preparation Embodiment 1

[0059] Preparation Example 1: Preparation of Acrylic Resin (PA-1)

[0060] 20 parts by weight of methyl methacrylate, 10 parts by weight of butyl methacrylate, 20 parts by weight of dicyclopentyl methacrylate, 30 parts by weight of isobornyl methacrylate and 15 parts by weight of benzene Ethylene was added as a polymerizable monomer into a flask equipped with a mechanical stirrer, thermometer, and cooling jacket. After stirring at room temperature (25° C.) for 30 minutes, 3 parts by weight of a thermal polymerization initiator (V-65, Wako) and 2 parts by weight of dodecyl mercaptan as a polymerization regulator were added to the monomer mixture. The internal temperature of the resulting solution was raised to 70°C. The solution polymerized for 4 hours. The reactor was cooled to 40° C. to quench the reaction, and an acrylic resin (PA-1) having a solid content of 100% and a weight average molecular weight of 25,000 was obtained.

[0061] Preparation Example 2: Preparation of Acrylic Resin (PA-2)

[0062] Acrylic acid was prepared in the same manner as in Preparation Example 1, except that the amount of styrene as a polymerizable monomer and the amount of dodecylmercaptan as a polymerization regulator were changed to 10 parts by weight and 7 parts by weight, respectively. Resin (PA-2). An acrylic resin having a solid content of 100% and a weight average molecular weight of 5,000 was obtained.

preparation Embodiment 3

[0063] Preparation Example 3: Preparation of Urethane Acrylate Resin (PUA-1)

[0064]Under nitrogen flow, 70 parts by weight of polypropylene glycol (PPG2700, Aldrich) was added into a flask equipped with a mechanical stirrer, a thermometer and a cooling jacket, heated to 40° C., and stirred. After adding 0.06 parts by weight of dibutyltin dilaurate, the temperature of the reactor was raised to 65°C. To the resulting solution was slowly added 20 parts by weight of isophorone diisocyanate. The reaction was continued at 65°C. During the reaction, the disappearance of the isocyanate group was monitored using an infrared spectrophotometer. When the disappearance of the isocyanate groups ceased, 10 parts by weight of 2-hydroxyethyl acrylate were slowly added to the reaction mixture. After using an infrared spectrophotometer to confirm that the isocyanate group completely disappeared, the reaction temperature was reduced to 40° C. to quench the reaction, and the obtained solid ...

Description

technical field [0001] The present invention relates to a radiation curable resin composition. Background technique [0002] Currently, most touch panels are based on direct bonding mounted on displays such as LCD, OLED and LED. Depending on the driving method of the touch panel, bonding is also performed between optical elements, such as between a decorative sheet and a touch panel, between a protective sheet and a touch panel, and between a transparent substrate forming a transparent electrode and a transparent sheet. Materials used to bond such elements need to have improved visibility and good durability against common factors such as water immersion, vibration and shock. Durability is especially important in displays for aircraft and marine applications. In technical applications in which adhesive materials are applied, adhesion is a basic requirement. Another requirement of the bonding material is high light transmission. Refractive index mismatches between the dis...
