Resin composition

The present application relates to a resin composition comprising a polymer compound having an organic acid anhydride functional group, a two-component resin composition, and a battery module comprising the same. In the present application, it is possible to provide a resin composition in which a uniform mixing state can be maintained without any oil separation phenomenon and the like even in the composition in which a filler is blended, and there is no viscosity increase even when stored for a long period of time. In addition, the present application can provide a two-component resin composition comprising the resin composition, and a battery module comprising the resin composition or the two-component resin composition.
