Abstract
Provided herein is a process for surface treatment of moldings of liquid-crystalline polyester resin which comprises roughening with an alkaline aqueous solution the surface of moldings of melt-processable polyester capable of forming an anisotropic molten phase. The roughened moldings are activated by contacting with an aqueous solution of an ampholytic surface active agent such as an aminocarboxylate. The process is intended to provide the moldings with surface characteristics suitable for surface decoration such as printing, painting, metallizing, and plating and also for bonding with an adhesive.
