The waterproof membrane includes a resin sheet layer, a non-asphalt-based macromolecular self-adhesive layer and an interface bonding layer which are sequentially disposed, where the waterproof membrane has a light transmittance of ?45%. The present disclosure provides a visual waterproof membrane, that is, light may penetrate through the membrane to make gaskets visual, and when the membrane has a light transmittance of ?45%, it has good visibility for gaskets with warm colors such as orange and red.

An optical film has a base material and a hardcoat layer, in which a pencil hardness is 2H or higher, the number of times of folding endurance measured by an MIT tester is 1000 or more, an incident ray is made incident on the optical film from 60 with respect to a normal direction of the optical film, an angle width within which 10% of outgoing ray peak intensity is obtained is 6 or less, and an intensity of outgoing ray at 50 from the normal direction is 1% or less of the outgoing ray peak intensity. A method for manufacturing an optical film has a step of applying a hardcoat layer forming composition to a base material to provide a coating film, and a step of curing the coating film while bringing the coating film into contact with one smooth metal roll.

The present invention discloses methods for producing a covalently attached antioxidant coating using a multi-step coating process consisting of (1) exposing the substrate surface to plasma polymerization to produce a surface containing functional groups; (2) contacting the surface containing functional groups with crosslinking agents to produce a reactive surface; (3) contacting the reactive surface with a solution of one or more antioxidant compounds or a solution of one or more antioxidant-containing polymers. Alternatively, the third step is replaced by (3) contacting the reactive surface with a solution of one or more polymers to produce a polymer coated surface and (4) covalently attaching one or more antioxidant compounds to the polymer coated surface.
