20090260531 | ALUMINUM ALLOY PLATE FOR LITHOGRAPHIC PRINTING PLATE, LITHOGRAPHIC PRINTING PLATE SUPPORT, PRESENSITIZED PLATE, METHOD OF MANUFACTURING ALUMINUM ALLOY PLATE FOR LITHOGRAPHIC PRINTING PLATE AND METHOD OF MANUFACTURING LITHOGRAPHIC PRINTING PLATE SUPPORT - An aluminum alloy plate for a lithographic printing plate capable of obtaining a lithographic printing plate having an excellent resistance to spotting, a method of manufacturing such aluminum alloy plate, a lithographic printing plate support obtained by using such aluminum alloy plate, and a presensitized plate and in particular an on-machine developable presensitized plate are provided. The aluminum alloy plate contains 0.08 to 0.45 wt % of iron and to 0.20 wt % of silicon, with the balance being inadvertent impurities and aluminum, and the content of aluminum-iron intermetallic compounds is not more than 0.05 wt %. | 10-22-2009 |
20100229938 | ALUMINUM ALLOY SUBSTRATE AND SOLAR CELL SUBSTRATE - An aluminum alloy substrate having excellent insulating performance and withstand voltage characteristics and high strength at elevated temperatures, and a method of efficiently producing a flexible thin-film solar cell by a roll-to-roll process using the aluminum alloy substrate are provided. The substrate has an oxide film of more than 1 μm to 30 μm thickness having insulating properties on a surface of an aluminum alloy containing 2.0 to 7.0 wt % of magnesium, the balance being aluminum and inevitable impurities. | 09-16-2010 |
20100276001 | METAL COMPOSITE SUBSTRATE AND METHOD OF PRODUCING THE SAME - A metal composite substrate includes a core made of a metal having higher strength than aluminum at elevated temperatures of at least 300° C. and an aluminum or aluminum alloy layer covering an entire surface of the core, and an anodized film is formed at a surface of the aluminum or aluminum alloy layer. The metal composite substrate having the anodized surface film can produce with high efficiency an insulating flexible support by a roll-to-roll process and has good flatness during the high-temperature heat treatment. | 11-04-2010 |
20120189959 | LITHOGRAPHIC PRINTING ORIGINAL PLATE - A presensitized plate having a long press life and excellent resistance to scum and corrosive micro-stains and capable of on-press development is provided. The presensitized plate includes a photosensitive layer containing (A) a sensitizing dye, (B) a polymerization initiator, (C) a polymerizable compound, and (D) a binder polymer; and a protective layer which are formed on a support in this order. The support is prepared from an aluminum alloy plate containing intermetallic compound particles with a circle equivalent diameter of 0.2 μm or more at a surface density of 35,000 pcs/mm | 07-26-2012 |
20120192742 | LITHOGRAPHIC PRINTING PLATE SUPPORT AND PRESENSITIZED PLATE - A lithographic printing plate support includes an aluminum plate and an anodized film formed at a surface of the aluminum plate and having micropores which extend in a depth direction of the anodized aluminum film from a surface of the anodized film opposite from the aluminum plate. Each of the micropores includes a large-diameter portion and a dendritic small-diameter portion. The lithographic printing plate support has excellent scratch resistance and is capable of obtaining a presensitized plate which exhibits excellent on-press developability and enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking ability after suspended printing. | 08-02-2012 |
20120298001 | SUPPORT FOR PLANOGRAPHIC PRINTING PLATE, METHOD FOR PRODUCING SUPPORT FOR PLANOGRAPHIC PRINTING PLATE, AND PLANOGRAPHIC PRINTING ORIGINAL PLATE - Provided is a lithographic printing plate support that has excellent scratch resistance and is capable of obtaining a presensitized plate which exhibits excellent on-press developability and enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking ability after suspended printing. The lithographic printing plate support includes an aluminum plate, and an aluminum anodized film formed thereon and having micropores which extend in a depth direction of the anodized film from a surface of the anodized film opposite from the aluminum plate. Each micropore has a large-diameter portion which extends to a depth of 5 to 60 nm (depth A) from the anodized film surface, and a small-diameter portion which communicates with the bottom of the large-diameter portion, further extends to a depth of 900 to 2,000 nm from the communication position and has a predetermined average diameter. | 11-29-2012 |
20140326151 | LITHOGRAPHIC PRINTING PLATE SUPPORT, LITHOGRAPHIC PRINTING PLATE SUPPORT MANUFACTURING METHOD AND LITHOGRAPHIC PRINTING PLATE PRECURSOR - The present invention provides a lithographic printing plate support, comprising an aluminum plate and an anodized film of aluminum formed on the aluminum plate and having micropores extending in the anodized film from a surface of the anodized film opposite from the aluminum plate in a depth direction, wherein each of the micropores has a large-diameter portion having a specific shape and a small-diameter portion having a specific shape and communicating with a bottom of the large-diameter portion; at least a part of an inside of the small-diameter portion is sealed with protrusions made of boehmite; and a ratio of an average height of protrusions made of boehmite inside the large-diameter portion to an average diameter of the large-diameter portion at the surface of the anodized film is up to a predetermined value. | 11-06-2014 |
20150024325 | LITHOGRAPHIC PRINTING ORIGINAL PLATE - A presensitized plate having a long press life and excellent resistance to scum and corrosive micro-stains and capable of on-press development is provided.
