Patent number: 5759683Abstract: A holographic article and method for forming permits the party producing the final document to print the holographic image directly on the final document thereby permitting such party to retain and maintain control of its own embossing shim on which the hologram has been formed and which is utilized for embossing the holographic image on the document. A film upon which a holographic image can be directly stamped upon the final document includes a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons, a lacquer coating having a thickness in the range of 0.5 microns to 3 microns and a heat activatible adhesive. The metal layer lacquer coating and heat activatible adhesive are caused to be adhered to the substrate forming the final document during a stamping operation which releases said metal layer, lacquer coating and heat activatible adhesive from a plastic carrier film to which had initially been applied.Type: GrantFiled: June 27, 1995Date of Patent: June 2, 1998Assignee: NovaVision, Inc.Inventor: David R. Boswell

Patent number: 5712003Abstract: Provided is a blow-molded article which can be readily formed with good Gloss and with substantially no surface unevenness, even without application of surface coating, and which can be used as a finished product without further treatment. The blow-molded article has a base layer and a surface layer. The base layer is formed from a thermoplastic resin material having a melt index (MI) of about 0.05-2.0 and a flexural modulus of 1,470 MPa (15,000 kgf/cm.sup.2) or more. The surface layer is formed from a colored or transparent thermoplastic resin material having an MI of about 1-30 provided that it is higher than that of the base layer, and excellent weather resistance. The thermoplastic resins used to form the base and surface layers should be resins of the same family.Type: GrantFiled: October 20, 1995Date of Patent: January 27, 1998Assignee: Toyoda Gosei Co., Ltd.Inventors: Kiyoshi Suenaga, Syojirou Miyamoto, Koichi Ogiso

Patent number: 5688598Abstract: A thermosetting, organic solvent-based, primer coating composition for protecting metal surfaces which includes a solvent solution of: (a) a hydroxy-functional polyester resin; (b) a thermosetting acrylic resin; (c) a hydroxy-terminal polybutadiene resin, a hydroxy-terminal epoxidized polybutadiene resin, or mixtures thereof; (d) a blocked isocyanate crosslinker including at least one dimethyl pyrazole blocked isocyanate; (e) an aminoplast crosslinker including at least one melamine-formaldehyde condensate; (f) a catalyst; and, (g) a pigment. The primer exhibits excellent flexibility after curing to allow the primer to be coil coated onto metals as a thicker film and to have the metal subsequently formed without film fracture or loss of adhesion.Type: GrantFiled: June 28, 1996Date of Patent: November 18, 1997Assignee: Morton International, Inc.Inventors: Mitchell T. Keck, Ronald J. Lewarchik, Jack C. Allman
