Abstract: A method for making a negative-working heat-sensitive lithographic printing plate precursor is provided which comprises the steps of (i) providing a support having a hydrophilic surface or which is provided with a hydrophilic layer, and (ii) applying on said support a coating which comprises a product DQ, wherein DQ is obtained by - the step of coating a solution or dispersion comprising 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 - the step of coating a solution or dispersion comprising said compound Q and coating another solution or dispersion comprising said dye D; wherein D and Q interact to form interaction product DQ, having a white light optical density which is lower than the white light optical density of dye D, and wherein said interaction product DQ is capable of at least partially releasing a dye directly after exposure to infrared light or heat, thereby forming a visible image in said coating.

Abstract: An inkjet printing method includes the steps of: a) jetting on a substrate one or more aqueous UV curable inkjet inks including at least one photoinitiator and capsules composed of a cross-linked polymeric shell surrounding a core, with the core containing UV curable compounds; and b) applying UV radiation to the one or more aqueous UV curable inkjet inks jetted on the substrate.

Abstract: A pigment dispersion comprising a colour pigment represented by formula (I) wherein, R1 to R10 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, - CF3 , -COOH, -COOCH3; -SO2NH-C6H5, -CONH-C6H5, -CONH-C6H5-CONH2 and -CONH2; and a polymeric dispersant having via a linking group covalently linked to its polymeric backbone at least one pending chromophore group which has a molecular weight smaller than 95% of the molecular weight of said colour pigment. The pigment dispersion can be advantageously used in inkjet inks.
