Appeal No. 95-3734
Application No. 08/043,620
the application, stand withdrawn from further consideration by
the examiner as directed to a non-elected invention.
THE INVENTION
The invention relates to a class of interpenetrating polymer
networks which are dispersible in conventional coating solvents.
According to appellants, such dispersions are useful in preparing
protective and/or decorative film coatings and are particularly
useful in photosensitive or imaging formulations such as photo
resists, sodder masks, and the like.
Claims 1 and 99, which are illustrative of the subject
matter on appeal, read as follows:
1. A composition of matter comprising an interpenetrating
polymer network containing at least two polymer networks which
(a) are polymerized and/or crosslinked in the immediate
presence of one another, and
(b) are dispersible in a solvent with the proviso that at
least one of the polymer networks is formed by
polymerization in a solvent and that one of the
following takes place in formation of two polymer
networks:
(i) the two polymer networks are formed sequentially
wherein the second polymer network is formed in a
solvent dispersion of the first formed polymer
network, or
(ii) the two polymer networks are formed simultaneously
or substantially simultaneously by independent and
non-interfering mechanisms of polymerization.
[Emphasis added].
