water-based coating composition, method of forming a tissue-like coating on a substrate, use of a water-based coating composition, and coated substrate

摘要

The present invention relates to a water based coating composition. The composition according to the present invention comprises an emulsified binder, wherein the binder is a polymer selected from the group consisting of polymers prepared by emulsion polymerization of unsaturated vinyl, acrylate and / or methacrylate monomers, alkyl, polyurethane and epoxy, 0.3% to 10% by weight of a second polymer selected from one or more of the group consisting of (poly) vinyl alcohol and water soluble copolymers with vinyl alcohol repeat units, where, the second polymer is (poly) vinyl alcohol, at least 85% by weight of the second polymer has a number of repeating units of not less than 2,000, and 0 to 15% by weight of cellulose-based filler based on total weight of the composition, wherein the weight ratio of the second polymer to the binder is in the range 1: 100 to 1: 1. The composition may be used in various applications to form a decorative coating that has a special visual and tactile effect.
