Appeal 2007-0296
Application 09/873,714
C) 2-10 weight-% of at least one compound having at least one
phosphoric acid group and containing at least one free-radically
polymerizable double bond, wherein the weight-% of component C) is
relative to quantity of the entire coating composition;
wherein said cured filler layer produces no edge marks when said topcoat
layer is applied.
8. The process according to claim 1, wherein the filler coating
composition comprises as component B) isobornyl (meth)acrylate.
The references set forth below are relied upon by the Examiner as
evidence of obviousness:
Richard US 5,091,211 Feb. 25, 1992
Brehm US 5,700,576 Dec. 23, 1997
Maag US 6,531,188 B1 Mar. 11, 2003
Claims 1-3, 6, 10, and 13 are rejected under 35 U.S.C. § 103(a) as
being unpatentable over Maag (i.e., DE-A-19757082 or WO 99/26733)1
in view of Richard, and claim 8 is correspondingly rejected over these
references and further in view of Brehm.
These rejections cannot be sustained for the reasons set forth below.
In rejecting claim 1, the Examiner concludes that it would have been
obvious to modify Maag's process of applying a filler coating composition to
a metal substrate by providing the composition with a phosphoric acid ester
in order to improve bond strength as taught by Richard (Answer 3-4). We
1 Concerning the disclosure of Maag, both the Examiner and the Appellants
rely on and refer to Maag's English language disclosure in US 6,531,188 B1.
We shall do likewise.
