Appeal No. 1996-3931
Application No. 08/198,336
1. An adhesive composition for wet lamination of substrates,
comprising:
from about 40 weight percent to about 65 weight percent
solids dispersed in an aqueous medium, wherein the solids
comprise:
a polymer having first repeating units derived from a
vinyl ester monomer, having second repeating units derived
from a (C -C )alkyl (meth)acrylate monomer and having a glass
1 12
transition temperature of -15°C to about +15°C; and
from about 0.1 parts by weight to about 40 parts by
weight of a plasticizer compound per 100 parts by weight of
the polymer.
As evidence of obviousness, the examiner relies upon the
following references:
Weist et al. (Weist) 4,322,516 Mar. 30, 1982
Weist et al. (Canadian ‘895) 1 141 895 Feb. 22, 1983
(Canadian Patent)
The appealed claims stand rejected under 35 U.S.C. § 103
as unpatentable over Weist or Canadian ‘895.
We cannot sustain the stated rejection.
The subject matter on appeal is directed to an aqueous
adhesive composition for wet lamination of substrates having
from about 40 weight percent to 65 weight percent solids
dispersed in an aqueous medium. The solids component of the
claimed composition comprises a polymer having repeating units
