ABSTRACT:
The use of a small amount of a polyhydroxy containing anthraquinone compound in a rubber ply or skim stock greatly improves the humid aged adhesion of the rubber stock to brass plated steel cords or fabric. This invention is particularly useful in tires with steel cords or belts. The following formula describes the anthraquinone compound: ##STR1## where two of the R's are hydroxyl radicals and the remaining R's are selected from the group consisting of --H, --OH, --CH.sub.3, --NO.sub.2, --CH.sub.2 OH and --COOH, at least four of the remaining R's being --H.
