    Abstract: Fibrous materials, especially of cellulose, are printed with a pigment print paste containing as binder a film-forming polymer which may be fixed by alkalis and also printed with a print paste containing a vat, sulphur or reactive dye and the prints are finished off in the usual way. The preferred mode of operation comprises printing the pigment paste and then the dyestuff paste, drying, impregnating with an alkaline liquor containing a reducing agent when vat or sulphur dyes are used, squeezing, steaming at 100-140 DEG C. and finishing. The preferred polymers contain groups having chlorohydrin groups, e.g. by copolymerising 2-hydroxy-3-chloro-propylacrylate or 2, 3-dichloro-4-hydroxy-butylmethacrylate with other copolymerisable monomers (many listed). A number of known alkaline agents and reducing agents are specified. Examples are given.

    Abstract: Coloured copolymers are prepared by polymerizing (a) a metal complex of an azo dye containing at least one polymerizable, olefinically unsaturated group in the molecule, and (b) at least one uncoloured, olefinically unsaturated comonomer. Monomer (a) may be a 1 : 1 or 1 : 2 metal complex of an azo dye having the formula in which A and B are each a divalent benzene or naphthalene ring system or a divalent heterocyclic aromatic ring system, at least one of the radicals R1 and R2 is a vinyl group, acryloyl group, acryloylamino group, acryloyloxy group or a group having the formula in which n has a value from 1 to 6, and if only one of the radicals R1 and R2 is one of the said groups, the other is a hydrogen atom, halogen atom, nitro group, cyano group, sulphonic group, sulphonic ester group or sulphonamide group, and X1 and X2 are each a hydroxy group, carboxylic group, or primary or secondary amino group located in ortho-position to the azo group. The central atom in the monomer complex may be copper, cobalt, nickel, chromium or iron (such dye complexes being illustrated in Specification 885,814). Polymerization may be effected in solution or emulsion using initiators such as potassium persulphate, hydrogen peroxide, benzoyl peroxide or redox systems. Examples illustrate the emulsion polymerization of some 1 : 1 and 1 : 2 cobalt azo dye complexes, the comonomers being selected from acrylic acid, ethyl acrylate, n-butyl acrylate, methyl methacrylate, methacrylamide, N - methylol - methacrylamide and vinylidene chloride. Specifications 877,402, 885,814, 914,354 and 949,404 are referred to.

    Abstract: Coloured packaging material in the form of sheets or containers made from organic plastics consists of or comprises an organic addition polymer containing a dye linked therewith by a covalent chemical bond. The dye containing addition polymer may be a copolymer of a colourless monomer and a dye containing a polymerizable group, preferably a vinyl group, or may be the reaction product of a polymer containing reactive groups and a dye having a group reactive therewith, and may be prepared by the processes described in Specifications 622,935, 877,402 and 946,472. Innocuous plasticizers, fillers and pigments may be incorporated and sheets prepared by casting from solution, aqueous dispersion or a melt. Bags, bottles, beakers, boxes and tubes may be prepared by injection moulding, and the polymers may be laminated to or used for impregnating paper or cardboard. The sheets and containers may be used for packaging solid and liquid foodstuffs, pharmaceuticals, tinctures, cosmetic preparations and chemical reagents and solvents. In examples (1) sheets are calendered from a copolymer prepared by suspension copolymerization of vinyl chloride and N-acryloylaminoazobenzene in the presence of partially saponified polyvinyl acetate, azodiisobutyronitrile and sodium pyrophosphate; and (2) boxes are obtained by deep drawing sheets extruded from a mixture of a suspension copolymer of styrene and acrylonitrile and a copolymer obtained by initiating the copolymerization of vinyl methyl ether and the product obtained by coupling N-acryloylamino-p-aminobenzene and 1-(2-chloro-5-sulphophenyl) -3- methyl-pyrazolone -5, in aqueous dispersion in the presence of sodium paraffin sulphonates, potassium persulphate, sodium bicarbonate and sodium pyrophosphate, and adding butyl acrylate, acrylonitrile and butane diol diacrylate when polymerization has commenced.
