Heat-activated adhesive comprising a pressure-sensitive-adhesive acrylate polymer and a tackifying resin, the latter being included in sufficient amount to lower the pressure-sensitive adhesion of the complete heat-activated adhesive to levels needed for convenient and effective room-temperature handling of sheets coated with the adhesive, while leaving the adhesive with the capacity for strong heat-activated bonds.

Heat-activated adhesive comprising (a) an acrylate polymer capable of room-temperature pressure-sensitive adhesion of at least 100 grams per centimeter width; and (b) room-temperature-solid tackifying resin that provides increased room-temperature tackiness when added in at least some amounts to said acrylate resin or natural rubber, but which is included in said heat-activated adhesive in an amount sufficient to reduce room-temperature pressure-sensitive preadhesion of the adhesive to less than the pressure-sensitive adhesion of the acrylate polymer prior to addition of the tackifying resin.
