Abstract:
Coating compositions that can provide grease and oil resistant coating for substrates, especially paper and textile substrates, are disclosed. The coating compositions comprise water insoluble α-(1,3→glucan) polymer and/or dextran polymer and optionally other additives.

Claim (Index 9):
A method comprising:\n 1) providing an aqueous coating composition comprising A) water insoluble \u03b1-(1,3\u2192glucan) polymer having 90% or greater \u03b1-1,3-glycosidic linkages, less than 1% by weight of \u03b1-1,3,6-glycosidic branch points and a number average degree of polymerization in the range of from 55 to 10,000 in aqueous alkali metal hydroxide and/or B) dextran in water wherein the dextran comprises:\n (i) 87-93% \u03b1-1,6 glycosidic linkages; \n (ii) 0.1-1.2% \u03b1-1,3-glycosidic linkages; \n (iii) 0.1-0.7% \u03b1-1,4-glycosidic linkages; \n (iv) 7.7-8.6% \u03b1-1,3,6-glycosidic linkages; and \n (v) 0.4-1.7% \u03b1-1,2,6-glycosidic or \u03b1-1,4,6-glycosidic linkages; \n wherein the weight-average molecular weight (Mw) of the dextran is about 50-200 million Daltons, the z-average radius of gyration of the dextran is about 200-280 nm; and \n 2) applying a layer of the aqueous coating composition to at least a portion of a substrate; and 3) removing at least a portion of the water from the applied layer; wherein the dried layer of coating composition forms a continuous layer on the substrate.
