    Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.

    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.

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: Leather is simultaneously dyed and finished by treatment with an aqueous solution or dispersion comprising (I) a polymer having reactive groups X, (II) one or more dyes having reactive groups Y and, optionally (III) a cross-linking component having at least two reactive groups Z per molecule and allowing the components to react at 20 - 120 DEG C in the presence of an acid or alkaline catalyst, where the number of groups Y is less than the number of X and the amount Y + Z being approximately equal to X, the groups X being possibly alkylated N-methylolamide groups and Y and Z being the same or amino or amido groups or vice versa as complementary pairs. Suitable catalysts are ammonium nitrate or ammonium chloride while numbers of suitable compounds (I), (II) and (III) are specified. The components may be applied together or in sequence by brushing, dipping, spreading, spraying or drumming and the subsequent heating may be carried out in drying chambers or hot grain embossing rolls. Examples are given.
