    摘要: IN AN ACIDIC CONDITIONING BATH CONTAINING (A) A STRONG, LIQUID MINERAL ACID, (B) A HEXAVALENT CHROMIUM COMPOUND AND (C) WATER, FROM ABOUT 0.01% TO ABOUT 5% BY WEIGHT OF AN ARYL SULFONIC ACID OR AN ARYL PHOSPHONIC ACID IS ADDED TO THE AFOREMENTIONED CONDITIONING BATH COMPONENTS. THE ACIDIC CONDITIONER IS USEFUL FOR CHEMICALLY ETCHING THE SURFACE OF A PLASTIC ARTICLE PRIOR TO TREATING THE ARTICLE WITH A METALLIZING PROCESS. ADHESION OF THE DEPOSITED METAL TO THE SURFACE OF THE PLASTIC ARTICLE IS IMPROVED WHEN THE PLASTIC ARTICLE IS IMMERSED IN THE ACIDIC CONDITIONING BATH.
