  • Patent number: 4847316
    Abstract: Compositions useful as printing inks or as dry or wet concentrates for the preparation of inks, comprising substantially homogenous blends of from about 0.1 to about 50.0 wt. % water dispersible polyurethane, and conversely from about 99.9 to about 50.0 wt. % water dispersible polyester, and preferably containing from about 1.0 to about 95.0 wt. % of a solvent system comprising water or water admixed with cosolvent, the cosolvent comprising up to about 30.0 wt. % of the solvent system. These blends show exceptionally marked improvements in certain physical properties such as: stability of viscosity to ambient and process conditions; linearity of viscosity change with water dilution; consistency of viscosity for a great variety of pigments; and greatly improved shelf-life (no significant polymer segregation of layering). Such properties greatly enhance the utility of these blends for use in pigmented or dyed printing inks and in other substrate coating formulations which may or may not contain colorants.

  • Patent number: 4839230
    Abstract: The present invention relates to a grafted cellulose ester prepared by reacting a cellulose ester containing residual hydroxyl groups with an acrylic based compound and m-isopropenyl-.alpha.,.alpha.'-dimethylbenzyl isocyanate. The grafted cellulose ester is a urethane-containing product having pendant (meth)acrylate and .alpha.-methylstyrene moieties. The grafted cellulose ester is readily self-polymerizable in the presence of a photoinitiator upon exposure to ultraviolet radiation. It does not require the presence of vinyl monomers to become crosslinked. The grafted cellulose ester is useful as a protective/decorative coating for wood, metal, plastics, and other substrates.

  • Patent number: 4801668
    Abstract: Processes for the preparation of low non-transannular, high softening point hydrocarbon resins from 1,5-cyclooctadiene are disclosed. In one aspect of the invention, 1,5-cyclooctadiene is heated in the presence of an aluminum halide catalyst at temperatures at or above 80.degree. C. to give the desired resin. In another aspect of the invention, 1,5-cyclooctadiene is combined with a copolymerizable olefin in the presence of an aluminum halide catalyst at temperatures ranging from 30.degree. C. to 250.degree. C. The high softening point resins produced by these processes have levels of non-transannular impurities below 20% by weight, and these resins are particularly useful as wetting or bonding agents for coatings, adhesives, and other applications.
