To provide an additive for light control films and a thermosensitive light control film that can control the transparency or non-transparency of a light control film according to the temperature.SOLUTION: An additive for light control films according to the present invention comprises a side chain crystallizable polymer that crystalizes at a temperature below a melting point thereof and that exhibits flowability at a temperature higher than or equal to the melting point. A thermosensitive light control film according to the present invention contains: the additive for light control films; and a base resin. The thermosensitive light control film is transparent at a temperature below the melting point and may be non-transparent at a temperature higher than or equal to the melting point.SELECTED DRAWING: None 【課題】調光フィルムの透明および非透明を温度で制御できる調光フィルム用添加剤および感温性調光フィルムを提供することである。【解決手段】本発明の調光フィルム用添加剤は、融点未満の温度で結晶化し、且つ、前記融点以上の温度で流動性を示す側鎖結晶性ポリマーからなる。本発明の感温性調光フィルムは、前記調光フィルム用添加剤と、ベース樹脂と、を含有する。感温性調光フィルムは、前記融点未満の温度で透明であり、前記融点以上の温度で非透明であってもよい。【選択図】なし
