<p num="1"><br/><br/><br/>This invention relates to a crosslinking composition comprising and organic <br/>acid and a compound having the structure of Formula I: A''-N RA-RDwhere A'' is a <br/>moiety derived from the group consisting of triazines, linear or cyclic ureas, <br/>cyanuric acid, substituted cyanuric acids, linear or cyclic amides, <br/>glycolurils, hydantoins, linear or cyclic carbamates and mixtures thereof, or <br/>a moiety comprising the structure (II):w here RA is RD, hydrogen, an alkyl of <br/>1 to 20 carbon atoms, or taken together with A'' forms a cyclic compound; RDis -<br/>CHRcORB, wherein RB is hydrogen, alkyl, aryl, aralkyl or an alkaryl having <br/>from 1 to about 24 carbon atoms and Rc is an alkyl, halogenated alkyl, aryl, <br/>aralkyl, halogenated aralkyl, alkoxyalkyl or an alkaryl having from 1 to about <br/>24 carbon atoms; A is a moiety derived from the group consisting of linear or <br/>cyclic ureas, cyanuric acid, substituted cyanuric acids, linear or cyclic <br/>amides, glycolurils, hydantoins, linear or cyclic carbamates and mixtures <br/>thereof; B is a residue of a poly(alkylaldehyde) with n aldehyde groups; n is <br/>an integer of 2 to about 8; Ra is Rd, hydrogen, an alkyl of 1 to about 20 <br/>carbon atoms, or taken together with A forms a cyclic compound; where Rd is <br/>CHRcORb or (III) where Rb is hydrogen, alkyl, aryl, aralkyl or an alkaryl <br/>having from 1 to about 24 carbon atoms and Rc is an alkyl, halogenated alkyl, <br/>aryl, aralkyl, halogenated aralkyl, alkoxyalkyl or an alkaryl having from 1 to <br/>about 24 carbon atoms; and where the alkyl or aryl groups in each radical may <br/>optionally have heteroatoms in their structure and to a process for producing <br/>the crosslinking.<br/>
