发明名称 Protein/starch paper coating compositions and method of use thereof
摘要 Improved compositions for coating paper stock, methods of forming such compositions, and methods of coating paper stock with those compositions are provided. The compositions comprise an aqueous dispersion including therein from about 20-45% by weight filler (e.g., a starch such as wheat starch) and from about 6-18% by weight wheat gluten. Preferably, the gluten is initially modified with a reducing agent so that the average molecular weight of the gluten is less than about 1,000 kDa. The compositions have a viscosity of up to about 2000 cP and a solids content of from about 25-57% by weight, thus making them suitable for high speed coating of paper stock. The finished, coated stock may be conventionally printed to achieve high gloss end products. The compositions are preferably water soluble, thereby greatly facilitating repulping of the coated stock.
