A process for producing compacted free-flowing nitrocellulose based lacquer raw materials is described. The process involves pressing a nitrocellulose based lacquer feed material, which is moistened with alcohol or water, through the holes of a die. The pressing step may be performed by means of at least one circulating breaker. The process optionally comprises shearing off the compacted lacquer raw material into pieces of selected length, below the die. The compacted nitrocellulose based lacquer raw materials prepared by the process of the present invention are free flowing and have a moisture content of at least 25%.

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.
