First claim
Opening claim text (preview).
What is claimed is: 1. A color sealant composition for a tire, comprising: to 100 wt. parts of raw rubber, 10 to 60 wt. parts of surface modified silica prepared by placing silica at 300 to 500° C. for 30 minutes to 3 hours, 0.05 to 5 wt. parts of pigment, 40 to 100 wt. parts of polybutene having a number average molecular weight of 1,000 to 1,500, 60 to 300 wt. parts of polybutene having a number average molecular weight of 2,000 to 3,000, and 5 to 15 wt. parts of peroxide, so as to have self-sealing performance. 2. The composition according to claim 1 , wherein the raw rubber is at least one selected from natural rubber and butyl rubber. 3. A tire comprising the color sealant composition for a tire according to claim 1 . 4. A tire comprising the color sealant composition for a tire according to claim 1 , wherein the composition is applied inside an inner liner of the tire.
