Pliable, aqueous processable, photopolymerizable permanent coating for printed circuits

摘要

Aqueous processable photopolymerizable compositions containing (a) a cobinder system, (b) an acrylated urethane monomeric component; (c) a photoinitiator system; and (d) a thermal cross-linking agent are disclosed, which as cured compositions, are flexible and can be used as permanent coatings for the protection of printed circuitry.
