    Abstract: Moulded articles of polyolefins are dyed or printed with water-insoluble dyes that are soluble in organic solvents from aqueous dispersion or organic solution with either simultaneous or prior treatment with a dispersion or solution of a silicon hydrocarbon compound, an alkysiloxane, arylsiloxane, alkylarylsiloxane, alkylpolysiloxane, arylpolysiloxane, alkylarylpolysiloxane or an ester or polyester of silicic acid which silicon compounds are soluble in hydrocarbons. In Example 6 moulded articles of polyethylene are dyed with an aqueous liquor containing polydimethylsiloxane, a dispersed anthraquinone dye and surfactants and in Example 7 the same articles are printed with a solution in methylene chloride of hexyl-azo-naphthalene, tetraethylsilicate, nickel - II - oleate, triethanolamine and a linear polymer from ethyltriethoxysilane (80%) and phenyltriethoxysilane (10%).ALSO:Polyolefin materials are dyed or printed with water-insoluble dyes, which are soluble in organic solvents, from aqueous dispersion or organic solution in a process wherein the material is pretreated with a dispersion or solution of a silicon hydrocarbon compound, an alkylsiloxane, arylsiloxane, alkylarylsiloxane, alkylpolysiloxane, arylpolysiloxane, alkylarylpolysiloxane or an ester or polyester of silicic acid which silicon compounds are soluble in hydrocarbons, or wherein the dyeing or printing is carried out with the co-employment of any of the said silicon compounds. The so-treated material may then be subjected to a heat treatment. The polysiloxanes may be formed in situ with the help of catalysts, e.g. acids, bases or metal salts. The preferred polysiloxanes cross-link when the dye is fixed, again preferably in the presence of metal salts. Examples are given.
