20080305435 | METHOD OF MAKING LITHOGRAPHIC PRINTING PLATE SUBSTRATE AND IMAGEABLE ELEMENTS - Aluminum-containing substrates having an anodic oxide layer are coated with a interlayer by carefully controlling the concentration of phosphonic acid groups in an interlayer polymer and aluminum (+3) concentration in a post-treatment solution. These substrates have improved hydrophilicity, lithographic printing ink repellency, and overall improved printability when used as part of lithographic printing plates. | 12-11-2008 |
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 |
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 |
20140041541 | POSITIVE WORKING LITHOGRAPHIC PRINTING PLATE PRECURSOR AND A METHOD FOR MAKING A PRINTING PLATE - The present invention provides a CTP positive lithographic printing original plate which has satisfactory image contrast even after baking. | 02-13-2014 |
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 |
