Abstract:
The present invention addresses the problem of providing a (meth)acrylic resin composition which makes it possible to reduce the contamination of a roll and prevent the occurrence of silver streaks, and which has excellent stability. The present invention also addresses the problem of providing: a molded article using the (meth)acrylic resin composition; and a method for producing the (meth)acrylic resin composition. Provided is a (meth)acrylic resin composition that contains a (meth)acrylic polymer having, in a main chain thereof, a ring structure that is at least one of a lactone ring structure and a glutaric anhydride structure, the (meth)acrylic resin composition being characterized in that the content of phosphorus atoms in the (meth)acrylic resin composition is 1.0 ppm to 50 ppm inclusive and the content of a compound represented by formula (I) in the (meth)acrylic resin composition is 95 ppm or less.
