  • Patent number: 5504129
    Abstract: 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.

  • Patent number: 5104921
    Abstract: A cured composition possessing excellent cohesive strength at high temperatures along with excellent adhesion, shear strength and solvent resistance is prepared by the high energy ionizing radiation initiated curing of a polymer composition comprising an alkenyl arene/conjugated diene block copolymer and a oligomer such that the unsaturation index of the composition is minimized. The radiation initiated curing of the adhesive composition is accomplished without requiring the aid of a coupling agent to promote crosslinking of the block copolymer during exposure to the radiation.
