This invention relates to a crosslinking composition comprising a compound having the structure of Formula I: where Z is a hydrogen, an alkyl of 1 to about 18 carbon atoms, an aryl of about 6 to about 24 carbon atoms, an aralkyl of about 7 to about 24 carbon atoms, or -NR<SUB>2</SUB>R<SUB>2</SUB>; each R<SUB>2 </SUB>is independently hydrogen, an alkyl, aryl or an aralkyl of 1 to about 18 carbon atoms or R<SUB>3</SUB>; where R<SUB>3 </SUB>is -CHROR<SUB>1 </SUB>or where R is alkyl, halogenated alkyl, aryl, aralkyl, halogenated aralkyl, alkoxyalkyl or an alkaryl having from 1 to about 24 carbon atoms; R<SUB>1 </SUB>is a hydrogen, alkyl, aryl, aralkyl, alkoxyalkyl or an alkaryl having from 1 to about 24 carbon atoms; and where the alkyl or aryl groups in each radical may optionally have heteroatoms in their structure; B is a residue of a poly(alkylaldehyde) with n aldehyde groups; n is an integer of 2 to about 4; and A is an amino moiety derived from the group consisting of guanamine and melamine. The above composition may be prepared by reacting a melamine or guanamine with a mono(alkylaldehyde), a poly(alkylaldehyde) and an alcohol. |
