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.

Dry erase ink composition

A mixture of diphenols is provided of the general formula: ##STR1## wherein the mixture comprises three components as follows; (a) from about 2% to about 35% by weight of compound A corresponding to formula (I) wherein R.sub.1 and R.sub.6 are H; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are selected from H and Br; and --X-- is selected from CH.sub.3 --C--CH.sub.3, --S--, or --O--;

Liquid, non-crystallizing two mole diphenol alkoxylate mixtures

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.

Polymer-modified, acid dyeable polyester and polyolefin textile

A method for improving the elasticity of a textile material is provided wherein a preshrunk textile material, while maintained in a relaxed state, is impregnated with a liquid admixture consisting essentially of a polyisocyanate, a polyether diol, and a polyether polyol having at least three hydroxyl groups per molecule, reacting the polyisocyanate with the polyether diol and polyether polyol to provide a polymeric impregnated textile material, and curing the polymeric impregnated textile material to provide a textile material having improved elasticity.
