  • Dry erase ink composition
    Patent number: 6031023
    Abstract: Novel white board dry erase ink compositions are provided which are comprised of poly(oxyalkylene) substituted colorants, volatile solvent vehicles, and binder resins. The binder resin is insoluble within the alcohol of the volatile vehicle; however, the degree of alkoxylation on the colorant aids in solubilizing the binder resin within the entire solution. Once the composition is transferred to a white board, the solvent evaporates, leaving the binder resin and colorant as a friable discontinuous film which is easily removed from the writing surface. The inventive composition has improved erasability, writability, stability within the marker stylus, and washability from skin and fabrics. Markers and methods of producing the ink composition are also provided.

  • Polymer-modified, acid dyeable polyester and polyolefin textile materials and method for producing same
    Patent number: 4171404
    Abstract: A composition for improving the acid dyeing properties of polyester or polyolefin materials, as well as the adhesion properties of such materials to vinyl coatings, such composition being the reaction product of a polyamide and a polyepoxide having at least two 1,2-epoxy groups per molecule. Application of the composition to polyester or polyolefin materials is set forth as is a vinyl-coated, acid-dyed, polymer modified polyester or polyolefin textile material.
