Patent ID: 6984451

Claim:
A process for providing a structure having a modified surface property; said process comprising: applying an acylated polymeric polyamine to a surface of a structure to obtain said structure having a modified surface property, wherein said modified surface property comprises a hydrophilic surface property, and wherein from 5 to 100% of the nitrogen atoms comprised in said acylated polymeric polyamine, based on the total number of nitrogen atoms in said acylated polymeric polyamine, bear an acyl radical represented by formula I R 1 —CO— (I) wherein R 1 is hydrogen, C 1 –C 27 -alkyl, C 7 –C 27 -alkenyl or C 6 –C 10 -aryl, wherein C 1 –C 27 -alkyl, C 7 –C 27 -alkenyl and C 6 –C 10 -aryl optionally comprise at least one substituent selected from the group consisting of hydroxyl, alkoxy, alkoxycarbonyl and NE 1 E 2 , wherein E 1 and E 2 are independently hydrogen, alkyl or acyl, and the weight-average molecular weight of said acylated polymeric polyamine is from 1,000 to 1,000,000.
