Description

technical field

[0001] The invention relates to a radiation curable inkjet composition and an inkjet method. Background technique

[0002] The inkjet recording method is capable of recording high-definition images with a relatively simple device, and has achieved rapid development in various aspects. Among them, various studies have been conducted on the curability of coating films of inkjet compositions cured by irradiation with radiation, and the like. For example, in Patent Document 1, for the purpose of providing an ultraviolet curable inkjet ink composition having excellent curability in both a thin film cured film and a thick film cured film, an ultraviolet curable ink composition is disclosed. An inkjet composition comprising: a vinyl ether group-containing (meth)acrylate; a monofunctional (meth)acrylate having an aromatic ring skeleton; and a photopolymerizable initiator.
