Appeal No. 96-0641
Application No. 08/004,890
remaining in the application.
The subject matter on appeal relates to an aqueous resin
composition comprising an oxazoline group-containing polymer,
a carboxyl group-containing polymer and an acidic compound-
amine salt catalyst which is formed from at least one acid
selected from the group consisting of phosphoric acid,
phosphorous acid, hydrochloric acid, sulfuric acid, nitric
acid and an organic sulfonic acid. The appealed subject
matter also relates to a curing process which utilizes the
aforementioned composition. This subject matter is adequately
illustrated by independent claim 3 which reads as follows:
3. An aqueous resin composition comprising in an aqueous
medium an oxazoline group-containing polymer (A), a carboxyl
group-containing polymer (B), and an acidic compound-amine
salt catalyst (C) in an amount of from 0.1 to 10% by weight
based on the total weight of the oxazoline group-containing
polymer (A) and the carboxyl group-containing polymer (B), the
acidic compound from which the acidic compound-amine salt
catalyst (C) is formed being at least one acid selected from
the group consisting of phosphoric acid, phosphorous acid,
hydrochloric acid, sulfuric acid, nitric acid and an organic
sulfonic acid.
