    • An oil-in-water coating agent is described. The coating agent emulsion is prepared from a composition comprising: a) 5.0 to 50 wt. % of cellulose substance; b) 5.0 to 50 wt. % of at least one hydroxyl group-containing lacquer resin; c) 2.0 to 25 wt. % of at least one polyisocyanate having more than one free isocyanate group; d) 10.0 to 65 wt. % of water; e) 0.5 to 30 wt. % of plasticiser; f) 0.0 to 20 wt. % of emulsifier; and g) 0.0 to 45 wt. % of at least one organic solvent. The sum of components a) to g) of the composition is 100 wt. %, and the weight ratio of hydroxyl groups of the hydroxyl group-containing lacquer resin b) to NCO groups of the polyisocyanate c) is 1:0.05 to 1:5. Also described is a method of using the coating agent emulsion, and its application to the surface of materials, such as wood and metal.
