Application No. 10/617,585
functional acrylate monomers and one or more functional methacrylate
monomers provided with said functional groups, and
wherein said crosslinking component for said crosslinkable groups
is selected from the group consisting of polyisocyanate, polyamine,
ketimine, melamine, epoxy, polyacid and a combination thereof.
5. The coating composition of claim 1 wherein said non-functional
acrylate monomer is provided with a non-functional group selected from
the group consisting of linear C1 to C20 alkyl, branched C3 to C20 alkyl,
cyclic C3 to C20 alkyl, bicyclic or polycyclic C5 to C20 alkyl, aromatic with 2
to 3 rings, phenyl and C1 to C20 fluorocarbon.
The coating composition comprises “crosslinkable” and “crosslinking”
components. The “crosslinkable component” is a “copolymer” which contains
“crosslinkable groups” and which is polymerized from non-functional acrylate
monomers and functional methacrylate monomers.
The “crosslinking component” “for said crosslinkable groups” is described
in the specification to have “crosslinking groups” which crosslink with the
“crosslinkable groups” during the curing step to form “crosslinked structures.”
Specification, page 5, lines 1-7. In other words, the two components
(crosslinkable and crosslinking) recited in the claims are chemically linked
together when the curing step is completed.
The crosslinking component is required by the claim to be “selected from
the group consisting of polyisocyanate, polyamine, ketimine, melamine, epoxy,
polyacid and a combination thereof.” The specification lists specific pairs of
crosslinking components and crosslinkable groups that are generally linked
together in the coating compositions. Id., page 9, line 24-page 10, line 4.
The copolymer contains “non-functional acrylate monomers” and
