ABSTRACT:
The addition of polyvinyl acetate to the core stock impregnating resin solution makes possible the preparation of relatively thin but yet strong plastic laminates which are also characterized by ready adhesion with contact adhesive without preparatory sanding and with only light sanding or roughening using less expensive adhesives. The materials so treated are also non-blocking.
