Abstract
Abstract Gluestick adhesive compositions for adhesively securing together two substrates comprise a solution or dispersion of an adhesive of N-vinyl-pyrrolidone polymer or co-polymer and wax acids, or esters of such acids with alcohols having one to eight carbon atoms, in sufficient amount for the composition to be moulded in stick form as a self-supporting gel.
