Patent number: 5312646Abstract: Photographic materials, such as films and papers, include a support and coatings on the support. The coatings often contain hardeners which cause gelation cross links in the binder in the coating. The extent to which the cross-links have formed at the time of processing of the film or paper affects the appearance of the image produced by processing. Conventionally the cross-links have been allowed to form with time in normal atmospheric conditions. According to the invention, the formation of the cross links is accelerated to substantial completion by a process including incubating the material at a temperature above the glass transition temperature of the coating and below the melting point of the coating in an atmosphere having a relative humidity which causes a moisture content of the coating of 0.1 to 0.25 for a period of time sufficient to substantially complete the hardening, that is, the formation of the cross-links.Type: GrantFiled: February 27, 1991Date of Patent: May 17, 1994Assignee: Eastman Kodak CompanyInventors: Eugene H.

Patent number: 4546011Abstract: A web of crepe paper, thin plastic foil or like material convoluted into a roll has an outer side which is provided with a continuous coat of adhesive. Transversely extending, uniformly spaced weakened portion in the form of perforations or slits are formed in the web, and layers of a material which does not adhere to the adhesive are applied to the web. Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions. The roll can be used for the cleaning of garments or for analogous purposes and can be made in an apparatus wherein the application of layers of non-adherent material precedes or follows the making of weakened portions.Type: GrantFiled: December 7, 1983Date of Patent: October 8, 1985Assignee: Gebrauchs Gerate GmbHInventor: Emil Wolfrum

Patent number: 4539227Abstract: A sufficiently thick gliding layer is produced on the recording surface of a record carrier of the type comprising an aluminum layer applied over a lacquer layer coated on a support layer. The back surface of the support layer is also coated with a lacquer layer. A fatty acid or a mixture of fatty acids is admixed with one of the two lacquer layers and a metal-diketone or a metal-keto-ester is admixed with the other lacquer layer in approximately in a stoichiometric ratio to the fatty acid. Following the coating of the material with aluminum in a vacuum, the record carrier material is wound into a roll, and stored.Type: GrantFiled: January 18, 1984Date of Patent: September 3, 1985Assignee: International Business Machines CorporationInventors: Marian Briska, Dietrich J.

Patent number: 4432301Abstract: A method for applying adhesive to a printed paper commercial garment-making rolled pattern marker includes spraying the back (upward facing) side of the marker with a fast-drying adhesive and as the upper surface of the applied adhesive becomes tacky, rolling the marker upon itself. The adhesive remains tacky on the rolled-up marker for a relatively long time, so that it may be used later, when desired, by simply unrolling it tacky side down on top of the fabric to be cut. Apparatus for applying the adhesive includes a variable speed paper-handling mechanism which transfers the marker along a path from an upper feed roll, forward and downward to a take-up roll, and a multiple-nozzle airless spraying mechanism which applies the adhesive to the back side of the marker. The application and paper travel rates are such that the outer surface of the adhesive becomes tacky before the marker is rolled upon itself on the take-up roll.Type: GrantFiled: August 21, 1980Date of Patent: February 21, 1984Inventor: Nelson P. Diesel

Patent number: 4405678Abstract: The use of organic materials containing carbonyl groups (which are not part of carboxyl group), phenoxy groups, ester groups, or alcohol groups over vapor deposited metal layers improves their mar resistance. These organic materials can improve the properties of the metal layer when used in photoresist imaging films.Type: GrantFiled: February 22, 1982Date of Patent: September 20, 1983Assignee: Minnesota Mining and Manufacturing CompanyInventors: Edward J. Downing, Richard S. Fisch

Patent number: 4393117Abstract: An improved process for coating a pressure sensitive adhesive upon a differential-release-type substrate and the products produced thereby. The coating procedure involves using a solvent-free hot-melt adhesive coating system and a short period of exposure to the environment of the web being processed between the time the web is coated with adhesive and spooled for packaging.Type: GrantFiled: July 13, 1981Date of Patent: July 12, 1983Assignee: Ludlow CorporationInventors: George O. Stricker, Karl H. Teumer, Ronald C. Groenendal

Patent number: 4381322Abstract: To reduce scratches on the aluminum-covered front surface of a record carrier substrate having a back surface covered with a nitrocellulose lacquer, 0.1 to 2 percent by weight of a fatty acid, as referred to the weight of the wet lacquer, is added to the last applied layer of lacquer. When the record carrier is wound into a roll, the aluminum layer contacts and reacts with the fatty acid forming a sliding layer.Type: GrantFiled: September 21, 1981Date of Patent: April 26, 1983Assignee: International Business Machines CorporationInventors: Dietrich J.

Patent number: 4358067Abstract: A method for producing a pressure-sensitive copying sheet which comprises winding the pressure-sensitive copying sheet having a microcapsule coating film comprising microcapsules having an average particle size of 3-8 microns and a hydrophobic oil containing 3-6% by weight of a color former at 35 kg/m or less, and while winding continuously reducing the winding tension to an amount of about 40 to 70% of the initial winding tension as the roll diameter increases. An embodiment is also disclosed where said coating contains an antismudging and/or a covering agent and the initial winding tension is 70 kg/m or less.Type: GrantFiled: December 19, 1978Date of Patent: November 9, 1982Assignee: Fuji Photo Film Co., Ltd.Inventors: Masao Kanda, Makoto Yoshida

Patent number: 4331727Abstract: An adhesive transfer device is disclosed for use in preparing mock-ups of newspaper pages, advertising and the like, by supplying adhesive to the back of the material to be secured to the mock-up. The device includes a substrate carrier having a pair of opposed surfaces and a layer of release coating material coated on each of these faces. An adhesive layer is placed on one of the release coating layers and the substrate is rolled into a roll. This roll is easily unrolled when it is desired to use the adhesive and the adhesive face will then be exposed so that it can be contacted with the specimen, photograph or other article to be placed on the mock-up page. After this contact, when the specimen is pulled from the substrate, the adhesive coating is released from the substrate, remains on the photo, and serves to secure the photo or the like to the mock-up sheet.Type: GrantFiled: October 7, 1977Date of Patent: May 25, 1982Inventor: Stanley Maas
