Patent ID: 7381347

Claim:
A crosslinking composition comprising the structure of Formula I: A′-NR A —R D (Formula 1) wherein A′ represents a moiety from Group 2 optionally mixed with a moiety from Group 1; wherein Group 1 consists of: a mono or divalent moiety derived from melamine or guanamine; and Group 2 consists of: (a) a monovalent or divalent moiety of a compound selected from linear ureas, cyclic ureas, cyanuric acid, substituted cyanuric acids, linear amides, cyclic amides, glycolurils, hydantoins, linear carbamates, cyclic carbamates and mixtures thereof, and (b) a moiety of Formula 2: R A is selected from: R D , hydrogen, C 1-20 alkyl, and where R A taken together with A′ is a divalent moiety (together forming a cyclic compound when attached to the nitrogen in Formula 1); R A is selected from divalent R D , a bond and C 1-20 alkylene; R D is <—CHR C OR B , wherein R B is selected from: C 1-24 alkyl, C 3-24 aryl, C 4-24 aralkyl and C 4-24 alkaryl; and R C is selected from: optionally halogenated C 1-24 alkyl; C 3-24 aryl, optionally halogenated C 4-24 aralkyl; C 2-24 alkoxyalkyl, and C 4-24 alkaryl, and A is a monovalent or divalent moiety of a compound selected from: linear ureas, cyclic ureas, cyanuric acid, substituted cyanuric acids, linear amides, cyclic amides, glycolurils, hydantoins, linear carbamates, cyclic carbamates and mixtures thereof; B represents a mixture of residues from propionaldehyde and from glutaraldehyde; R a is selected from: R d , hydrogen, C 1-20 alkyl and where R a taken together with A forms a cyclic compound; and R b selected from: C 1-24 alkyl, C 3-24 aryl, C 4-24 aralkyl and C 4-24 alkaryl; wherein R d is selected from: a radical <—CHR c OR b and a moiety of Formula 3: R c is selected from: optionally halogenated C 1-24 alkyl ; C 3-24 aryl; optionally halogenated C 4-24 aralkyl; C 2-24 alkoxyalkyl; and C 4-24 alkaryl; and wherein the alkyl and aryl groups in each radical may optionally have heteroatoms in their structure.
