Appeal No. 1996-0575
Application No. 08/219,551
Claims 22 and 23 are illustrative of the subject matter on appeal and are
reproduced below:
22. A thermosettable paint composition suitable for application from a solid block
thereof as a hot melt to a substrate heated to a temperature which is hot enough to melt a
surface portion of said solid block upon contact therewith, said composition comprising:
a pigment; and
A thermosettable mixture of resins, having an averaged glass transition
temperature (Tg) of greater than -30EC and less than +60EC and having a melt viscosity of
from about 0.1 to 12 poise when measured at 180EC and at a shear rate of 10,000 Hz;
wherein said mixture of resins comprises:
a first resin having a glass transition temperature T of greater than
g
+20EC, and
a second resin having a glass transition temperature T of below
g
+20EC and a melt viscosity of 0.1 to 7 poise when measured at 180EC and at a shear rate
of 10,000 Hz,
wherein said pigment is dispersed in said first resin and this dispersion is
admixed with at least said second resin to make said solventless paint composition.
23. A method of manufacture of a thermosettable solventless paint composition,
having the ability to be applied as a hot melt from a solid block comprising said
composition onto a substrate in contact with said block which substrate has been heated
to a temperature hot enough to melt a surface portion of said solid block within the time
that said substrate is in contact with said block, comprising the steps of:
(i) selecting a first resin having a glass transition temperature (T ) greater than
g
+20EC,
