Application No. 09/333,917
Appealed Claim 1 Hari
“low-odor, cold-curing (meth)acrylate reaction polymerizable, cold-setting, reactive
resin for a floor coating, consisting of” (meth)acrylate system for conductive floor
coatings (col. 1, ll. 6-8); maximum amount
of styrene preferably limited to 20% by
wt. to avoid “considerable odor problems”
(col. 3, ll. 36-38)
“(A) (a) 50-100 wt% of a (meth)acrylate consisting (A) >50-100% by wt. of a monomeric
of component consisting essentially of
0-5 wt% of a methyl (meth)acrylate (meth)acrylate and/or other monomers,
0-5 wt% of an ethyl (meth)acrylate 0-100% by wt. methyl (meth)acrylate
0-97 wt% of a C3-C6 (meth)acrylate 0-100% by wt. C2-C4 (meth)acrylate
0-50 wt% of ≥C7 (meth)acrylate 0-50% by wt. ≥C5 (meth)acrylate
3-10 wt% of a multifunctional 0-100% by wt. polyhydric (meth)acrylates
(meth)acrylate; and and
(b) 0-50 wt% of a comonomer consisting of comonomers including the following:
0-30 wt% of a vinyl aromatic; and 0-30% by wt. vinyl aromatics
0-30 wt% of a vinyl ester” 0-30% by wt. vinyl esters (col. 2, ll. 39-
50)
“(B) 0-2 parts by weight per 1 part by weight of (B) 0-2 parts of a (pre)polymer which is
Component (A) of a pre-polymer that dissolves or soluble or capable of swelling in
swells in (A)” Component (A) for each part of (A) (col.
2, ll. 52-53)
“wherein the proportion of methyl (meth)acrylate 0-100% by wt. methyl (meth)acrylate
or ethyl (meth)acrylate is less than 5 wt% based 0-100% by wt. C2-C4 (meth)acrylate (col. 3,
on Component (B)” ll. 29-30)
“(C) 2-5 parts by weight per 100 parts by weight 0-7% by wt. of a plasticizer such as
based on Components (A) + (B) of at least one chlorinated paraffin; 0.05-5% by wt. of
paraffin and/or wax” paraffin (col. 4, ll. 41-58)
“(D) a redox system, containing an accelerator and (D) a redox system to be kept apart from
a peroxide catalyst or initiator in an amount that the polymerizable constituents of the
is adequate for cold-curing of Component (A)” system until polymerization is to be
carried out, at least in respect of one
component of the redox system, the redox
system containing an accelerator and a
peroxide catalyst or initiator in a
quantity sufficient for the cold-setting
of component (A) (col. 2, ll. 56-61)
“(E) optionally, at least one conventional (E) customary additives (col. 2, l. 62)
additive”
“wherein the multifunctional (meth)acrylate and most preferably 1-10% by wt. of
component (C) are together present in an amount polyfunctional (meth)acrylates (col. 4,
effective for the reaction resin, when applied to ll. 10-13; col. 4, ll. 54-64; col. 5, ll.
concrete at a thickness of approximately 1 cm and 64-66)
set at ambient temperature for 90 minutes, to be
non-tacky”
As seen from the table above, the appellants’ recited
relative amounts for each of the components including the
monomeric constituents are either substantially identical or
overlap significantly with those disclosed for Hari’s
