[0103] Production Example 1 Synthesis of diallyl 1,2-cyclohexanedicarboxylate polymer

[0104] Diallyl 1,2-cyclohexanedicarboxylate is produced by esterifying cyclohexanedicarboxylic anhydride and allyl alcohol.

[0105] 2,400 g of diallyl 1,2-cyclohexanedicarboxylates were put in a 3 L separable flask, 60 g of benzoyl peroxide was added, and it heated and stirred at 80 degreeC. After making it react for 2.5 hours, it cooled to 30 degreeC. After cooling, methanol was added to the flask to precipitate the polymer. The obtained polymer was dried under reduced pressure at 40° C. for 16 hours (yield: 408 g, yield: 17%, Mw=32000, Mw / Mn=2.8). The obtained polymer was referred to as polymer 1.

[0107] (1) Preparation of varnish

[0108] 35 parts by weight of the resin (the above-mentioned polymer 1), 65 parts by weight of DTMPTA (SR-355NS: di(trimethylol)propane tetraacrylate manufactured by Sartomer Co., Ltd.), a polymerization inhibitor (IRGANOX1076: manufactured by BASF Japan Co., Ltd. 3-(3,5-di-tert-butyl-4-hydroxyphenyl)octadecyl propionate) was added at a ratio of 0.3 parts by weight, and it was thermally dissolved at 100° C. to prepare a light yellowish transparent varnish.

[0109] (2) Preparation of gel varnish

[0110] With respect to 100 parts by weight of the varnish prepared in (1), 0.6 parts by weight of a gelling agent (ALCH: aluminum diisopropoxide-ethyl acetoacetate (aluminum complex compound) manufactured by Kawaken Fine Chemical Company) was added (Example 1 ), a gelling agent (Orgatics ZC-150: zirconium tetraacetylacetonate (organic zirconium) manufactured by Matsumoto Fine Chemical Co., Ltd.) 1.0 parts by weight (Example 2), stirred at 110° C. f...

Abstract

An object of the present invention is to provide a photocurable resin composition capable of constituting a composition excellent in printing suitability. The present invention relates to a photocurable resin composition characterized by comprising: an allyl polymer (A) obtained by polymerizing an allyl compound represented by the following general formula (I); and, Gelling agent (B) [in general formula (I), R 1 and R 2 represent H or CH respectively 3 , X represents a saturated or partially unsaturated four- to eight-membered ring skeleton having no substituent, and is an a-valent group, and a represents 2 or 3. ].

Description

technical field [0001] The present invention relates to a photocurable resin composition containing an allyl polymer (A) and a gelling agent (B), and an ink and paint containing the resin composition. In more detail, it is related with the photocurable resin composition excellent in printing suitability. Background technique [0002] Conventionally, various resin compositions cured by light (for example, ultraviolet rays) have been used in inks, paints, adhesives, photoresists, and the like. For example, UV-curable printing inks are highly evaluated in terms of being able to cure in a short time due to their high curing speed, being environmentally friendly because they do not use solvents, and saving resources and energy, and their practical use is advancing. [0003] Such a resin composition contains diallyl phthalate derived from diallyl phthalate (diallyl phthalate, diallyl isophthalate, diallyl terephthalate). A resin composition of an allyl ester resin is used as a U...
