Appeal No. 1997-2070 Application 08/487,921 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 -7-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
