Summary:To provide a laminate excellent in anti-fogging properties and tackiness, and suppressed wrinkle.SOLUTION: There is provided a laminate having a substrate and a surface layer arranged on at least one surface of the substrate, the surface layer contains a thermoplastic component and an anti-fogging component with HLB value of 12 to 19, and satisfying following requirement (1) to (4). (1) A surface resistance value of the surface layer is 1.0×10Ω to 1.0×10Ω. (2) An average of thickness is in a range of 0.5 μm to 2.0 μm. (3) Tackiness at 25°C is 20 N/cmor less. (4) A content of the anti-fogging component is 10.0 mg/mto 100 mg/m.SELECTED DRAWING: None 【課題】防曇性及びタック性に優れ、かつシワが抑制された積層体を提供する。【解決手段】基材と、前記基材の少なくとも一方の面に配置された表面層と、を備える積層体であって、前記表面層は、熱可塑性成分と、HLB値が12〜19の防曇成分と、を含み、かつ以下の要件(1)〜(4)のすべてを満たす、積層体。(1)前記表面層の表面抵抗値が1.0×108Ω〜1.0×1013Ωである。(2)厚さの平均値が0.5μm〜2.0μmの範囲内である。(3)25℃におけるタックが20N/cm2以下である。(4)前記防曇成分の含有量が10.0mg/m2〜100mg/m2である。【選択図】なし
