Abstract
An adhesive for bonding together a first substrate made of vinylidene fluoride resin and a second substrate comprises an elastic fluorohydrocarbon resin, a polyisocyanate, and an organic solvent. This elastic fluorohydrocarbon resin is obtained by graft copolymerization of a fluorine-containing copolymer with a vinylidene fluoride monomer. This copolymer is prepared by copolymerizing at least one first fluorine-containing monomer with at least one unsaturated monomer that has peroxy bond. The adhesive itself is superior in durability, and bond strength between the first and second substrates is also superior.
