Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
58 words
A silicone-modified water-based coating composition consisting essentially of a mixture of: (A) a water-based coating composition; and (B) a suspension of a plurality of silicone rubber particles in water, the content of said silicone rubber suspension (B) being such that said silicone-modified water-based coating composition is storage-stable and forms a mat film which is soft to the touch.
Claim 2
Dependent Claim
19 words
The composition according to claim 1, wherein the average size of said silicone rubber particles is ≦ 200 micrometers.
Claim 3
Dependent Claim
62 words
The composition according to claim 2, wherein said water-based coating composition (A) is selected from the group consisting of water-based polyurethane resin coating compositions, water-based alkyd resin coating compositions, water-based aminoalkyd resin coating compositions, water-based epoxy resin coating compositions, water-based acrylic resin coating compositions, water-based silicone-modified epoxy resin coating compositions, water-based silicone-modified polyester resin coating compositions and water-based silicone resin coating compositions.
Claim 4
Dependent Claim
37 words
The composition according to claim 3, wherein 1 to 150 parts by weight of said particles of suspension (B) are used for each 100 parts by weight of the total solids in said water-based coating composition (A).
