| titleOfInvention | Improvements relating to low temperature pigment binder compositions and their use in coloring textile material |
| abstract | Aqueous pigment preparations suitable for pad dyeing and printing textile material comprise 0.025 to 2% by weight of the composition of a latent acid catalyst, a water-insoluble pigment and a binder containing (a) 90 to 10% by weight of a soft latex component obtained by the polymerization of 2 to 10% by weight of methacrylic acid, 60 to 85% by weight of butadiene and 38 to 5% by weight of acrylonitrile or styrene, and (b) 10 to 90% by weight of a hard latex component containing a water-insoluble linear polymer of 1 to 25% by weight of a compound of formula <FORM:0954587/C3/1> where R is hydrogen or a C1-4 alkyl group and R1 and R2 are hydrogen or alkyl groups, and 99 to 75% by weight of at least one alkyl acrylate or methacrylate containing 1 to 8 carbon atoms in the alkyl group. Preferably (b) comprises a cross-linking agent obtained by the reaction of an aliphatic aldehyde of not more than 4 carbon atoms with urea, thiourea, biuret, melamine or derivatives thereof and optionally an alkanol of not more than 2 carbon atoms. Specified latent acid catalysts are ammonium nitrate, thiocyanate, sulphate and chloride, diammonium hydrogen phosphate and morpholine and pyridine salts of mineral acids. The cross-linking agent may be the reaction product of formaldehyde, acetaldehyde, glyoxal or propanedial, and optionally methanol or ethanol, with urea, N,N-ethylene urea, N,N1-ethylene urea, N,N1-dimethylurea, N,N1-diethylurea, melamine or N,N-dimethylmelamine. The preparations may also contain wetting agents, e.g. alkaryl sodium sulphonates and ethylene oxide condensates with octyl and nonyl phenols. Examples describe preparations comprising an aqueous pigment concentrate containing phthalocyamine blue, sodium lauryl sulphate, sodium diisopropyl naphthalene sulphonate, casein, methyl cellulose, butylated melamine formaldehyde condensate, antifoam agent, xylene and mineral spirits; an aqueous extender comprising casein, sodium lauryl sulphate, ammonium lauryl sulphate, methyl cellulose, butylated melamine formaldehyde condensate, ammonium hydroxide and mineral spirits and binders comprising (1) a copolymer of methacrylic acid, butadiene and acrylonitrile, a copolymer of methacrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl monomethylol melamine and ammonium nitrate; (2) a copolymer of methacrylic acid, butadiene and styrene, a copolymer of acrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl urea and ammonium thiocyanate; and (3) a copolymer of methacrylic acid, butadiene and acrylonitrile, a copolymer of N-methyl methacrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl monomethylol melamine and diammonium phosphate.ALSO:Textile materials may be pad dyed and printed with aqueous pigment preparations comprising 0.025 to 2% by weight of the composition of a latent acid catalst, a water-insoluble pigment and a binder containing (a) 90 to 10% by weight of a soft latex component obtained by the polymerisation of 2 to 10% by weight of methacrylic acid, 60 to 85% by weight of butadiene and 38 to 5% by weight of acrylonitrile or styrene, and (b) 10 to 90% by weight of a hard latex component containing a water-insoluble linear polymer of 1 to 25% by weight of a compound of formula CH2 = <FORM:0954587/D1-D2/1> where R is hydrogen or a C1-4 alkyl group and R1 and R2 are hydrogen or alkyl groups, and 99 to 75% by weight of at least one alkyl acrylate or methacrylate containing 1 to 8 carbon atoms in the alkyl group. Preferably (b) comprises a cross-linking agent obtained by the reaction of an aliphatic aldehyde of not more than 4 carbon atoms with urea, thiourea, biuret, melamine or derivatives thereof and optionally an alkanol of not more than 2 carbon atoms. Specified latent acid catalysts are ammonium nitrate, thiocyanate, sulphate and chloride, diammonium hydrogen phosphate, and morpholine and pyridine salts of mineral acids. The cross-linking agent may be the reaction product of formaldehyde, acetaldehyde, glyoxal, or propanedial, and optionally methanol or ethanol, with urea, N, N-ethylene urea, N, N1-ethylene urea, N, N1-dimethylurea, N, N1-diethylurea, melamine or N, N-dimethylmelamine. Examples describe the printing with compositions comprising an aqueous pigment concentrate containing phthalocyanine blue, sodium lauryl sulphate, sodium diisopropylnaphthalene sulphonate, casein, methyl cellulose, butylated melamine formaldehyde condensate, antifoam agent, xylene and mineral spirits; an aqueous extender comprising casein, sodium lauryl sulphate, ammonium lauryl sulphate, methyl cellulose, butylated melamine formaldehyde concentrate, ammonium hydroxide and mineral spirits and binders comprising (1) a copolymer of methacrylic acid, butadiene and acrylonitrile, a copolymer of methacrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl monomethylol melamine and ammonium nitrate on cotton, polyamide, polyester and cotton and acrylic fabrics; (2) a copolymer of methacrylic acid, butadiene and styrene, a copolymer of acrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl urea and ammonium thiocyanate on polyester, polyamide and cotton/acetate blend fabrics; and (3) a copolymer of methacrylic acid, butadiene and acrylonitrile, a copolymer of N-methyl methacrylamide, methyl methacrylate and ethyl acrylate, dimethoxymethyl monomethylol melamine and diammonium phosphate on cotton/acetate blend, silk and polyamide fabrics. The prints are cured by heating. |
