known in the art to depend upon the desired temperature for the
reaction” (col. 3, lines 49-52). One of Houser’s exemplified
free-radical polymerization initiators, di-tert-butyl peroxide
(col. 3, line 54), is among the appellant’s free-radical
polymerization initiators (specification, page 13, line 10).
Puschak discloses a printing ink composition comprising a
base and 1) a blend of a latex binder and a polyfunctional amine
and/or 2) an amine modified latex binder (col. 2, lines 42-57).
If desired, premature crosslinking or gelling of the latex binder
is induced by including 0.1 wt% to 25 wt% of multiethylenically
unsaturated monomers in the monomer mix used to form the binder
(col. 5, lines 1-5). The polymerization reaction used to form
the latex binder typically is initiated by conventional free
radical initiators (col. 5, lines 21-26).
Margotte discloses a process for producing a polyacrylate
resin having a residual acrylate monomer content of less than
0.1 wt%, based on resin solids, by preparing an initial
polyacrylate resin having a residual monomer content of about 0.5
to 3 wt% using an initiator which preferably has a half-life
between 0.5 minutes and 2 hours at the reaction temperature, and
subsequently polymerizing this resin in the presence of a monomer
