Patent ID: 8404779

Claim:
A kit comprising: a) at least one polyglycerol aldehyde having aldehyde groups, said polyglycerol aldehyde having a number-average molecular weight of about 400 to about 20,000 Daltons the general formula: wherein; A is either (a) a hydrocarbyl group derived by removing on or more hydroxyl groups from an alcohol or polyol containing 1 to 20 carbon atoms and 1 to 8 hydroxyl groups or (b) an oxahydrocarbyl or polyoxahydrocarbyl group derived by removing or or more hydroxyl groups from the reaction product of (I) an alcohol or polyol containing 1 to 20 carbon atoms and 1 to 8 hydroxyl groups and (II) one or more cyclic ethers, wherein the M n of the reaction product is less than or equal to 5,000 Da; R 1 is a hydrogen atom, a 1 to 8-carbon hydrocarbyl group, R 2 —O—[R 3 —CHO] p , or R 3 —CHO; R 2 is a polymeric segment comprising 1 to 270 glycerol units connected by ether linkages; R 3 is a hydrocarbylene group containing 1 to 8 carbon atoms; n=1 to 8; m*n=3 to 170; and p=1 to 40, wherein n, m and p are intergers; and an equivalent weight per aldehyde group of about 100 to about 3,000 Daltons; and b) at least one water-dispersible, multi-arm amine wherein at least three of the arms are terminated by at least one primary amine group, wherein the multi-arm amine has a number-average molecular weight of about 450 to about 200,000 Daltons.
