ABSTRACT:
A plastic substrate is processed by a functional water obtained by electrolysis of water or functional water containing active oxygen or active hydrogen for a predetermined time period to selectively remove an alkali and/or halogen component in a surface layer of the plastic substrate to stabilize or remove oligomer in a resin matrix, whereby deterioration of resin and deterioration of properties of a recording medium caused by a remaining unreacted catalyst used for processing the plastic substrate surface or the like can be prevented and the adhesion strength and the durability of a recoding coating to be formed on the substrate are improved.
