ABSTRACT:
A method of etching a surface of a body including the steps of applying a suitable modified epoxy thermo-setting adhesive coating to an etchant resisting masking film; punching the masking film in a predetermined pattern corresponding to the pattern to be etched on the body; applying the masking film to a major surface of the body to be etched, thereby exposing a portion of the major surface corresponding to the predetermined pattern; setting the adhesive coating by applying heat so that the masking film is securely attached to the body; and subsequently applying an etchant to the body covered by the making film so that the predetermined pattern is etched into the major surface of the body.
