Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 80 words
A coated article comprising: a substrate, and coated thereon a composition comprising a crosslinked product of: a polyester-amide, and a melamine resin; wherein, said polyester-amide comprises the polycondensation product of: one or more C 2-20 dicarboxylic acids or an activated derivative thereof, 2,2-bis(4-hydroxyphenyl)hexafluoropropane, and an aminoalkyl-terminated organopolysiloxane of the formula, ##STR3## wherein, R 1 and R 2 are independently C 1-16 alkylene; R 3 -R 6 are independently C 1-6 alkyl, vinyl or phenyl; and a is 3 to 300.
Claim 2
Dependent Claim 80 words
A coated article comprising: a substrate, and coated thereon a composition comprising a crosslinked product of: a polyester-amide, and a melamine resin; wherein, said polyester-amide comprises the polycondensation product of: one or more C 2-20 dicarboxylic acids or an activated derivative thereof, 2,2-bis(4-hydroxyphenyl)hexafluoropropane, and an aminoalkyl-terminated organopolysiloxane of the formula, ##STR3## wherein, R 1 and R 2 are independently C 1-16 alkylene; R 3 -R 6 are independently C 1-6 alkyl, vinyl or phenyl; and a is 3 to 300.
Claim 3
Dependent Claim 17 words

Dependent Claim 14 words
A coated article according to claim 1, wherein R 3 -R 6 are methyl.
Claim 5
Dependent Claim 22 words
A coated article according to claim 1, wherein at least one of said dicarboxylic acids is a C 8-20 aromatic dicarboxylic acid.
Claim 6
Dependent Claim 15 words
A coated article according to claim 4, wherein said aromatic dicarboxylic acid is isophthalic acid.
Claim 7
Dependent Claim 22 words
A coated article according to claim 1, wherein at least one of said dicarboxylic acids is a C 2-10 alkylene dicarboxylic acid.
