An acrylic pressure-sensitive adhesive composition according to the present invention comprises: acrylic copolymer (A) formed by copolymerizing i) alkyl (meth) acrylic acid ester monomer wherein the carbon atom of alkyl group is 2 to 14, ii) monomer having a functional group capable of crosslinking, iii) methyl (meth)acrylate monomer, iv) vinyl acetate monomer, v) glycidyl (meth)acrylate, and vi) crosslinking agent having 5 to 15 of alkyleneoxide groups and at least two acrylate group or vinyl group; and flame retardant (B). The acrylic pressure-sensitive adhesive composition improves the adhesive property and the dispersion of the flame retardant by controlling the crosslinking structure of the acrylic copolymer, such that a surface finishing material comprising the same can have the excellent adhesion and fireproof.
