The tread rubber constituent for the tire which contains the sublimation Characteristic dye which generates the smoke which is activated the tread rubber constituent for the color

摘要

PPROBLEM TO BE SOLVED: To provide a tread rubber composition for a tire, capable of giving smoke for producing a visual effect in a drifting event or for satisfying an exhibition idea of a sporty driver, by emitting the smoke of various colors, when friction is generated between the tire and a road surface, to provide the tire give by using tread rubber thereof, and to provide a method for producing the same. PSOLUTION: This tread rubber composition for the tire contains a sublimating dye which is activated by heat generated in case of the friction between the tire and the road surface and emits the smoke having the various colors within a wavelength range of about 39×10SP-6/SPto 76×10SP-6/SPcm and a frequency range of about 39.5×10SP-13/SPto 77×10SP-13/SPvps.
