Abstract
The present invention provides a laminate excellent in abrasion resistance, high in hardness, and excellent in adhesion between a substrate and a primer layer and adhesion between an intermediate layer and a top coat layer. The laminate includes: a substrate; a primer layer disposed on the substrate, the primer layer containing inorganic particles (a1) having an average particle size of 3 μm or greater and a heat-resistant resin (a2), but not containing a fluororesin; an intermediate layer disposed on the primer layer and containing a fluororesin (b1) and a heat-resistant resin (b2); and a top coat layer disposed on the intermediate layer and containing a fluororesin (c1).
