Synthetic example 1

[0138] (Synthesis example 1 (production of polyurethane prepolymer A))

[0139] 100 parts by weight of polytetramethylene ether glycol (manufactured by Mitsubishi Chemical Corporation, "PTMG-2000") and 0.01 part by weight of dibutyltin dilaurate were charged into a 500-mL separable flask as a polyol, Stir and mix at 100° C. for 30 minutes under vacuum (below 20 mmHg). Thereafter, the pressure was set to normal pressure, 26.5 parts by weight of PureMDI (manufactured by Nisso Shoji Co., Ltd.) was added as a diisocyanate, stirred at 80° C. for 3 hours, and reacted to obtain a polyurethane prepolymer A (weight average molecular weight: 2700).

Synthetic example 2

[0140] (Synthesis example 2 (production of polyurethane prepolymer B))

[0141] 100 parts by weight of polypropylene glycol (manufactured by Asahi Glass Co., Ltd., "EXCENOL 2020") and 0.01 part by weight of dibutyltin dilaurate as a polyhydric alcohol were added to a 500-mL separable flask, under vacuum (20mmHg or less), 100°C Stir for 30 minutes and mix. Thereafter, the pressure was set to normal pressure, 26.5 parts by weight of PureMDI (manufactured by Nisso Shoji Co., Ltd.) was added as a diisocyanate, stirred at 80° C. for 3 hours, and reacted to obtain a polyurethane prepolymer B (weight average molecular weight: 2900).

Synthetic example 3

[0142] (Synthesis example 3 (production of polyurethane prepolymer C))

[0143] In the reaction container containing the polyurethane prepolymer A obtained in the same manner as in Synthesis Example 1, 1.3 parts by weight of hydroxyethyl methacrylate and N-nitrosophenylhydroxylamine aluminum salt (Wako Junyaku Kogyo Co., Ltd., "Q-1301") 0.14 parts by weight, stirred and mixed at 80° C. for 1 hour under a nitrogen stream to obtain a polyurethane prepolymer C (weight average molecular weight) having isocyanate groups and methacryloyl groups at molecular terminals 3100).

Abstract

The purpose of the present invention is to provide a light / moisture-curable resin composition that exhibits excellent storage stability and adhesive properties. Another purpose of the present invention is to provide an adhesive for electronic components and an adhesive for display elements, the adhesives comprising the light / moisture-curable resin composition. The present invention is a light / moisture-curable resin composition that contains a radically polymerizable compound, a moisture-curable urethane resin, a photo-radical polymerization initiator, and a water removal agent.

Description

[0001] technology area [0002] The present invention relates to an optical moisture-curable resin composition excellent in storage stability and adhesiveness. Moreover, this invention relates to the adhesive agent for electronic components and the adhesive agent for display elements produced using this optical moisture-curable resin composition. Background technique [0003] In recent years, liquid crystal display elements, organic EL display elements, and the like have been widely used as display elements featuring thinness, light weight, low power consumption, and the like. In these display elements, photocurable resin compositions are generally used for sealing liquid crystals and light-emitting layers; bonding substrates, optical films, protective films, and various members; and the like. [0004] However, in today's era when various mobile devices with display elements such as mobile phones and portable game consoles are widely used, miniaturization of display elements ...
