Adhesive composition for textile/rubber adhesive bonding, and tire comprising a textile/rubber composite

Abstract

The present invention concerns an adhesive composition that can be used to bond textile fibers adhesively to a cross-linkable rubber composition, textile fibers sized by means of the said adhesive composition, a composite comprising the textile fibers and a cross-linked rubber composition that is permeable to light, and a tire body whose sidewalls comprise the composite. An adhesive composition according to the invention comprises an aqueous thermosetting phenolic adhesive containing at least one diene elastomer and at least one organic pigment. This adhesive composition is the reaction product the aqueous thermosetting phenolic adhesive and an aqueous pigmentary dispersion containing the organic pigment.
