Appeal No. 1997-4310 Page 2
Application No. 08/371,362
Appellant’s invention relates to a method of treating
paper coated with a hot melt wax to disperse the wax and
converting the paper to pulp form. An understanding of the
invention can be derived from a reading of exemplary claims 46
and 57, which are reproduced below.
46. A method of repulping a paper coated with a hot melt
wax coating comprising the steps of:
(1) preparing a mixture of:
(a) a paper coated with said hot melt wax coating,
said coating comprising:
(1) at least one wax; and
(2) at least one chemical compound incorporated
in said at least one wax, said at least one
chemical compound capable of dispersing said
at least one wax in a substantially aqueous
environment; and
(b) water; and
(2) applying to said mixture an amount of mechanical
energy sufficient to convert said paper to a pulp form.
57. A method of dispersing wax from a hot melt wax-
coated paper, comprising the steps of:
introducing into a substantially aqueous environment a
paper having a hot melt coating thereon, said hot melt coating
comprising a wax and a chemical compound incorporated in said
wax which is capable of undergoing chemical modification so as
to be capable of dispersing said wax in said substantially
aqueous environment;
