Abstract

　光拡散層のバインダー樹脂として熱硬化型樹脂を用いた光拡散フィルムにおいて、熱硬化型樹脂のもつ印刷適性や断裁適性を損なうことなく、所望の輝度とクラリティを得ること、特に輝度の向上とクラリティの抑制を図る。 　熱硬化型樹脂を主成分とするバインダー樹脂と光拡散剤とを含む光拡散層を備えた光拡散フィルムであって、バインダー樹脂は、分子中に親水性基を含有しない液状またはペースト状フッ素系添加剤を含む。液状またはペースト状フッ素系添加剤は、好適には、分子中に少なくとも１個のフルオロアルキル基と、少なくとも1個のエーテル結合を有し、バインダー樹脂１００重量部に対し３重量部以上、１６重量部以下含有される。
