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 compounding ratio described in Table 1 and Table 2, the active energy ray curable ink which can be used for inkjet printing was manufactured. Specifically, MIRAMER M3130 (ethylene oxide (EO)-modified trimethylolpropane triacrylate manufactured by MIWON Corporation), MIRAMER M240 (ethylene oxide (EO)-modified bisphenol 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 Co., Ltd. N-vinyl-2-caprolactam), LIGHT ACRYLATE POA (phenoxyethyl acrylate manufactured by Kyoeisha Chemical Co., Ltd.), tetrahydrofurfuryl acrylate composition containing a trace amount of tetrahydrofurfuryl alcohol, KF-54 (Shin-Etsu Chemical Co., Ltd. Co., Ltd. polysiloxane), stirred and mixed, then added Irgacure 819 (bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide manufactured by BASF Corporation), Irgacure.TPO (man...

Embodiment 7

[0178] According to the compounding ratio recorded in Example 7 of Table 3, MIRAMER M3130 (ethylene oxide (EO) modified trimethylolpropane triacrylate manufactured by MIWON Corporation), MIRAMER M240 (ethylene oxide (EO) modified by MIWON Corporation, alkane (EO) modified bisphenol A diacrylate), MEDOL-10 (manufactured by Osaka Organic Chemical Industry Co., Ltd., acrylic acid (2-methyl-2-ethyl-1,3-dioxolan-4-yl ) methyl ester), IBXA (isobornyl acrylate manufactured by Osaka Organic Chemical Industry Co., Ltd.), V-CAP (N-vinyl-2-caprolactam manufactured by ISP Corporation), LIGHT ACRYLATE POA (acrylic benzene manufactured by Kyoeisha Chemical Co., Ltd.) Oxyethyl ester), KF-54 (polysiloxane manufactured by Shin-Etsu Chemical Co., Ltd.), and stirred to mix, then add Irgacure 819 (bis(2,4,6-trimethylbenzoyl) manufactured by BASF -Phenylphosphine oxide), Irgacure.TPO (2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide manufactured by BASF Corporation), Kayacure DETX-S (diethylthiophe...

Embodiment 8

[0181] The amount of MEDOL-10 (manufactured by Osaka Organic Chemical Industry Co., Ltd., (2-methyl-2-ethyl-1,3-dioxolan-4-yl) methyl acrylate) was changed from 20 parts by mass to 27 parts by mass, the amount of POA (phenoxyethyl acrylate produced by Kyoeisha Chemical Co., Ltd.) was changed from 16.3 parts by mass to 9.3 parts by mass, except that the active energy was obtained by the same method as in Example 7 Radiation curable ink (C8).

Abstract

The problem to be solved by the present invention is to provide an actinic-ray-curable ink which, even when containing none of tetrahydrofurfuryl (meth)acrylate, tetrahydrofurfuryl alcohol, and the like or containing such a compound only in a small amount, has excellent adhesiveness to various substrates including plastic substrates. The problem was solved with an actinic-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 in the production of various printed matter. Background technique [0002] Active energy ray-curable inks are superior in curability and drying properties compared to other inks, and thus are used for printing on various recording media represented by, for example, 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 has been worried about the impact on the human body such as skin irritation and reproductive ability. Tetrahydrofurfuryl acrylate in...
