Abstract
An adhesive composition comprised of (A) a latex of 100 wt. parts of a carboxyl group-containing highly saturated nitrile-conjugated diene copolymer rubber, (B) 5-30 wt. parts of a resorcinol-formaldehyde resin, and (C) 2-10 wt. parts of an aromatic epoxy resin. A composite comprised of a nitrile group-containing highly saturated copolymer rubber and a fibrous material, which has been treated with the adhesive composition. This composite is useful for belts.

An adhesive composition comprising:
- (A) a latex of a carboxyl group-containing highly saturated nitrile-conjugated diene copolymer rubber having an iodine value not larger than 120,
- (B) 5 to 30 parts by weight, based on 100 parts by weight of the carboxyl group-containing highly saturated nitrile-conjugated diene copolymer rubber, of a resorcinol-formaldehyde resin, and
- (C) 2 to 10 parts by weight, based on 100 parts by weight of the carboxyl group-containing highly saturated nitrile-conjugated diene copolymer rubber, of an aromatic epoxy resin which is a condensation product of a polyphenol with epichlorohydrin.
