Abstract
Water-soluble crosslinkable compounds which are obtainable by reaction of reaction products, containing halogenohydrin groups, of ammonia or mono- or polyamines and an epihalogenohydrin or 1,3-dihalogeno-2-hydroxypropane with inorganic bases and subsequent reaction of the resulting compounds, which contain epoxy groups, with halogen-free acids or derivatives thereof to give compounds containing 1-acyloxy-2-hydroxypropyl groups are used for providing paper with a wet-strength finish, for aftertreatment of cellulose dyed with reactive and direct dyestuffs and for finishing wool.

Water-soluble crosslinkable compounds which are obtainable by a reaction of reaction products, containing halogenohydrin groups, of polyamines and an epihalogenohydrin or 1,3-dihalogeno-2-hydroxy-propane with inorganic bases and a subsequent reaction of the resulting compounds, which contain epoxy groups, with halogen-free mineral acids, mono- or polycarboxylic acids or derivatives thereof.
Process for the preparation of water-soluble crosslinkable compounds, comprising reacting reaction products, containing halogenohydrin groups, of polyamines and epihalogenohydrin or 1,3-dihalogeno-2-hydroxypropane with inorganic bases and then reacting the resulting compounds containing epoxy groups with halogen-free acids or derivatives thereof.
