To provide a film capable of improving adhesion to an ultraviolet curable ink to be applied, and a method for manufacturing the same.SOLUTION: A film 1 to which an ultraviolet curable ink is applied includes a base material 10 and an ink receiving layer 11 to which the ultraviolet curable ink is applied and which is harder than the base material, and the ink receiving layer is constituted of a material including a polymer including an acrylic structure and a carbon-carbon unsaturated bond. When an indentation depth when applying a load by a triangular pyramid indenter having an inter-ridge angle of 115° until the load is 10 mN to indent the ink receiving layer and hold the load for one second is A and an indentation depth after removing the load is B, B/A is 0.4 or more and 0.65 or less.SELECTED DRAWING: Figure 1 【課題】付与される紫外線硬化型インクとの密着性を向上したフィルムおよびフィルムの製造方法を提供する。【解決手段】紫外線硬化性インクが付与されるフィルム１であって、基材１０と、紫外線硬化性インクが付与され、基材よりも硬質なインク受容層１１と、を備え、インク受容層は、アクリル構造と、炭素−炭素不飽和結合とを含むポリマーを含む材料で構成されており、稜間角が１１５°の三角錐の圧子で、荷重が１０ｍＮになるまで負荷を与えて前記インク受容層を押し込み、１秒間保持した際の押し込み深さをＡとし、除荷した後の押し込み深さをＢとしたとき、Ｂ／Ａが０．４以上０．６５以下であることを特徴とするフィルム。【選択図】図１
