An acrylic resin composition comprising the following acrylic resins (1) and (2): acrylic resin (1): an acrylic resin containing a structural unit derived from a monomer (a) (structural unit (a)), a structural unit derived from a monomer (b) (structural unit (b)) and a structural unit derived from a monomer (c) (structural unit (c)) and containing the structural unit (c) in an amount of 0.05 to 5 parts by weight based on 100 parts by weight of the acrylic resin (1); acrylic resin (2): a straight chain acrylic resin containing the structural unit (a) as the main component;
(a): a (meth)acrylate of the formula (A)
(wherein, R1 represents a hydrogen atom or methyl group, R2 represents an alkyl group having 1 to 14 carbon atoms or an aralkyl group having 1 to 14 carbon atoms, and a hydrogen atom in the alkyl group R2 or a hydrogen atom in the aralkyl group R2 may be substituted with an alkoxy group having 1 to 10 carbon atoms.),
(b): a monomer containing an olefinic double bond in the molecule and at least one 5- or more-membered heterocyclic group in the molecule, (c): a monomer containing at least two olefinic double bonds in the molecule.
