A polymerizable composition comprising a syrup composition (α) and a polymerization initiator (β), wherein the syrup composition (α) contains a copolymer (C) and at least one (meth)acrylate selected from a di(meth)acrylate (A) represented by the general formula (1) and a mono(meth)acrylate (B), wherein the copolymer (C) is obtained by polymerization of a monomer mixture containing 1 to 60 wt % of the di(meth)acrylate (A) represented by the following general formula (1): CH2═CR1—COO—(X)—COCR1═CH2 (1) (wherein, (X) represents at least one residue selected from a polyalkylene glycol, a polyester diol and a polycarbonate diol having a number-average molecular weight of 500 or more, and R1 represents H or CH3) and 40 to 99 wt % of the mono(meth)acrylate (B); and an acrylic resin film 1 having flexibility and high transparency obtained by polymerizing and curing the polymerizable composition.
