Adhesive composition for bonding fibers to rubber

摘要

An adhesive composition for bonding fibers to a rubber is made of an aqueous dispersion composed mainly of a resorcinol/formaldehyde resin and a rubbery vinylpyridine copolymer latex. Particles of the rubbery vinylpyridine copolymer latex having a weight-average particle size of at least 0.15 micron, provided when the weight-average particle size is less than 0.16 micron, the particles having a particle size of at least 0.18 micron amount to at least 5% by weight.
