Photo-thermal dual curing of acrylic anchor resins for screen printing

Abstract Photo-thermal dual curing system was devised and applied to screen printing technology. New formulation of acrylic anchor resins contains a base polymer, which consists of hydrophilic units and solvent-absorbing units. As crosslinkers, multifunctional acrylates were employed. The acrylic anchor resins coated on poly(ethylene terephthalate) films were effectively cured by simultaneous photo-irradiation and baking below 80 °C. Printing resolution was strongly affected by the formulation of the acrylic anchor resins. An 8-μm feature size silver circuit was successfully printed without defect on a poly(ethylene terephthalate) film having the acrylic anchor layer.
