▎ 摘　　要

NOVELTY - Binder resin comprises methyl methacrylate, 3-7C alkyl methacrylate, at least one monomer comprising hydroxyalkyl 2-4C methacrylate or condensed monomer of saturated diacid compound and hydroxy 3-4C alkyl methacrylate, and cycloalkyl methacrylate, styrene and/or benzyl methacrylate are polymerized. USE - The binder resin is useful in coating composition for forming electromagnetic wave shielding film (all claimed). ADVANTAGE - The binder has excellent: surface hardness, weather resistance, dispersibility, spray discharge property, transparency, low yellowing degree, oxidative stability, electrical conductivity, ejection properties, easy synthesis, handling and coating properties; and adhesion to electromagnetic compatibility substrate; and surface properties with contact angle to ethylene glycol of less than or equal to 40. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) coating composition comprising binder resin, electromagnetic shielding compounds and diluents; and (2) electromagnetic wave shielding film formed of the electromagnetic wave coating composition.
