发明名称 Processing Liquid for Lithographic Printing Plate Development and Method of Producing Lithographic Printing Plates
摘要 A processing liquid for lithographic printing plate development is provided. This processing liquid is safe and exhibits an excellent developability and processing capacity. A method of producing a lithographic printing plate using this processing liquid is also provided. This method can be employed for single-liquid processing and avoids a reduction in printing durability when the printing plate is stored after development until the time comes for printing; this method also provides nonimage areas that are resistant to scumming when printing is carried out. The processing liquid for lithographic printing plate development contains (1) a water-soluble amine compound and an ion of this amine compound and (2) at least one selection from a water-soluble polymer compound and a surfactant. The method of producing a lithographic printing plate comprises: after imagewise photoexposing a negative-working lithographic printing plate precursor that has an image recording layer containing the (i), (ii), (iii), and (iv) described below on a hydrophilic support, developing the negative-working lithographic printing plate precursor with the previously described processing liquid. (i) sensitizing dye (ii) a photopolymerization initiator (iii) an addition-polymerizable compound that has an ethylenically unsaturated double bond (iv) binder polymer
