Abstract
The present invention provides a resin composition for an insulating film which resin composition is excellent in tack property after drying and allows a resultant insulating film to be excellent in flexibility and electrical insulation reliability and to be small in warpage after curing, a resin film for an insulating film, an insulating film, and a printed wiring board provided with an insulating film. The resin composition for an insulating film contains at least: a (A) binder polymer; and (B) cross-linked polymer particles, whose polymer has a urethane bond and a carbonate skeleton in its molecule.
