Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
61 words
A surface coating composition containing a polymeric binder, the binder comprising on a weight basis: between about 5% and 60% polyol containing two or more hydroxyl groups, between 2% and 60% glycoluril, and between 10% and 80% emulsion polymer, said emulsion polymer being emulsion copolymerized ethylenic monomers, said binder composition being heat curable and thermosetting to form a cured coating film.
Claim 2
Dependent Claim
61 words
A surface coating composition containing a polymeric binder, the binder comprising on a weight basis: between about 5% and 60% polyol containing two or more hydroxyl groups, between 2% and 60% glycoluril, and between 10% and 80% emulsion polymer, said emulsion polymer being emulsion copolymerized ethylenic monomers, said binder composition being heat curable and thermosetting to form a cured coating film.
Claim 3
Dependent Claim
22 words
The coating composition in claim 1 wherein the emulsion polymer contains reactive functional monomer selected from acrylamide, carboxyl, or hydroxyl containing monomer.
Claim 4
Dependent Claim
38 words
The coating composition in claim 1 wherein the emulsion polymer contains at least 10% by weight copolymerized functional monomers comprising 1% to 20% acrylamide or methacrylamide monomer, 0.5% to 10% carboxylic monomer, and 0% to 20% hydroxyalkyl monomer.
Claim 5
Dependent Claim
13 words
The composition in claim 3 wherein the acrylamide monomer is an N-alkanol amide.
Claim 6
Dependent Claim
14 words
The composition in claim 1 wherein the polyol contains three or more hydroxyl groups.
Claim 7
Dependent Claim
13 words
The composition in claim 1 as a polymer binder system for coating wood.
