- the resulting reaction solution was treated with a thin-film distillation apparatus (vacuum level: 0.5 mmHg, temperature: 150 ° C) to remove unreacted hydrogenated xylylene diisocyanate, and then cooled to a non-volatile content of 80% by weight. Diluted with ethyl acetate. To this, 2-hydroxyethyl acrylate was added in an amount such that the remaining isocyanate groups and acrylate groups were equivalent, and monomethyl ether hydroquinone in an amount of 0.1% by weight was added to the total amount. Added.
- a four-necked flask equipped with a stirrer, thermometer, nitrogen gas inlet tube and Dimroth condenser tube was charged with 200 g of hydrogenated methylenebisphenol-diisocyanate and 2 g of monomethyl ether hydroquinone, and the reaction temperature was 70 under a nitrogen gas atmosphere. While controlling the temperature below ° C, 176.8 g of 2_hydroxystilyl acrylate was added dropwise. After the total amount was dropped, 0.1 g of dibutyltin laurate was further added, and the same temperature was maintained until the isocyanate group completely disappeared at a reaction temperature of 70 ° C. After cooling, dilute with ethyl acetate so that the non-volatile content becomes 80% by weight.
- Urethane acrylate was obtained.
- 37.5 g of this urethane acrylate (30 g of urethane acrylate) was mixed with 70 g of dipentaerythritol hexaatalylate and 3 parts by weight of Irgacure 184 (a photopolymerization initiator manufactured by Chino Specialty Chemicals).

The reaction was continued until the isocyanate content became 5.8% by weight while controlling the following. Subsequently, an additional 105 g of 2-hydroxyethyl talylate, monomethyl ether hydroquinone lg, and 0.2 g of dibutyltin laurate were added, and the temperature was maintained at 70 ° C. until the isocyanate group completely disappeared.
- nonvolatile content is diluted with acetic acid Echiru so that 80 weight 0/0 after cooling, to obtain a urethane Atari rate (U) of the present invention.
- U urethane Atari rate
- the photocurable coating material of Comparative Example 7 was obtained.
- the prepared photo-curing paint is applied to a predetermined substrate with an applicator and dried to a film thickness of 10 m, dried at 60 ° C for 1 minute, and then irradiated with an ultraviolet irradiation device with 3 lOOwZcm high-pressure mercury lamps. Ultraviolet rays were irradiated at an irradiation distance of 10 cm and a line speed of lOmZmin. The test piece thus obtained was used for the subsequent tests.
- PC polycarbonate
- PC polycarbonate
