Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
65 words
A coating composition suitable for application to a substrate which coating composition comprises a partially fluorinated polyvinyl acetal resin and polysilicic acid, in which the ratio by weight of polysilicic acid, calculated as SiO 2 , to partially fluorinated polyvinyl acetal resin is from 1.5:1 to 5:1 and in which the partially fluorinated polyvinyl acetal contains from 0.1 to 10 percent by weight of fluorine.
Claim 2
Dependent Claim
65 words
A coating composition suitable for application to a substrate which coating composition comprises a partially fluorinated polyvinyl acetal resin and polysilicic acid, in which the ratio by weight of polysilicic acid, calculated as SiO 2 , to partially fluorinated polyvinyl acetal resin is from 1.5:1 to 5:1 and in which the partially fluorinated polyvinyl acetal contains from 0.1 to 10 percent by weight of fluorine.
Claim 3
Dependent Claim
22 words
The coating composition of claim 1 in which the partially fluorinated acetal contains from 0.1 to 3 percent by weight of fluorine.
Claim 4
Dependent Claim
14 words
The coating composition of claim 1 in which the polyvinyl acetal is polyvinyl butyral.
Claim 5
Dependent Claim
28 words
The coating composition of claim 1 in which the partially fluorinated polyvinyl acetal comprises acetal groups in which all the hydrogen atoms have been replaced by fluorine atoms.
Claim 6
Dependent Claim
23 words
The coating composition of claim 1 in which the SiO 2 partially fluorinated polyvinyl acetal resin weight ratio is from 2:1 to 4:1.
Claim 7
Dependent Claim
35 words
The coating composition of claim 1 in which the partially fluorinated polyvinyl acetal is a partially fluorinated polyvinyl butyral having a hydroxyl content, calculated as polyvinyl alcohol, of from 30 to 45 percent by weight.
Claim 8
Dependent Claim
57 words
A coating composition suitable for application to a substrate which coating composition comprises a partially fluorinated polvinyl butyral resin containing from 0.1 to 5 percent by weight of fluorine and polysilicic acid, in which the ratio by weight of polysilicic acid, calculated as SiO 2 , to partially fluorinated polyvinyl acetal resin is from 2:1 to 4:1.
Claim 9
Dependent Claim
57 words
A coating composition suitable for application to a substrate which coating composition comprises a partially fluorinated polvinyl butyral resin containing from 0.1 to 5 percent by weight of fluorine and polysilicic acid, in which the ratio by weight of polysilicic acid, calculated as SiO 2 , to partially fluorinated polyvinyl acetal resin is from 2:1 to 4:1.
Claim 10
Dependent Claim
34 words
The coating composition of claim 7 in which the partially fluorinated polyvinyl butyral is a polyvinyl butyral in which from 1 to 5 percent of the butyral groups have been replaced by perfluorobutyral group.
Claim 11
Dependent Claim
11 words
A substrate coated with a coating composition according to claim 1.
Claim 12
Dependent Claim
11 words
A substrate coated with a coating composition according to claim 9.
