  • Positive working lithographic printing plate precursor and process for preparing lithographic printing plate
    Patent number: 9250524
    Abstract: The present invention relates to a positive working lithographic printing plate precursor, comprising: (1) a substrate; and (2) an imaging layer, formed on the substrate, comprising a water-insoluble and an alkaline aqueous solution-soluble or dispersible resin and a photo-thermal converting material, wherein the imaging layer comprises either polyurethane or polyurethane urea or both of the polyurethane and the polyurethane urea, the polyurethane and the polyurethane urea comprising a unit having a substituent having an acidic hydrogen atom and a unit having a polysiloxane moiety in a side or main chain. The present invention can provide a lithographic printing plate precursor which has high printing durability, good scratch resistance, and good developing properties, as well as enhanced ink receptivity.

  • Composition for a thermal lithographic printing plate and lithographic printing plate comprising the composition
    Publication number: 20040023155
    Abstract: Thermally imageable elements useful in lithographic printing are disclosed. The element has a layer of an imageable composition over a support. The imageable composition contains a supramolecular polymer that includes QHB-modified polymeric molecules having the structure A-L-B. A and B are each different QHB-modified portions selected from QHB-modified phenolic portions, QHB-modified acrylic portions, QHB-modified polyester portions, and QHB-modified polyurethane portions. L is a joining group. The elements are suitable for the preparation of lithographic printing plates.
