8 . The hydrophilic monomer according to claim 1 , obtained from reacting at least one polyoxyalkylamine with at least one acrylate compound.

9 . The hydrophilic monomer according to claim 8 , wherein the polyoxyalkylmine is a polyetherdiamine comprising ethoxy-units and propyloxy-units.

10 . The hydrophilic monomer according to claim 9 , wherein the ratio of ethoxy-units to propyloxy-units EO:PO is in the range of from 1 to 20.

11 . A process for producing a hydrophilic monomer, comprising reacting at least one polyoxyalkylamine with at least one acrylate compound; wherein the hydrophilic monomer comprises (i) at least one amino moiety; (ii) at least one polyoxyalkyene unit; and (iii) at least one acrylate moiety, wherein the at least one amino moiety isa at least one secondary amino moiety and/or at least two tertiary amino moieties.

12 . The process according to claim 11 , wherein the at least one polyoxyalkylamine is selected from polyetheramines.

13 . The process according to claim 11 , wherein the polyoxyalkylamine exhibits a molecular weight in the range of from 80 g/mol to 8000 g/mol.

14 . Coating obtained from the hydrophilic monomer according to claim 1 by coating hydrophilic monomer onto a substrate and curing the coating by actinic irradiation.

15 . The hydrophilic monomer according to claim 1 , wherein the at least one acrylate compound is selected from alkyldiacrylates, alkyltriacrylates, alkyltetraacrylates, alkylpentaacrylates, alkyl hexaacrylates, polyethylene glycol diacrylates, ethoxylated trimethylolpropane triacrylates, and trimethylolpropane triacrylate.
