Appeal No. 2001-0825
Application No. 08/952,566
1. A thermoset paint composition, comprising:
(a) from 20 to 70% by weight of a fluorine
containing copolymer comprising the result of
copolymerizing
at least one fluoro-olefin monomer,
at least 10% by weight of one or more hydroxy
group containing vinyl monomer having at least four
atoms between a vinyl group and a hydroxy group, and a
terminal hydroxy group, the percent by weight based on
the total weight of copolymer (a), and
one or more other vinyl monomers,
the fluorine containing copolymer (a) having a
solubility parameter from 9.0 to 10.5 and a hydroxy
group value from 60 to 150 mgKOH/g,
(b) from 20-70% by weight of a vinyl (co)polymer
comprising the result of copolymerizing at least one
vinyl monomer, said at least one vinyl monomer
comprising at least 10% by weight of one or more
monomers represented by the general formula 1
wherein R1 to R5 each independently represent H or
methyl group, i is 0-2, j is 0 or 1, k is 0-3, m is 0-
3 and n is 0-10,
the vinyl (co)polymer [sic] (b) having a
solubility parameter from 9.0 to 10.5 and a hydroxy
group value from 60 to 150 mgKOH/g,
(c) from 5 to 40% by weight of alkyl etherified
melamine resin, and
(d) from 2 to 40% by weight of blocked
polyisocyanate compound, wherein all percents by
weight are based on the total weight of the resin
components (a) to (d) the thermoset paint composition
providing a paint film having a glass transition
temperature after hardening of at least 50°C.
4. The thermoset paint composition of claim 1
which is a topcoat.
