Adhesion of textile cords to rubber by dip coating using an N-methylol group containing polymer

An aqueous dispersion, useful as a coating composition for the adhesion of textile material to rubber, comprising (A) a rubber latex selected from styrene-butadiene latex containing up to 50% styrene, and polybutadiene latex;

• (B) a resorcinol-formaldehyde resin;
• and (C) from about 3 to about 15 parts by weight, based on 100 parts of dry rubber solids in said latex of a methylolated polymer of acrylamide having a molecular weight of at least about 10,000 and being from 60-100% methylolated.

A method for promoting the adhesion of a textile material to rubber, comprising (1) coating said textile material with a composition comprising (A) a rubber latex selected from natural rubber, polybutadiene rubber and styrene-butadiene rubber containing up to 50% styrene, (B) a resorcinolformaldehyde resin, and (C) from about 3 to 15 parts based on 100 parts of dry rubber solids in said latex, of a methylolated polymer of acrylamide having a molecular weight of at least about 10,000 and being from 60-100% methylolated (2) placing said treated textile material in intimate contact with a vulcanizable rubber composition to which said textile material is to be bonded;

• and (3) vulcanizing the composition at a suitable temperature.
