Abstract

See full text

A multifunctional polymerizable ionic liquid is described comprising an anion and a cationic group having at least two ethylenically unsaturated polymerizable groups, each bonded to the cationic group via a divalent non-alkyl linking group. The multifunctional linking groups independently comprise a heteroatom such as oxygen or nitrogen. The linking groups may independently comprise one or more linkages such as an amide, urea, or ether linkage and more typically a urethane or ester linkage. The ethylenically unsaturated polymerizable groups are typically (meth)acrylate groups. Coatings and coated articles are also described.
