Abstract

The present invention provides an active light curing type composition and an ink composition containing the active light curing type composition. The active light-curable composition is characterizedby containing (A) a nonionic surfactant having a HLB of less than 5 represented by a specific formula, (B) a photocurable monomer and / or oligomer, and (C) a photopolymerization initiator. The contentof the component (A) is from 0.01 to 5.0% by mass. The active light-curable composition of the present invention can exhibit wettability to a material lacking ink absorbability, excellent scratch resistance at the time of forming a coating film, and antifouling property to an oil-based marker or the like. In the case of an ink composition for a transparent ink, high transparency can be imparted.

Description

technical field [0001] The present invention relates to an active light-curable composition containing a nonionic surfactant, a photocurable monomer, and a photopolymerization initiator, and an ink composition containing the active light-curable composition. Background technique [0002] Conventionally, active ray-curable compositions that are cured by active energy rays such as ultraviolet rays and electron beams have been used in coatings, coating agents, adhesives, printing inks, and inks for plastics, paper, glass, woodworking, and inorganic materials. It has been put into practical use in various applications such as receiving layers, printed circuit boards, and electrical insulation. In particular, active ray-curable inks are attracting attention because they are quick-drying and can record on materials that lack ink absorption. [0003] For the nonionic surfactant used in such an active ray-curable composition, solubility in the photocurable monomer is required, as w...
