    Abstract: Coloured leather or floor polishes based on at least one oil and/or at least one wax contain 2-30% by weight of an oil-soluble coloured copolymer. The polish may take the form of a paste comprising wax, coloured copolymer, and an organic solvent, or an aqueous dispersion comprising dispersed wax, coloured emulsion copolymer and an emulsifier. Suitable waxes are polyethylenes or oxidized polyethylenes, paraffin waxes, e.g. ozokerite, or animal or vegetable waxes, e.g. montan or oxidized and esterified montan wax, carnauba, beeswax or ceresine; alternatively oils or fats may be used. The copolymer may be composed of 70-99% by weight organic solvent - soluble monomer, 1-25% dyestuff with polymerizable olefinic group, and optionally up to 10% of a water-soluble monomer, the dyestuff preferably being an azo or anthraquinone derivative. Turpentine oil with or without white spirit may be employed as solvent for pastes, and for aqueous dispersions calcium stearate, silicone oils, an ethylene oxide sperm oil alcohol condensate, or a salt of an acid sulphuric acid ester of a polyethenoxylated branched aliphatic alcohol are used to assist emulsification. The pastes or dispersions may be formulated as aerosols using, for example, vinyl chloride, difluoro dichloro methane or tetrafluoro dichloroethane as propellant. Example 1 discloses an orange shoe cream containing, by weight, 10 parts polyethylene wax, M.W. 4000-6000, 1 part ozokerite, 10 parts paraffin wax, 74 parts turpentine oil, and 5 parts of a coloured copolymer obtained by solution polymerization of 5 parts of the coupling product of diazotized 2,4,5-trichloroaniline with N-ethyl-N-acryloyl-oxyethyl-m-toluidine, and 95 parts isooctyl acrylate in the presence of 3 parts azodiisobutyronitrile. Example 3 discloses a red shoe cream containing 7 pts. polyethylene, M.W. 4000-6000, 7 pts. esterified montan wax, 2 pts. ozokerite, 12 pts. paraffin wax, 65 pts. turpentine oil and 5 pts. of a copolymer of 5 pts. of an azo dyestuff and 95 pts. nonyl acrylate in the presence of 3 pts. azodiisobutyronitrile. Example 6 discloses an orange liquid floor polish containing 4.5 pts. polyethylene wax, M.W. 4000-6000, 0.5 pt. ozokerite, 5 pts. paraffin wax, 90 pts. turpentine oil and 5 pts. of the copolymer of Example 1.ALSO:Coloured leather or floor polishes based on at least one oil and/or at least one wax contain 2-30% by weight of an oil-soluble coloured copolymer.

Suitable waxes are polyethylenes or oxidized polyethylenes, paraffin waxes, e.g. ozocerite, or animal or vetetable waxes, e.g. montan or oxidized and esterified montan wax, carnauba, beeswax or ceresine; alternatively, oils or fats may be used.

Turpentine oil with or without white spirit may be employed as solvent for pastes, and for aqueous dispersions calcium stearate, silicone oil, an ethylene oxide-sperm oil alcohol condensate, or a salt of an acid sulphuric acid ester of a polyethenoxylated branched aliphatic alcohol are used to assist emulsification.

    Abstract: The present invention relates to an aqueous dispersion for the final dressing of leather, which consists essentially of a mixture of a) an aqueous emulsion of a nitrocellulose solution in organic solvents which are immiscible with water, liquid at the use temperature and sufficiently volatile at 100 to 150.degree.C containing 3 to 20% by weight based on the solution, of nitrocellulose and 10 to 100% by weight, based on nitrocellulose, of a plasticizer and further containing a non-ionic emulsifier, and b) an aqueous dispersion of a polyurethaneionomer with 0.02 to 0.2 percent of salt-like groups and wherein the ratio of a) to b), based on the weights of the aqueous emulsions or dispersions, is from 1:0.1 to 1:10.
