    摘要： Aqueous coating agent dispersions comprisingA. from 3 to 30% by weight of cellulose nitrate,B. from 10 to 50% by weight of at least one liquid prepolymer, which is optionally emulsifiable in water even in the absence of emulsifier, which contains from 0.01 to 1.3 mols/100 g of prepolymer of polymerizable C--C double bonds,C. from 0 to 25% by weight of at least one liquid prepolymer, which is not emulsifiable in water in the absence of emulsifier, which contains from 0.01 to 1.3 mols/100 g of prepolymer of polymerizable C--C double bonds and has a maximum acid value of 25 and a maximum viscosity at 23.degree. C. of 60 Pa.s,D. from 0 to 20% by weight of an organic solvent with an evaporation number of 0.
