Date of Patent: May 15, 1990Assignee: Qualex, Inc.Inventors: Stanislaw A. Policht, Gerard Vernice

Patent number: 4902594Abstract: A photoimaged article having a protected image composed of a colored image on a support; and a thin, transparent, flexible, nonself supporting, protective layer on the surface of the image. The layer is substantially nontacky at room temperature, and has at least a major amount based on the weight of the layer of one or more thermoplastic resins of a vinyl acetal, vinyl chloride, or acrylic polymer or copolymer having a Tg of from about 35.degree. C. to about 110.degree. C. The layer is capable of being adhesively transferred directly to the image when the layer is first applied on the release surface of a temporary support, and the image and protective layer are laminated together under pressure at temperatures of between about 60.degree. C. to about 180.degree. C. with subsequent removal of the temporary support. The side of said layer opposite to the image is free from additional layers. The adhesive layer is one which does no cohesively block at temperatures ofabout 50.degree. or less.Type: GrantFiled: October 21, 1988Date of Patent: February 20, 1990Assignee: Hoechst Celanese CorporationInventor: Stephan J.

Patent number: 4824762Abstract: The improvement of the invention consists in the use of a specific ether compound, e.g., diethyleneglycol monomethyl, monoethyl and monobutyl ethers, dipropyleneglycol monomethyl and monoethyl ethers, triethyleneglycol monomethyl and monoethyl ethers and tripropyleneglycol monomethyl ether, as a rinse solvent for a substrate from which the pattern photoresist layer has been removed with a remover solution in the photolithographic processing of semiconductor devices. The rinse solvent is free from the problems in the toxicity to human body and environment pollution relative to waste disposal as well as the danger of fire. The rinse solvent is versatile to be applicable to both of the negative- and positive-working photoresist compositions. Further advantages are obtained by adding an aliphatic amine compound to the rinse solvent.Type: GrantFiled: June 26, 1987Date of Patent: April 25, 1989Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Masakazu Kobayashi, Shingo Asaumi, Hatsuyuki Tanaka
