Abstract: A reaction product and process for increasing the wet strength of paper which comprises adding to a slurry of paper fibers selfcross-linking water soluble reaction products prepared from a) epihalohydrins and/or Alpha -dihalo-hydrins such as epichlorohydrin, b) water soluble basic polyamides such as that formed by the reaction of diethylene-triamine and adipic acid, and c) water soluble polyamines such as bis-(3-amino-propyl)amine which contain at least two nitrogen atoms separated from one another by at least three carbon atoms and optionally also by oxygen or sulfur atoms, and contain at least two hydrogen atoms attached to different nitrogen atoms wherein the components b) and c) are used in a proportion of 1-10:1 and component a) is used in an amount of 0.5 to 1.5 mole per basic amino group.
