Abstract
The present invention relates to a composition for forming a coating layer having a self-healing property which enables the provision of a film exhibiting further improved mechanical properties together with excellent self-healing properties by being applied to the exterior of various household appliances or display devices, etc., a coating layer and a film. The composition for forming a coating layer having a self-healing property comprises: a poly(Calkylene glycol)-modified polyfunctional urethane (meth)acrylate-based binder; a bifunctional or higher polyfunctional (meth)acrylate-based compound; a UV initiator; and a silica nanoparticle, wherein the binder has a trifunctional or higher urethane bond and each poly(Calkylene glycol)-modified (meth)acrylate-based compound is bound to the urethane bond in the binder, and at least two poly(Calkylene glycol)-modified (meth)acrylate-based compounds bound to each urethane bond include poly(Calkylene glycol) repeating units whose numbers of repetitions are different from each other.
