PURPOSE: A polymethyl methacrylate resin composition is provided to ensure excellent weather resistance, surface hardness, colorability and glossiness, and to reduce a die line and micro scratch due to excellent elasticity. CONSTITUTION: A resin composition for capstock includes, based on 100 parts by weight of a polymethyl methacrylate-based resin, 100~200 parts by weight of two kinds or more of an impact reinforcing agent with different particle diameter, and 0.4~5 parts by weight of a UV stabilizer. The impact reinforcing agent with different particle diameter includes impact reinforcing agents having an average particle diameter of 0.20~0.25 micron and average particle diameter of 0.15~0.19 micron.
