Abstract
Abstract A UV curable, etch-resistant ink composition for ink jet printing of variable information on printed circuit boards and for printing the circuit boards themselves comprising a resin formulation having at least two acrylate components, one of which is an acrylate having a pendant carboxyl group and one of which is an acrylated epoxy monomer or dimer, a photoinitiator and an organic carrier. Also, methods for printing variable information on printed circuit boards and for printing the circuit boards themselves utilizing a UV curable, etch-resistant ink composition.
