The adhesive comprises 50 to 90 wt % of ethylene-vinyl acetate copolymer having a hydrolysis ratio of 50 to 90 wt %, 5 to 30 wt % of polyamide resin having an amine value of 0.5 to 15, and 5 to 30 wt % of styrene-butadiene-styrene block copolymer of styrene-isoprene-styrene block copolymer containing less than 30 wt % of styrene, mixed together.
The heat-recoverable article having a layer of the adhesive is prepared by applying said adhesive to at least one part of the surface of a heat-recoverable article made from a rubber, a plastics or a mixture thereof.
