This is a decision on appeal from the examiner's final
rejection of claims 51 through 69, which are all of the claims
pending in this application.
The appellants' invention relates to a refinish primer
system comprising a first layer of refinish primer composition
that includes an organic solvent based dispersion and a second
layer of a primer surfacer composition. An understanding of
the invention can be derived from a reading of exemplary claim
63, which is reproduced below.
63. A refinish primer system comprising a first layer of
refinish primer composition and a second layer of primer
surface composition, said refinish primer composition
comprising;
an organic solvent based dispersion having a solids
content in the range from about 45 to 70%, by weight, wherein
said organic solvent is selected from the group consisting of:
aprotic solvents or mixtures thereof;
and wherein said solids comprise:
from about 10 to about 50%, by weight, crosslinked acrylic
polymer microparticles having a diameter of 0.1 to 10 microns
which are insoluble in the organic solvent and are stabilized
in the solvent system by steric barriers;
from about 30 to about 60%, by weight, an oxidatively-
curable resin;
from about 15 to about 40%, by weight, one or more
ingredients, selected from the group consisting of: corrosion
