ABSTRACT:
A two-layer adhesive coating having a dry, non-tacky surface convertible to a permanently adhesive surface by application of heat. A first co-reactant in an adhesive-containing base layer combines with a second co-reactant applied to the base layer to form a dry, non-tacky barrier layer comprising a molecular complex which dissociates upon heating to form a permanently adhesive surface.
