Patent number: 7067232Abstract: 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.Type: GrantFiled: February 5, 2003Date of Patent: June 27, 2006Assignee: Alcoa Inc.Inventors: David S. Bennett, Sallie L. Blake, Daniel L. Serafin, Jean Ann Skiles, Robert E. Bombalski, Clinton S. Zediak, Gary A. Nitowski, Joseph D. Guthrie

Patent number: 6783836Abstract: A lithographic sheet product having a substrate with a roll textured surface covered by a pretreatment layer. The pretreatment layer enhances adhesion of a printing composition to the sheet product and is composed of a polymer selected from the group consisting of polymers of acrylic acid, polymers of methacrylic acid, an organophosphorous polymer and copolymers of an organophosphorous compound and acrylic acid or methacrylic acid. Dopant particles of alumina, silica, titanium dioxide or a black dye or pigment may be added to the pretreatment layer to reduce the gloss and reflectance of the pretreatment layer in a printing process. Etching of the substrate also reduces gloss and reflectance.Type: GrantFiled: August 29, 2001Date of Patent: August 31, 2004Assignee: Alcoa Inc.Inventors: David Bennett, Sallie L. Blake, Robert E. Bombalski, Joseph D. Guthrie, Daniel L. Serafin

Patent number: 6715420Abstract: A printing plate for computer-to plate lithography having a metal substrate with an anodized surface portion. The anodized surface portion has a porous texture in which a radiation-absorbing composition, preferably a black dye, is deposited. The surface portion with the radiation-absorbing composition is covered with a hydrophilic polymer or a sealant both. Upon exposure to laser radiation, the underlying oleophilic anodized surface portion containing the radiation-absorbing composition is revealed. Alternatively, laser radiation of the polymer composition may cause the affinity of the polymer for water and ink to change so that an irradiated portion of the polymer becomes oleophilic while the non-irradiated portion remains hydrophilic.Type: GrantFiled: July 1, 2002Date of Patent: April 6, 2004Assignee: Alcoa Inc.Inventors: Sallie L. Blake, Albert L. Askin, Robert E. Bombalski, Daniel L. Serafin

Patent number: 6673519Abstract: 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: GrantFiled: July 14, 2001Date of Patent: January 6, 2004Assignee: Alcoa Inc.Inventors: David S. Bennett, Sallie L. Blake, Robert E. Bombalski, Daniel L. Serafin, Jean Ann Skiles

Patent number: 6631679Abstract: 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: GrantFiled: February 8, 2002Date of Patent: October 14, 2003Assignee: Alcoa Inc.Inventors: David S. Bennett, Sallie L. Blake, Robert E. Bombalski, Kenneth A. Bowman, Joseph D. Guthrie, Thomas L. Levendusky, Daniel L. Serafin, Jean Ann Skiles

Patent number: 6560845Abstract: A prefinished curved reflector suitable for use in recessed lighting, downlighting, head lamps, and tail lamps is made from metal sheet, preferably an aluminum alloy sheet. An outer surface of the metal sheet is either anodized, laminated, or polymer coated to provide desired appearance and performance. Surprisingly, the metal sheet retains its reflectivity and resistance to corrosion even after deformation into a curved reflector.Type: GrantFiled: March 21, 2000Date of Patent: May 13, 2003Assignee: Alcoa Inc.Inventors: Daniel L.
