Description
メチルエチルケトン3,281質量部及びオクチル酸第一錫0.1質量部の存在下、ポリカーボネートポリオール(日本ポリウレタン株式会社製「ニッポラン980R」、数平均分子量;2,000)1,000質量部と、2,2−ジメチロールプロピオン酸17質量部と、エチレングリコール47質量部と、ジフェニルメタンジイソシアネート344質量部とを溶液粘度が20,000mPa・sに達するまで70℃で反応させた後、メタノール3質量部を加えて反応を停止させてウレタン樹脂(A−1)のメチルエチルケトン溶液を得た。このウレタン樹脂溶液にポリオキシエチレンジスチレン化フェニルエーテル(Hydrophile−Lipophile Balance(以下、「HLB」と略記する);14)70質量部と、トリエチルアミン13質量部を混合させた後に、イオン交換水800質量部を加えて転相乳化させることで前記ウレタン樹脂(A−1)が水に分散した乳化液を得た。
次いで、前記乳化液からメチルエチルケトンを留去することによって、不揮発分40質量%のウレタン樹脂組成物(X−1)を得た。なお、前記ウレタン樹脂(A−1)中の芳香環の含有量は、1.93mol/kgであった。
