▎ 摘　　要

NOVELTY - Composition comprises carbon-based particles, thermosetting binder resins, dispersants, polymer beads and solvents. The carbon-based particles are reduced graphene oxide particles, and/or graphene nano plate. The polymer beads are butyl methyl acrylate, polymethyl methacrylate or polymethylsilsesquioxane. USE - The composition is useful for preparing light-shielding film of smartphone camera module as spacer, washer and coating solution. ADVANTAGE - The light-shielding film: has low reflectance and improved blackness, glossiness, reflectance, and electrical characteristics; and suppress a flare phenomenon caused by internal light. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for light-shielding film made by applying the composition on film having a blackness (Lx ) of ≤ 20 and reflectance of ≤ 4.0.
