ABSTRACT:
The stain resistant cover composition of the present invention for colored rubber part of a tire is characterized by that it comprises water of 100 parts by weight, polyvinyl alcohol of 1.0 to 50 parts by weight, a vinyl acetate resin emulsion of 15 to 150 parts by weight (solid content), a surfactant of 0.5 to 5.0 parts by weight, and a silicon oil of 0.5 to 5.0 parts by weight. The stain resistant protective film of the present invention for colored rubber part of a tire is used as a stain resistant protective film for a colored portion in the side wall part of a tire, wherein the above 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 colored rubber part of a tire used for preventing the colored part (side wall) of a tire from being stained by antioxidants bleeding from other tires, or dust and being scratched by contact with tires when rubber tires are transported or stored as they are piled up, and a protective film therefor.
