Publication number: 20020121204Abstract: A process for making printing plate material suitable for imaging by laser radiation. A metal substrate is electrocoated in a bath containing a polymeric resin and laser-sensitive particles, thereby depositing a laser ablatable layer on a principal surface of the metal substrate. In one embodiment, the laser-ablatable layer is treated with a corona discharge for a time sufficient to render the layer non-ink wettable. In other preferred embodiments, the laser-ablatable layer is overcoated with an overlayer such as a non-ink wettable silicone layer or a water-wettable layer comprising an organophosphorus polymer, preferably a copolymer of acrylic acid and vinylphosphonic acid.Type: ApplicationFiled: February 8, 2002Publication date: September 5, 2002Inventors: David S. Bennett, Sallie L. Blake, Robert E. Bombalski, Kenneth A. Bowman, Joseph D. Guthrie, Thomas L. Levendusky, Daniel L. Serafin, Jean Ann Skiles

Publication number: 20020034707Abstract: A printing plate for computer-to plate lithography having a laser-ablatable member supported by a substrate. At least one portion of the laser-ablatable member is formed form an acrylic polymer containing laser-sensitive particles. The laser-sensitive particles absorb imaging radiation and cause the portion of the laser-ablatable member containing the laser sensitive particles and any overlying layers to be ablated. Alternatively, the printing plate may include a printing member with an initial affinity for a printing fluid that changes to another affinity to printing fluid upon treatment with radiation.Type: ApplicationFiled: July 14, 2001Publication date: March 21, 2002Inventors: David S.

Patent number: 5985046Abstract: A process for making an aluminum alloy lighting sheet product having a reflective surface protected by a UV-stable polymer coating. An aluminum alloy sheet is chemically brightened in an aqueous acidic solution, conversion coated, and then coated with a UV-stable polymer. Alternatively, an aluminum alloy sheet is chemically etched in an aqueous alkaline solution, conversion coated, and then coated with a UV-stable polymer. The UV-stable polymer may be clear or it may contain about 0.5-10 wt. % amorphous silica particles and polytetrafluoroethylene particles. In another embodiment, an aluminum alloy sheet surface is cleaned, chemically conversion coated and then coated with a coating composition containing a UV-stable polymer and 0.5-10 wt. % silica particles and polytetrafluoroethylene particles, both having an average size of about 0.5-5 microns.Type: GrantFiled: March 10, 1998Date of Patent: November 16, 1999Assignee: Aluminum Company of AmericanInventors: Daniel L.

Patent number: 5795647Abstract: A printing plate is made by coating a metal substrate with a polymer layer having an outer surface, coating the polymer layer with solid particles having an average particle size of less than about 30 microns, and compressing the solid particles so that most of them are below the polymer layer outer surface. The solid particles are preferably alpha-alumina particles having an average size of about 1-10 microns. The printing plate has improved wear resistance.Type: GrantFiled: September 11, 1996Date of Patent: August 18, 1998Assignee: Aluminum Company of AmericaInventors: Edward C. Robinson, Robert E.

Patent number: 5637404Abstract: A strip of highly reflective aluminum protected by a conversion coating and a light-permeable fluoropolymer coating which is non-adhesively interstitially mechanically bonded to the microscopic irregularities of the conversion coated surface. The highly reflective strip may be substituted for polished stainless steel and/or bi-metal and used under aggressive conditions for a prolonged period without deleteriously affecting the initial D/I (distinctness of reflected image) of the shaped strip. The strip of arbitrary length may be shaped in rolling dies so that at least a portion of the strip has a radius of less than 10 mm without damaging or separating the fluoropolymer coating. The specific steps of the claimed process require starting with a bright-rolled clean strip which is conversion coated to carry a thin metal compound coating. The reflective conversion coated surface is coated with the fluoropolymer while maintaining at least 80% D/I.Type: GrantFiled: October 18, 1995Date of Patent: June 10, 1997Assignee: Aluminum Company of AmericaInventors: Robert E. Bombalski, Daniel L. Serafin

Patent number: 5478414Abstract: A strip of gray reflective aluminum protected by a conversion coating and a light-permeable fluoropolymer coating which is non-adhesively interstitially mechanically bonded to the microscopic irregularities of the conversion coated surface. The highly reflective strip may be substituted for polished stainless steel and/or bi-metal and used under comparably aggressive conditions for a prolonged period without deleteriously affecting the initial D/I (distinctness of reflected image) of the shaped strip. The strip of arbitrary length may be shaped in rolling dies so that at least a portion of the strip has a radius of less than 10 mm without damaging or separating the fluoropolymer coating. The specific steps of the claimed process require starting with a bright-rolled clean strip which is conversion coated to carry a thin metal compound coating. After rinsing and drying, the reflective surface is coated with the fluoropolymer while maintaining at least 80% D/I.Type: GrantFiled: January 21, 1994Date of Patent: December 26, 1995Assignee: Aluminum Company of AmericaInventors: Frank A.

Patent number: 5290424Abstract: A shaped strip of highly reflective aluminum protected by an anodic oxide coating and a light-permeable fluoropolymer coating which is non-adhesively interstitially mechanically bonded to the microscopic irregularities of the anodic oxide surface. There is no adhesive used to obtain chain entanglement. The highly reflective strip may be substituted for polished stainless steel and/or bi-metal and used under comparably aggressive conditions for a prolonged period without deleteriously affecting the initial D/I (distinctness of reflected image) of the shaped strip. The strip of arbitrary length is shaped in rolling dies so that at least a portion of the strip has a radius of less than 10 mm without damaging or separating the fluoropolymer coating. The specific steps of the claimed process require starting with a clean strip which is brightened to a nearmirror-like finish, then treated to carry a thin porous aluminum oxide coating in a phosphoric acid bath under direct current (DC).Type: GrantFiled: January 31, 1992Date of Patent: March 1, 1994Assignee: Aluminum Company of AmericaInventors: Frank A.
