We agree that Vieira suggests that biocides and antistatic
agents are conventional additives for recording mediums.
Consequently, we find that the addition of such biocides and
antistatic agents to the recording medium of Miyamoto would
have been obvious to one of ordinary skill in the art for the
purposes that their names suggest. Therefore, we agree with
the examiner that claims 25 and 26 would have been obvious
