Abstract
A solution that can be used for trapping at least one toxic chemical agent, the solution comprising at least one protic solvent, at least one monomer comprising an (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide group, at least one crosslinking agent comprising at least two groups chosen from the (alkyl)acrylic, (alkyl)acrylate or (alkyl)acrylamide groups, at least one photopolymerization initiator, at least one thixotropic filler and at least one agent chosen from alkali metal halides, alkali metal phosphates, alkali metal sulfates and mixtures thereof.
