Abstract
A wax emulsion is provided which comprises as essential ingredients (A) 100 parts by weight of a petroleum fraction wax having a melting point ranging within 40.degree. to 90.degree. C.; and (B) 3 to 20 parts by weight of an oxygen containing wax; said oxygen-containing wax being prepared by mixing 10 to 80 parts by weight of a petroleum fraction wax (I) having a melting point ranging within 50.degree. to 85.degree. C. with 90 to 20 parts by weight of a polyolefin wax (II) having a melting point ranging within 36.degree. to 120.degree. C., a number average molecular weight of from 310 to 1,000 and 5 to 50 double bonds per 1,000 carbon atoms to obtain a mixture, and then reacting 100 parts by weight of said mixture with 3 to 25 parts by weight of an unsaturated polycarboxylic acid or an anhydride thereof under a condition for forming free radicals.
