Patent number: 6221466Abstract: A substrate with an organic undercoat as bonding layer for a printing medium to be deposited subsequently on the substrate in a printing process is such that the organic undercoat contains fine grained constituents of organic and/or inorganic substances, whereby the surface of the inorganic constituents is treated or provided with a coating of organic substances. Suitable inorganic constituents are e.g. highly dispersed silica, the surface of which is treated with a resin or a polymer. Suitable compositions for the organic undercoat layer on the substrate are organic coatings based on many commercially available organic coating materials with an addition of e.g. 0.3 to 20 wt. % silica. By adding highly dispersed silica to the undercoat the adhesion between the undercoat and the printing medium can be greatly improved, also in the case of laser printing methods with small thermal energy.Type: GrantFiled: October 29, 1998Date of Patent: April 24, 2001Assignee: Alusuisse Technology & Management Ltd.Inventors: Erwin Pasbrig, Dietrich Bubeck

Patent number: 6197144Abstract: Thermoplastic articles such as splash guards, in particular polyethylene splash guards, are decorated using a heat-activated decorative which includes a layer of a compatible thermoplastic adhesive which bonds an intermediate support sheet to the surface of the article. An indicia layer is then bonded to the support sheet. The support sheet is either a nonwoven web, a metal film, or a metalized cloth. The indicia layer can be an outer reflective or polymeric film bonded to the polyester nonwoven web using a compatible adhesive such as a linear alkyl polyester. If the support sheet is a metal film or metalized cloth, it can provide the indicia without a separate layer. However, a clear protective film may be required. This material remains tightly adhered to the surface of the article, even splash guards subjected to road conditions.Type: GrantFiled: December 9, 1999Date of Patent: March 6, 2001Inventor: John Mahn, Jr.
