    摘要: Repulpable, hot melt adhesives which are composed of approximately equal amounts of a tackifier (having an acid number greater than about 70) and a hydrophilic wax, with up to 9% of polymer. The hot melt compositions can contain up to 17% of polymer when the tackifier has a higher acid number of about 140.

    摘要: The specification discloses an aqueous dispersion for coatings consisting essentially of water and a water dispersible component, wherein the water dispersible component is provided by reacting maleic anhydride with a rosin ester to provide a maleated rosin ester, adding wax and preferably also an ethylene vinyl acetate copolymer to the maleated rosin ester, and adding a tertiary amino alcohol to the mixture to yield the water dispersible component as a reaction product thereof. When used in a coating formulation for paper, clay and/or latex may be added to the formulation. In one preferred embodiment, the dispersion is applied as a coating to paper to enhance toner adhesion to the surface of the paper while also providing a relatively low friction surface.
