THE INVENTION
Appellants’ claimed invention is directed toward a
crosslinked coating, a crosslinked sealant, and a crosslinked
adhesive, each of which is applied to a substrate and is
comprised of a dispersion having the same recited composition.
Claim 16 is illustrative and reads as follows:
16. A crosslinked adhesive comprising a dispersion which
is applied to a substrate, said dispersion comprising:
(a) 10 to 65% by weight of a polydiene block polymer
having a weight average molecular weight of from 2000 to
3,000,000 and containing at least five olefinic epoxy groups
per molecule which are sterically hindered,
(b) 0.2 to 25% by weight of a compatible aminoplast,
(c) 0.1 to 10% by weight of a surfactant which is
nonionic or anionic and has a volatile cation,
(d) 0.1 to 4% by weight of a proton-donating acid
catalyst, and
(e) the balance of water.
