Beschreibung
Zusammenfassung:	This invention relates to a vulcanized rubber substrate such as, for example, a tire and a crosslinked, non-black rubber composition layer thereon such as, for example, a white sidewall. In one aspect, the invention relates to such a tire wherein said white sidewall is colored after its vulcanization with a contrasting colored dye. In another aspect, a dye solution is provided which is comprised of a dye dissolved in a hydrocarbon solvent which is characterized by having a solubility parameter of from about 12 to about 20 [J/m3]1/2.cndot.10-3 according to the Polymer Handbook. Upon application of such dye solution to, for example, a crosslinked white portion of a tire sidewall, such dye solution penetrates and swells at least a portion of said white tire sidewall. Upon evaporation of the solvent, a dyed penetration layer is formed.
