Abstract
The process for crosslinking cellulosic fiber materials, especially cellulosic fiber materials which are 20 to 100% by weight natural or regenerated cellulose fibers, comprises applying to the cellulosic fiber materials in which the cellulosic fibers comprise natural or regenerated cellulose at least one product of the general formula (1) ##STR1## where A is a colorless aliphatic, aromatic or heteroaromatic radical, R is a fiber-reactive radical and n is 1, 2, 3 or 4, with the proviso that the radical [R].sub.n includes at least two fiber-reactive groups, and is useful for achieving permanent finish effects, for example in the area of easy care, dimensional stability and shrink resistance.
