Appeal No. 1999-0697 Page 2
Application No. 08/743,151
Appellant's invention relates to a hot melt wax coating
and a paper coated therewith. All of appellant’s claims
require that the coating includes: (1) about 50-90%, by
weight, of a paraffin wax, microcrystalline wax, or mixture
thereof; (2) about 10-30% of at least one chemical compound,
which compound is capable of dispersing the wax in an aqueous
environment or capable of being chemically modified to so
disperse the wax; and (3) a specified thermoplastic polymeric
material. Appellant discloses that stearic acid is a chemical
compound that could be chemically modified to so disperse the
wax. According to appellant, a paper coated with such a
coating composition may be repulped in an aqueous environment
(specification, page 9, last paragraph). Claim 1 further
illustrates the subject matter on appeal and is reproduced
below.
1. A hot melt wax coating composition comprising:
from about 50-90% by weight of at least one wax selected
from the group consisting of paraffin wax and microcrystalline
wax,
from about 10-30% of at least one chemical compound
incorporated in said at least one wax which is capable of
undergoing chemical modification so as to be capable of
dispersing said at least one wax in a substantially aqueous
environment, and
