improved inherent surface lubricity to the radiation
sensitive layer (column 5, line 36 to column 6, line
51 and column 11, lines 58-68).
We find the examiner's stated obviousness rejection
problematical for at least the following reasons. First,
Hodakowski does not teach that the polydiorganosiloxane in his
composition functions as an “adhesion balance” controlling
compound but as a component which imparts “inherent surface
lubricity” to a coating. Thus, Hodakowski’s radiation curable
coating compositions are suited to forming external lubricious
coatings for metal sheets which undergo metal forming
operations and for forming coatings on a variety of other
substrates including panels of thermoplastic or thermoset
polymers. See Hodakowski at column 7, line 63 to column 8,
line 8. Hodakowski specifically teaches that the radiation
curable coating compositions may be applied over conventional
dry printing ink designs and cured to perform a protective
overprint, or that such coatings can be applied directly over
any of the known radiation curable inks. Again, see
Hodakowski at column 7, lines 63 to column 8, line 8.
Hodakowski, thus, is not directed to or concerned with a
tonable-radiation sensitive layer or of a tonable-radiation
