    摘要： Provided is an ink jet recording method including recording an infrared absorbing image by applying a first ink, which contains an infrared absorber and a first curable compound, onto an impermeable substrate by an ink jet method, semi-curing the infrared absorbing image by irradiating the infrared absorbing image with active energy rays, recording a non-infrared absorbing image by applying a second ink, which has a content of the infrared absorber of lower than 0.1% by mass and contains a second curable compound, to a surface of the substrate with the infrared absorbing image by the ink jet method, and curing the semi-cured infrared absorbing image and the non-infrared absorbing image by irradiating these images with active energy rays.

    摘要： To provide a resin for ink compositions that is usable in the preparation of active energy ray-curable ink compositions and that can increase a proportion of biomass-derived ingredients.
    A polyester resin that is a condensation polymer of an acid ingredient including a fatty acid containing an epoxy group and a polybasic acid, and a polyhydric alcohol is employed, wherein the fatty acid has a peroxide value of 1 meq/kg or more in terms of triglyceride. Such a resin is prepared by a process for producing the polyester resin through heating a mixture containing an epoxidized oil or fat, a polybasic acid, and a polyhydric alcohol to subject to a transesterification reaction and a polycondensation reaction, wherein the epoxidized oil or fat has a peroxide value of 1 meq/kg or more.
