摘要:
The present invention provides a laminated article having improved adhesion of the fluorine-containing resin layer to the elastomer layer. The laminated article comprises a fluorine-containing resin layer (a) formed using a fluorine-containing resin having a carbonyl group, an olefin group or an amino group at an end of a polymer trunk chain or an end of a polymer side chain, and an elastomer layer (b) formed using an elastomer composition.
