  • Patent number: 10047241
    Abstract: This invention provides hydrophobic compositions for forming hydrophobic toner receptive coatings on a substrate. The hydrophobic coating compositions for forming toner receptive coatings on a substrate contain a hydrophobic polymer comprising: (a) a N-vinyl amide monomer, (b) a non-reactive hydrophobic monomer moiety, and (c) a solvent. The coating compositions may further comprise (d) a substituted or unsubstituted monomer comprising a cyclic ether or an acetoacetate, or mixtures thereof. The invention also provides compositions suitable for addition to toner to enhance adhesion and toner substrates coated with the hydrophobic coating compositions. The hydrophobic polymer may be represented by the following structure, wherein x, y, z, and a, are defined herein.
