Abstract
Disclosed is a primer composition which contains an isocyanate compound having one or more 1,3,5-oxadiazine-2,4,6-trione rings as an adhesion promoter, which is useful as a primer for bonding polyester plastics to the same or different substrates using an adhesive such as polyurethane, epoxy and polyolefin adhesives. When the surface of polyester plastics is treated with said primer prior to application of the adhesive, the bonding achieved is excellent in adhesion.
