Appeal No. 95-3865
Application 07/714,568
amendment dated Feb. 24, 1994 (Paper No. 13), was entered by the
examiner as noted in the Advisory Action dated March 18, 1994
(Paper No. 14). Therefore, the claims on appeal are claims 6-8,
12-20, 22, 26 and 27, which are the only claims remaining in this
application.
According to appellants, the invention is directed to a
presensitized plate useful in lithographic printing which
comprises a roughened and anodized aluminum support covered by a
positive working light-sensitive layer wherein the dye
concentration is lower in the portion of the layer adjacent to or
near the substrate than in the other portions of the light-
sensitive layer (brief, pages 2-3). As noted by appellants, the
use of these plates can significantly diminish color stain and
contamination during printing, without sacrificing printing
durability (brief, page 4).
Independent claims 26 and 27 are illustrative of the subject
matter on appeal and are attached as an appendix to this
decision.
The following references have been relied upon by the
examiner as evidence of obviousness:
