LAMINATED FILM

PROBLEM TO BE SOLVED: To provide a laminated film with less coloration while showing high heat-shielding performance.SOLUTION: A laminated film has: a unit A which is formed by alternately laminating a D layer which has thermoplastic resin D as a main component and an E layer which has thermoplastic resin E different from the thermoplastic resin D as a main component; a unit B which is formed by alternately laminating an F layer which has thermoplastic resin F as a main component and a G layer which has thermoplastic resin G different from the thermoplastic resin F as a main component; and a C layer containing heat-ray absorbing particles. The unit A is in one surface layer, and the unit B is in another surface layer, in which an average reflectance of light having a wavelength of 900 to 1200nm which is measured from a front surface side where the unit A is in the surface layer is 30% or more, an average reflectance of light having a wavelength of 700 to 800nm is less than 20%, and an average reflectance of light having a wavelength of 700 to 800nm which is measured from a front surface side where the unit B is in the surface layer is 20% or more and 80% or less.SELECTED DRAWING: None 【課題】 高い遮熱性能を示しつつも着色の少ない積層フィルムを提供する。【解決手段】熱可塑性樹脂Ｄを主成分とするＤ層と、熱可塑性樹脂Ｄとは異なる熱可塑性樹脂Ｅを主成分とするＥ層を交互に積層してなるユニットＡと、熱可塑性樹脂Ｆを主成分とするＦ層と、熱可塑性樹脂Ｆとは異なる熱可塑性樹脂Ｇを主成分とするＧ層を交互に積層してなるユニットＢと、熱線吸収粒子を含有するＣ層を有し、前記ユニットＡが一方の表層にあり、前記ユニットＢがもう一方の表層にある積層フィルムであって、前記ユニットＡが表層にある表面側から測定した波長９００〜１２００ｎｍの光の平均反射率が３０％以上、波長７００〜８００ｎｍの光の平均反射率が２０％未満であって、かつ、前記ユニットＢが表層にある表面側から測定した波長７００〜８００ｎｍの光の平均反射率が２０％以上８０％以下である、積層フィルム。【選択図】なし
