The present invention provides a flame retardant acrylic-based copolymer. The flame retardant acrylic-based copolymer comprises a derivation unit obtained from a monomer miture including: (A) a (metha)acrylic-based monomer; (B) at least one vinyl-based monomer selected from a group consisting of an aromatic vinyl-based monomer and an unsaturated nitrile-based monomer; and (C) a recurring unit derived from a monomer having a phosphorus-based (metha)acrylic-based monomer. The flame retardant acrylic-based copolymer has a high refractive index and good flame retardant properties and scratch resistance.
