1. A shelf stable, air-curing composition comprising an

endblocked with autoxidizable end groups, said polyformaldehyde
chain having from 1 to 14 formaldehyde units and being liquid and
soluble in the acetoacetate polymer, stored in the absence of
atmospheric oxygen.
7. The composition of Claim 1 wherein the acetoacetate
functionality on the polymer is reversibly converted to enamine
for storage, using ammonia or volatile amine.
The references relied on by the examiner are:
Gresham et al. (Gresham) 2,449,469 Nov. 2, 1944
Bors et al. (Bors) 4,960,924 Oct. 2, 1990
The claims are rejected as follows:
I. Claims 1 through 7 are rejected under 35 U.S.C. § 112,
first paragraph, as the disclosure is only enabling for claims
limited to compositions containing a metal drier.
II. Claims 1 through 6, 8 and 9 are rejected under 35 U.S.C.
§ 103 as being unpatentable over Bors in view of Gresham and
Huyser.
We have carefully considered the entire record which
includes, inter alia, the specification, the appellants’ Brief
(Paper No. 12) and the examiner’s Answer (Paper No. 13). We
agree with the examiner that the specification is enabling only
