摘要： An inkjet ink that excels in feathering in plain paper recording, and that is suitable for recording free from beading, color bleed, etc. on a medium with low or no ink absorptivity; and a method of recording with the use of the ink. There is provided an inkjet ink comprising at least a colorant, water and a polymer compound composed of a hydrophilic backbone chain having multiple side chains among which a crosslink bond can be made by irradiation with actinic energy rays, characterized in that the colorant is anionic while the side chains of the polymer compound are anionic or nonionic.

摘要： A method of plate making in which while utilizing the characteristics of convenience and high productivity attained by inkjet process, there are improved the plate life, resolving power and inking property having been problems of inkjet process plate making, and in which realizing high hardening sensitivity, plate making can be accomplished by a simple apparatus with the use of low-viscosity inkjet ink; and a lithographic printing plate obtained by the method.; There is provided a method of plate making through the sequential procedure of applying a plate making ink onto a printing plate material according to an inkjet recording technique, irradiating the ink with actinic energy rays, evaporating the ink solvent and drying to thereby attain image forming and thus obtain a printing plate, characterized in that the plate making ink contains at least water and an actinic energy ray hardening polymeric compound of 200 to 4000 polymerization degree amounting to 0.8 to 5.0 mass% based on the total mass of the ink. The polymeric compound in its main chain has multiple side chains such that therebetween, crosslink bonding can be effected by irradiation with actinic energy rays.
