Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an acrylic resin composition not only having excellent transparency but also having excellent characteristics such as rigidity, hardness and heat resistance, and to provide a method for producing the acrylic resin composition and a molded article comprising the acrylic resin composition. SOLUTION: The acrylic resin composition contains colloidal silica of 1-50 pts.wt., having ≤50 nm average particle diameter based on 100 pts.wt. of the acrylic resin, and exhibits ≥85% total light transmittance in a visual light region and ≤1.5% haze after melt formation. The method for producing the acrylic resin composition includes mixing and adding a colloidal silica surface-treated with a surface modifier having
