A two-part primer composition for MMA(methylmethacrylate) resin mortar is provided to perform the curing at a room temperature and to ensure adhesion to a material containing moisture removed by an isocyanate. A two-part primer composition for MMA(methylmethacrylate) resin mortar comprises a composition 1 and a composition 2. The composition 1 comprises a (meth)acrylate monomer, a (meth)acrylate polymer soluble in the (meth)acrylate monomer, two or more crosslinkable monomers, polyol, acidity-controlling agent and curing accelerator. The composition 2 comprises (meth)acrylate monomer, a (meth)acrylate polymer soluble in the (meth)acrylate monomer, and isocyanate.
