Abstract

Abstract A hot melt, water remoistenable adhesive composition containing a water sensitive vinyl pyrrolidone-vinyl acetate copolymer, a plasticizer material which may include two different components, one of which operates as an adhesion promoter, and a wax component selected from the group consisting of Hoechst Wax S, peat wax, lignite wax and Castorwax. The composition may also include, in its preferred form, an antioxidant, an anti-block ingredient and/or a taste improving material.
