Document Type and Number:
WIPO Patent Application WO/2014/111440
Kind Code:
A3
Abstract:
The invention relates to an aqueous adhesive composition which comprises an unsaturated elastomer latex and a phenol-aldehyde resin consisting of at least: an aromatic polyaldehyde having at least two aldehyde functions, including at least one aromatic ring; a polyphenol comprising at least one aromatic ring: in the event of a single aromatic ring, the latter has two or three hydroxyl functions in meta position relative to one another or relative to each other. The rest of the ring is non-substituted. In the event of a plurality of aromatic rings, at least two of same each have two or three hydroxyl functions in meta position relative to one another or relative to each other. The two ortho positions of at least one of said hydroxyl functions are non-substituted. The weight ratio of polyphenol to polyaldehyde is no lower than 3.0.
