Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
In an air drying coating composition comprising a resinous binder, the improvement wherein the resinous binder comprises a mixture of (A) 9% to 91% by weight of a silicone-modified alkyd resin, a silicone-modified acrylic-grafted alkyd resin and/or a silicone-modified acrylic resin, the silicone modification of the alkyd, acrylic-grafted alkyd and acrylic resins being achieved by reacting said resin with a silicone resin having a reactive group selected from hydroxyl and alkoxy in the molecule and (B) 91% to 9% by weight of a carboxyl group-containing chlorinated polyolefin resin.
Claim 2
Dependent Claim
88 words
In an air drying coating composition comprising a resinous binder, the improvement wherein the resinous binder comprises a mixture of (A) 9% to 91% by weight of a silicone-modified alkyd resin, a silicone-modified acrylic-grafted alkyd resin and/or a silicone-modified acrylic resin, the silicone modification of the alkyd, acrylic-grafted alkyd and acrylic resins being achieved by reacting said resin with a silicone resin having a reactive group selected from hydroxyl and alkoxy in the molecule and (B) 91% to 9% by weight of a carboxyl group-containing chlorinated polyolefin resin.
Claim 3
Dependent Claim
26 words
The composition of claim 1 wherein the proportion of the silicone component is 5 to 57% by weight based on the weight of the resin mixture.
Claim 4
Dependent Claim
41 words
The composition of claim 1 wherein the silicone-modified alkyd resin and the silicone-modified arcylic-grafted alkyd resins have an oil length of 15 to 60%, a silicone content of 20 to 60% by weight, and an acid value of 5 to 30.
Claim 5
Dependent Claim
20 words
The composition of claim 1 wherein the silicone content of the silicone-modified acrylic resin is 20 to 50% by weight.
Claim 6
Dependent Claim
26 words
The composition of claim 1 wherein the carboxyl group-containing chlorinated polyolefin resin is a carboxyl group-containing chlorinated polyethylene resin and/or a carboxyl group-containing chlorinated polypropylene resin.
Claim 7
Dependent Claim
20 words
The composition of claim 1 wherein the carboxyl group-containing chlorinated polyolefin resin has an acid value of 5 to 30.
Claim 8
Dependent Claim
36 words
The composition of claim 1 wherein the silicone resin employed to achieve modification is selected from the group consisting of ##STR4## R is alkyl, ##STR5## φ is phenyl; n is 0-2, and ##STR6## φ is phenyl.
