Abstract
A primer composition is provided that includes a reactant having an alkoxysilyl group, the reactant being obtained by reacting a polyisocyanate (I), an isocyanate group, and an alkoxysilane having a reactable functional group; a polyisocyanate (II); a polyurethane compound; a (meth) acrylic resin; and a solvent. In the primer composition, a molecular weight of the (meth) acrylic resin is from 15,000 to 150,000 and a weight ratio [(meth) acrylic resin/polyurethane compound] of the (meth) acrylic resin to the polyurethane compound is from 90/10 to 10/90. Additionally, a laminate is provided that includes an inorganic material and a primer layer obtained from the primer composition.
