A resin composition may contain: a (meth)acrylic copolymer containing a structural unit (A) based on a specific metal atom-containing polymerizable monomer (a) and a structural unit (B) based on a specific polysiloxane block-containing polymerizable monomer (b); and an organic solvent, wherein a content of the structural unit (A) is from 5 to 35 mass %, a content of the structural unit (B) is from 35 to 75 mass %, and a content of the structural unit based on a (meth)acrylic macromonomer is less than 13 mass % relative to a total mass of all structural units constituting the (meth)acrylic copolymer, a weight-average molecular weight of the (meth)acrylic copolymer is 2000 or more and 6500 or less, and a VOC content is 500 g/L or less.
