Document Type and Number:
WIPO Patent Application WO/2022/244218
Kind Code:
A1
Abstract:
[Problem] To provide a layered product that can be mass-produced, and in which a layer having water repellency and/or oil repellency is less likely to be detached or drop off. [Solution] This layered product is obtained by forming, on a base film, a porous functional layer including a thermoplastic resin and a three-dimensional mesh structure in which fine particles having water repellency and/or oil repellency are firmly attached together. The layered product is characterized in that the porosity of the porous functional layer is 1-50 vol% in a region extending in the thickness direction thereof from the bottom surface thereof to a depth of 50% of the thickness thereof, and 50-99 vol% in a region extending in the thickness direction thereof from a depth of 50% of the thickness thereof to the top surface of the porous functional layer.
