摘要： PROBLEM TO BE SOLVED: To provide a method for preparing a negative-working lithographic printing plate exhibiting an improved clean-out and having shelf life stability with improved clean-out ability. SOLUTION: The method for preparing the negative-working lithographic printing plate comprises the steps of (1) providing a lithographic printing plate precursor comprising on a polished and anodized aluminum support, having a hydrophilic surface, a coating comprising (i) polymer particles which are core-shell particles having a hydrophobic heat-softenable core and a hydrophilic shell and (ii) an infrared light absorbing agent, (2) exposing the coating to heat, thereby inducing coalescence of the polymer particles at exposed areas of the coating, and (iii) developing the precursor by applying a gum solution to the coating, thereby removing non-exposed areas of the coating from the support. According to the above method the printing plates exhibit after ageing an improved clean-out and a reduced background stain, resulting in toning-free printing. COPYRIGHT: (C)2006,JPO&NCIPI
