(Problem) The resin composition which has a shrinkage | contraction rate at the time of hardening, has a high hardness, and gives the cured film which a curl and a crack does not generate | occur | produce, and the overcoating agent using this resin composition is provided. (Measures) (meth) acrylates other than urethane (meth) acrylate obtained by making glycerin (meth) acrylate (a) and an alicyclic polyisocyanate compound react, or glycerin (meth) acrylate (a) and (a) The resin composition containing urethane (meth) acrylate, (meth) acrylate, and a photoinitiator (C) obtained by making (a-1) react with a polyisocyanate (b). |
