Abstract
Water-soluble crosslinkable compounds obtainable by reaction of reactive products which contain halogenohydrin groups and have been obtained by reacting polyamines and epihalogenohydrin or 1,3-dihalogeno-2-hydroxy-propane with inorganic bases and subsequently reacting the resulting products with inorganic acids and/or organic acids, can be used as pigment binders and/or crosslinking agents in textile printing pastes.
Claims18
A process for pigment printing on fibre materials in which a pigment is fixed to a fibre material with a binder, wherein said binder is a binder comprising:
- A) a basic polyamidoamine and
- B) a crosslinking agent which is obtained by reaction of a polyamine with epihalogenohydrin or 1,3-dihalogeno-2-hydroxy-propane, followed by reaction with an inorganic base and further followed by stabilization with an acid selected from the group consisting of inorganic acids, carboxylic acids and mixtures thereof.
