Description
［比較例２］
温度計、撹拌装置、還流冷却管、滴下装置を備えた４ツ口フラスコに、ポリエチレングリコール（水酸基価＝１８７）１５質量部、メチルエチルケトンを１００質量部加え、４０℃で十分に攪拌溶解後、４０℃でトリレンジイソシアネート３０質量部を添加し、６０〜６５℃で４時間反応させた。次いで、ビスフェノールＡ型エポキシ樹脂〔エピクロン１０５０、ＤＩＣ（株）製、エポキシ当量４７７ｇ／当量〕８０質量部を加えて６０〜６５℃で１時間反応し、更にメタノール４質量部を加え、６０〜６５℃で４時間反応させることによって、エポキシ基を有するウレタン樹脂（ａ２−５）組成物を得た。前記ウレタン樹脂の重量平均分子量は１０，０００であった。
[Comparative Example 2]
15 parts by mass of polyethylene glycol (hydroxyl value = 187) and 100 parts by mass of methyl ethyl ketone were added to a four-necked flask equipped with a thermometer, a stirrer, a reflux condenser, and a dripping device. 30 parts by mass of tolylene diisocyanate was added at 60 ° C. and reacted at 60 to 65 ° C. for 4 hours. Next, 80 parts by mass of a bisphenol A type epoxy resin [Epiclon 1050, manufactured by DIC Corporation, epoxy equivalent 477 g / equivalent] was added and reacted at 60 to 65 ° C. for 1 hour, and further 4 parts by mass of methanol was added, and 60 to 65 ℃ Thus to be 4 hours gave the urethane resin (a2-5) composition having an epoxy group. The weight average molecular weight of the urethane resin was 10,000.
