    摘要: Provided is a pressure-sensitive adhesive film suitable for an application involving cutting with a short-wavelength laser having a center wavelength of 1.0 μm to 1.1 μm. A pressure-sensitive adhesive film 1 according to the present invention comprises a resin film 10 as a substrate, and a pressure-sensitive adhesive layer 20 provided at least on a first face of resin film 10. Substrate 10 has a laser beam absorbance of 20% or higher in a wavelength range of 1000 nm to 1100 nm, and comprises a laser beam-absorbing layer 42 comprising a laser beam-absorbing agent 402 that increases the laser beam absorbance. As laser beam-absorbing agent 402, at least one species selected from a metal powder and a metallic compound powder can be preferably used.

    摘要: There are provided an optical surface protection film capable of permitting even a visual inspection of a coated body having a fine roughness, such as a prism sheet, to be performed under the condition that the protection film is attached to the coated body and excelling in adhesion reliability without an optical adverse effect on the coated body, and an optical film with the surface protection film. The optical surface protection film (1) has a base material layer (10) and an adhesive layer (12) stacked on one surface of the base material layer. The surface of the base material layer (10) on the side of the adhesive layer (12) has an arithmetic surface average roughness (Ra2) of 0.65 μm or less. The other surface of the base material layer (10) has an arithmetic surface average roughness (Ra1) of 0.6 μm or more.
