Abstract
To provide a powder primer composition excellent in adhesion properties and a laminate obtained by using it. The power primer composition comprises a powder made of a reactive ethylene/tetrafluoroethylene copolymer containing repeating units (A) based on tetrafluoroethylene, repeating units (B) based on ethylene, and repeating units (C) based on a monomer having an acid anhydride residue and a polymerizable unsaturated bond, wherein (C)/((A)+(B)) is from 1/10,000 to 5/100 by molar ratio; and a powder made of an epoxy resin having an epoxy equivalent of from 500 to 2,700 and a softening point of at least 70° C.; wherein the mass ratio of the powder made of a reactive ethylene/tetrafluoroethylene copolymer to the powder made of an epoxy resin is from 99/1 to 80/20.
