Problems solved by technology

[0005] On the other hand, inks that do not contain tetrahydrofurfuryl acrylate sometimes cause a decrease in adhesion to plastic substrates
[0006] Therefore, from the perspective of the industry, the actual situation is that although it is required to develop an active compound that does not contain the aforementioned tetrahydrofurfuryl (meth)acrylate, tetrahydrofurfuryl alcohol, etc., or has a reduced content, and has excellent adhesion to plastic substrates, Energy ray curable inks, but not yet discovered

Embodiment 1～6 and comparative example 1～4

[0136] According to the mixing ratios described in Tables 1 and 2, active energy ray-curable inks that can be used for inkjet printing were produced. Specifically, MIRAMER M3130 (ethylene oxide (EO)-modified trimethylolpropane triacrylate manufactured by MIWON Corporation) and MIRAMER M240 (ethylene oxide (EO)-modified bisphenol manufactured by MIWON Corporation) were added to the container. A diacrylate), V-190 (Ethoxyethoxyethyl acrylate, manufactured by Osaka Organic Chemical Industry Co., Ltd.), IBXA (Isobornyl Acrylate, manufactured by Osaka Organic Chemical Industry Co., Ltd.), V-CAP (manufactured by ISP Corporation) N-vinyl-2-caprolactam), LIGHT ACRYLATE POA (phenoxyethyl acrylate manufactured by Kyeisha Chemical Co., Ltd.), tetrahydrofurfuryl acrylate composition containing a trace amount of tetrahydrofurfuryl alcohol, KF-54 (Shin-Etsu Chemical Industry Co., Ltd. Polysiloxane manufactured by Co., Ltd.), stirred and mixed, and then added Irgacure 819 (bis(2,4,6-trimethy...

Abstract

The problem to be solved by the present invention is to provide an active energy ray-curable ink that is compatible with plastic substrates represented by plastic substrates even when tetrahydrofurfuryl (meth)acrylate, tetrahydrofurfuryl alcohol, etc. are not contained or their contents are small. The adhesion performance of various substrates is also excellent. The present invention solves the above-mentioned problems by utilizing an active energy ray-curable ink characterized by containing a polymerizable compound (A) having a specific structure.

Description

technical field [0001] The present invention relates to an active energy ray-curable ink that can be used for the production of various printed matters. Background technique [0002] Compared with other inks, active energy ray-curable inks are excellent in curability and drying properties, and are therefore used for printing on various recording media such as plastic films. [0003] As the active energy ray-curable ink, for example, an ink composition containing a colorant, a radical polymerization initiator of a specific structure, and a radical polymerizable compound such as tetrahydrofurfuryl acrylate is known (for example, refer to Patent Document 1). [0004] However, tetrahydrofurfuryl acrylate may contain a small amount of tetrahydrofurfuryl alcohol in the form of impurities, decomposition products, etc. in recent years, which is concerned about the effects on the human body such as skin irritation and reproductive performance. The tendency of tetrahydrofurfuryl acry...
