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.

1 . Tire body having sidewalls comprising a composite comprising a cross-linked visible light permeable rubber composition bonded to textile fibers, wherein the composite comprises an adhesive composition between the rubber composition and the textile fibers, the adhesive composition comprising an aqueous thermosetting phenolic adhesive containing at least one diene rubber composition and an organic pigment, the adhesive composition being a reaction product of the aqueous thermosetting phenolic adhesive and an aqueous pigmentary dispersion comprising the organic pigment. 
   
   
       2 . Tire body according to  claim 1  wherein the rubber composition comprises a blend of natural rubber and at least one other diene elastomer, the natural rubber being the major proportion of elastomers in the blend. 
   
   
       3 . Tire body according to  claim 1  for fitting on a two-wheeled vehicle. 
   
   
       4 . Tire body according to  claim 2  for fitting on a two-wheel vehicle.
