    Abstract: Polypropylene materials modified with basic compounds (less than 15%) are dyed or printed with water insoluble dyes (which may be metal complex dyes), containing at least one nitro group. Chromium and cobalt complex dyes are specifically referred to, dyeing is usually in neutral to weakly acid media pH 4-5, and at temperatures of 70-130 DEG C. Alternatively the material may be padded or printed at room temperature, dried at 70-100 DEG C. and steamed at 100 DEG C. or above or given a dry heat treatment at 110.130 DEG C. Conventional printing and dyeing assistants may be used.

    Abstract: Polypropylene containing 0.001% to 3.0% by weight of a metal compound capable of forming chelate complexes is dyed and/or printed using monoazo dyes of the general formula:- wherein X is hydrogen, a carboxylic acid group, an alkyl group or an aryl group; and Y is a radical derived from a coupling component free from ionic water solubilising groups, e.g. a phenol, enol, pyrazolone or an N, N\sv dialkylaniline radical free from complex forming groups. The Y radical may bear non-ionic substituents e.g. alkyl, cycloalkyl aryl, alkoxy, halogen or acylamino groups. The metals used which are present in the form of organic or inorganic compounds are Cr, Ni, Zn, Co, Cu, Cd and Al. Dyeing preferably at pH 4 to 5 using acetic acid may take place at 70 DEG - 130 DEG C from a long liquor or by impregnation with a short liquor at room temperature, drying at 70 DEG to 100 DEG C and then heating to 130 DEG C. The liquors may contain the conventional dispersing and emulsifying agents. Printing may take place by conventional film, screen or roller printing. Many examples of the dyes used are specified.

    Abstract: Coloured solution or aqueous dispersion polymers are obtained by copolymerization of dyes which contain a polymerizable olefinic group (chromophoric monomers), non-coloured polymerizable compounds which contain groups accessible to condensation or addition reactions as well as olefinic groups (reactive monomers) and, optionally, other known polymerizable compounds (inert monomers). The chromophoric monomers may be derived from dyes of the azo, anthraquinone, triarylmethane, phthalocyanine, phenazine and oxazine series and may contain a group of the formula: wherein R is a hydrogen or halogen atom, a lower alkyl, hydroxyalkyl, cyano, carboxy or carboxylic acid ester group, X is a hydrogen or halogen atom, an alkyl, substituted or unsubstituted aromatic radical and Y a hydrogen or halogen atom or an alkyl group. The polymerizable group may be attached to the dye molecule by way of a phenylene, -C(O)-, -SO2- or -NR1- radical, R1 being a hydrogen atom or an alkyl radical. Numerous suitable inert and reactive monomers are listed. Polymerization may be carried out by bulk, precipitation, emulsion, suspension or solution polymerization. Usual polymerization initiators may be used as well as the usual emulsifiers and protective colloids. The coloured polymers may be applied to textile materials of polypropylene in combination with number of other substances (see Division D2). In the examples copolymers are prepared from (1) butyl acrylate, butanediol monoacrylate, and 2, 4-dichloroaniline-->N-b -acryloylhydroxyethyl-N-ethylaniline in emulsion, (3) butyl acrylate, acrylonitrile, butanediol monoacrylate and 2-amino anisole-4-sulpho-n-butylamide--> N-ethyl-N-b -acryloyloxyethylaniline in emulsion, (4) butyl acrylate ethyl acrylate, N-methylol-methacrylamide and the dye from (1) in emulsion, (6) butyl acrylate, methyl methacrylate, N-methylolmethacryl-amide and N-acryloyl-p-phenylenediamine--> 1-(2-chloro-5-sulphophenyl)-3-methyl-5-pyrazolone in emulsion, (7) butyl acrylate, acrylonitrile, methyl methacrylate, N-methylolmethacrylamide and the dye from (6) in emulsion, (8) butyl acrylate, acrylamide, methyl methacrylate, butanediol monoacrylate and 2, 4-dichloroaniline--> N-ethyl-N-vinyloxy-ethylaniline in ethanol solution and (9) methyl methacrylate, butyl acrylate, acrolein, the dye from (1) in ethanol/toluene solution. Specifications 830,876, 858,183, 875,946 and 877,402 are referred to.ALSO:Textile materials of polypropylene are coated with solutions or aqueous dispersions of a coloured polymer obtainable by copolymerization of chromophoric monomers (i.e. dyes which contain a polymerizable olefinic group) with uncoloured polymerizable compounds at least some of which also contain groups capable of entering into cross-linking reactions (reactive monomers), and cross-linking the copolymers after application either alone or with the aid of suitable bi- or poly-functional compounds. The chromophoric monomers may be based on dyes of the azo, anthraquinone, triarylmethane, phthalocyamine, phenazine and oxazine series which contain a polymerizable group of the formula in which R is a hydrogen or halogen atom, a lower alkyl, hydroxyalkyl, cyano, carboxy or carboxylic acid ester group, X is a hydrogen or halogen atom, an alkyl or a substituted or unsubstituted aromatic radical and Y is a hydrogen or halogen atom or an alkyl group and in which the polymerizable group is attached to the dyestuff molecule by way of a phenylene, -C(O)-, -SO2- or -NR1-radical where R1 is a hydrogen atom or an alkyl group. Numerous reactive and inert monomers are specified as are suitable cross-linking agents which include hexamethylenediisocyanate and its bisulphite compound, N,N1-dimethylol - butanediol - 1,4 - diurethane, tetramethylolacetylene - tetramethylolacetyleneurea and its tetrabutyl ether. Cross-linking without a cross-linking agent may be accomplished by raising the temperature or changing the pH. Numerous suitable catalysts are specified. The cross-linking agents and/or catalysts may be applied before, after or with the coloured copolymer. The coated fabric may be dried and heated to 110-200 DEG C. to effect the cross-linking. The coloured copolymers may also be used together with other resins, e.g. aminoplasts and water-soluble natural, synthetic and semi-synthetic substances such as starches, cellulose ethers, vegetable gums and polymers of carboxylic acids or their salts or amides. Non-woven fabrics of polypropylene may be prepared with the present copolymers which then act as binding agent and dye. With the aid of embossing rollers or graining presses artificial leathers may be prepared. Specifications 830,876, 858,183, 875,946 and 877,402 are referred to.ALSO:Textile materials of polypropylene are simultaneously dyed and finished by treatment with solutions or aqueous dispersions of a coloured polymer obtainable by copolymerization of chromophoric monomers (i.e. dyes which contain a polymerizable olefinic group) with uncoloured polymerizable compounds at least some of which also contain groups capable of entering into cross-linking reactions (reactive monomers), and cross-linking the copolymers after application either alone or with the aid of suitable bi- or poly-functional compounds.
