Claims 1, 2, 4-8 and 11-13 stand rejected under 35 U.S.C.
§ 103(a) as being unpatentable over Kado in view of Lehr,
Mochizuki, Maslanka and Nakashima; the remaining claims on appeal
stand correspondingly rejected over these references and further
in view of the other previously listed references relied upon by
the examiner.
We refer to the brief and to the answer for a complete
exposition of the opposing viewpoints expressed by the appellants
and by the examiner concerning the above noted rejections.
OPINION
For the reasons which follow, we cannot sustain any of these
rejections.

(2) N-methylolacrylamide monomer, and (3) quaternary ammonium
monomer such as methacryloloxyethylammonium chloride (col. 5,
lines 28-68, and col. 7, lines 41-49, 53, and 57)” (answer, pages
