Pre-etch treatment of acrylonitrile-butadiene-styrene resins for electroless plating
Abstract
Abstract AQUEOUS SOLUTION ARE PROVIDED CONTAINING AT LEAST ONE FIVE-MEMBERED HETEROCYCLIC COMPOUND HAVING A NUCLEAR CARBONYL GROUP AND AT LEAST ONE HETEROCYCLIC OXYGEN ATOM. THE SOLUTIONS ARE USED PRIMARILY AS A PRE-TREATMENT PRIOR TO ETCHING FOR THE ELECTROLESS METAL PLATING OF ACRYLONITRILEBUTADIENE-STYRENE RESINS (ABS RESINS) TO IMPROVE ADHESION BETWEEN AN ABS RESIN SUBSTRATE AND A DEPOSITED ELECTROLESS METAL. AN OVERALL PROCESS FOR METAL PLATING ON ABS SUBSTRATE WOULD INCLUDE THE STEPS OF PRE-ETCHING WITH THE SOLUTION OF THIS INVENTION, OXIDIZING WITH A STRONG OXIDIZING AGENT, PREFERABLY, A CHROMIC ACID CONDITIONING SOLUTION HAVING A HIGH HEXAVELENT CHROMIUM CONTENT, CATALYZING THE SO-TREATED SUBSTRATE TO MAKE THE SAME CATALYTIC TO DEPOSITION FROM AN ELECTROLESS PLATING SOLUTION AND DEPOSITING ELECTROLESS METAL OVER THE SUBSTRATE.
