    Abstract: A pigment binder suitable for dyeing and printing processes consists of a mixture of a polymer bearing halohydrin groups in side chains and a compound containing at least two epoxy groups in the molecule. From 0.025 to 0.5 part by wt. of the polyepoxide is used per part of the polymer. The polymer may be an aqueous emulsion polymer containing 0.5 to 30% by wt. of an acrylic or methacrylic ester which contains a halohydrin group in the ester radical and from 95.5 to 70% by wt. of one or more comonomers. The epoxy compounds used may be glycidyl ethers of polyols containing halohydrin groups. Pigment dyeing or printing is carried out by curing the composition. The composition may also contain a vat, sulphur or reactive dye and/or a coupling agent.ALSO:A pigment binder suitable for pigment printing processes is a mixture of a polymer bearing halohydrin groups in side chains and a compound containing at least two epoxy groups in the molecule (e.g. a glycidyl ether of a diol or polyol). From 0.025 to 0.5 parts by wt. of the polyepoxide are used per part of the polymer. The pigment printing composition may also contain a vat, sulphur or reactive dye and/or a coupling agent. Examples relate to the printing of cotton, cotton/polyester and glass fabrics. The printed fabrics may be dried, e.g. at 50 DEG C. and the printing fixed by curing, e.g. for 5 minutes at 140 DEG C. in hot air.
