LIGHT-SHIELDING SLIDING FILM, LIGHT-SHIELDING SLIDING MEMBER, AND RESIN COMPOSITION FOR LIGHT-SHIELDING SLIDING FILM

摘要

Provided are a light-shielding sliding film, a light-shielding sliding member, and the like having excellent coating film strength and abrasion resistance. A light-shielding sliding film 21 containing at least: a urethane-based binder resin which is a cured material of a polyol and a polyisocyanate curing agent, the blending ratio of the polyol and the polyisocyanate curing agent being 1:1.21-1.40 in terms of the ratio of NCO groups of the polyisocyanate curing agent and OH groups of the polyol; carbon black; and a particulate wax is provided on one or more surfaces 11a, 11b of a substrate 11. Preferably, the light-shielding sliding film 21 essentially does not contain an inorganic filler having an average particle diameter D₅₀ of 3.0 µm or greater and/or resin beads having an average particle diameter D₅₀ of 3.0 µm or greater.
