20080280228 | Photosensitive Planographic Printing Plate - A photosensitive planographic printing plate comprising a substrate and a photosensitive layer including a photopolymerizable compound, wherein the photosensitive layer and the substrate are provided between them with an undercoat layer including a (co)polymer having structural units having ethylenically unsaturated groups bonded with silicon atoms and phosphonic acid groups. | 11-13-2008 |
20090208869 | LITHOGRAPHIC-PRINTING PLATE PRECURSOR AND IMAGE FORMING METHOD USING THE SAME - To provide an infrared-sensitive or heat-sensitive lithographic printing plate precursor which has high printing durability and wide development latitude, and also has good developing properties capable of preventing the formation of deposits during the development. In an infrared-sensitive or heat-sensitive lithographic printing plate precursor, comprising a substrate, a first image recording layer formed on the substrate, and a second image recording layer formed on the first image recording layer, the first image recording layer contains a resin which is soluble or dispersible in an aqueous alkali solution, and the second image recording layer contains a polyurethane which has a substituent having an acidic hydrogen atom. | 08-20-2009 |
20100236436 | POSITIVE LITHOGRAPHIC PRINTING PLATE PRECURSOR AND METHOD FOR PRODUCING THE SAME - An object of the present invention is to provide a CTP positive working lithographic printing original plate capable of developing using a negative developing solution. | 09-23-2010 |
20110011291 | METHOD FOR MAKING LITHOGRAPHIC PRINTING ORIGINAL PLATE - An object of the present invention is to provide a method for plate-making of a lithographic printing original plate having excellent restart toning recovery properties, and particularly an infrared-sensitive positive working lithographic printing original plate. | 01-20-2011 |
20110053085 | LITHOGRAPHIC PRINTING PLATE PRECURSORS AND STACKS - Lithographic printing plate precursors have been designed so that they can be stored, shipped, and used in stacks without interleaf paper between individual precursors. This is achieved by incorporating polymeric particles having an average diameter of from about 3 to about 20 μm into the outermost precursor layer such as an imageable layer or topcoat. The polymeric particles comprise a core of a crosslinked polymer and have grafted hydrophilic polymeric surface groups that are grafted onto the particle surfaces by polymerizing hydrophilic monomers in the presence of the crosslinked polymeric particles. The lithographic printing plates can be either negative- or positive-working elements. | 03-03-2011 |
20120070779 | LITHOGRAPHIC PRINTING PLATE PRECURSOR - The present invention provides a lithographic printing plate precursor which exhibits satisfactory ink cleanup and restart toning characteristics during printing. | 03-22-2012 |
20140116277 | POSITIVE LITHOGRAPHIC PRINTING PLATE PRECURSOR AND METHOD FOR PRODUCING THE SAME - A CTP positive working lithographic printing original plate (precursor) is capable of being imaged and then developed using a negative developing solution. This positive working lithographic printing original plate has (1) a substrate thereon (2) a lower layer containing a water-insoluble and alkali-soluble resin and a photothermal conversion material, and (3) an uppermost layer containing a water-insoluble and alkali-soluble resin. In addition, the lower layer contains (a) a polymer having a perfluoroalkyl group and/or (b) a polymer having a siloxane group in a total amount of from 3 to 10% by mass. | 05-01-2014 |
20140255848 | LITHOGRAPHIC PRINTING PLATE PRECURSOR AND A METHOD FOR MAKING A PRINTING PLATE - An object of the present invention is to provide a lithographic printing plate precursor which exhibits satisfactory developability using a developing solution having the pH of 12 or lower and has long print run length and satisfactory scratch resistance, and also exhibits improved ink receptivity. | 09-11-2014 |
