    摘要: A method for making a negative-working heat-sensitive lithographic printing plate precursor includes the steps pf: (i) providing a support having a hydrophilic surface or which is provided with a hydrophilic layer; and (ii) applying on the support a coating which includes a product DQ, wherein DQ is obtained by: the step of coating a solution or dispersion including a nucleophilic compound Q and a dye D selected from the list consisting of di- or tri-arylmethane dyes, cyanine dyes, styryl dyes, and merostyryl dyes; or by D and Q interact to form interaction product DQ, having a white light optical density which is lower that the white light optical density of dye D; and the interaction product DQ is capable of at least partially releasing a dye directly after exposure to infrared light or heat, therby forming a visible image in the coating.
