| 摘要 | A stain resistant cover composition of the invention for a coloured rubber part of a tire comprises 100 parts by weight of water, 1.0 to 50 parts by weight of polyvinyl alcohol, 15 to 150 parts by weight (solid content) of a vinyl acetate resin emulsion, 0.5 to 5.0 parts by weight of a surfactant, and 0.5 to 5.0 parts by weight of a silicon oil. A stain resistant protective film of the present invention is used for a coloured portion in the side wall part of a tire, wherein the protective film comprises polyvinyl alcohol, a vinyl acetate resin emulsion, a surfactant, and a silicon oil. The present invention can provide a stain resistant cover composition for a coloured rubber part of a tire used for preventing the coloured part (side wall) of a tire from being stained by antioxidants bleeding from other tires, or dust, and from being scratched by contact with other tires when rubber tires are stacked while being transported or stored. | ||||||
