  • Patent number: 11932767
    Abstract: To provide an active energy ray-curable ink composition that contains high rates of raw materials derived from biomass and can maintain basic characteristics, such as compatibility. Provided is an active energy ray-curable ink composition containing a pigment, a compound having ethylenically unsaturated bonds, and a rosin-modified alkyd resin, wherein the rosin-modified alkyd resin is a condensed polymer of an acid ingredient containing a resin acid, a fatty acid, and a polybasic acid with a polyhydric alcohol, and has a solubility parameter (sp) value of 9.0 to 11.0 (cal/cm3)1/2 as measured by turbidimetric titration and an acid value of 1 to 50 mg KOH/g.

  • Publication number: 20220145105
    Abstract: An object is to obtain an electron beam-curable printing ink composition that maintains such basic properties as curability, adhesion, scratch resistance, etc., without containing any traditional polymerization initiator. As a solution, an electron beam-curable printing ink composition is provided that contains dimethylpolysiloxane by 0.1 to 3.5% by mass relative to the total composition.
