The Invention
The appellant's invention relates to a printing ink containing a binder, a process for preparing a
printing ink and a process for printing a substrate. (See claims 1, 6 and 11). A copy of the claims
under appeal is set forth in the appendix to the appellant's brief. Claim 1 is illustrative of the invention
and reads as follows:
1. A printing ink containing as a binder
A) a phenolic resin-modified rosin in a proportion of 60 to 90% by weight and
B) and alkyd resin in a proportion of 10 to 40% by weight, the sum of A) and B) giving 100% by
weight and the alkyd resin having been prepared from
a) an unsaturated fatty acid having 6 to 20 carbon atoms or a mixture of such acids or their
triglycerides;
b) a polyol, and
c) a dicarboxylic acid or anhydride thereof, said unsaturated fatty acid having an iodine number
of from 120 to 190 (g of I /100g) and the alkyd resin having a hydroxyl number of from 40 to 260 (mg
2
KOH/g) of resin and an acid number less than 11.
As with claim 1, we note that independent claims 6 and 11, while directed to processes for
making a printing ink and a process for printing on a substrate, require an alkyd resin prepared from an
