Abstract
The present invention relates to water-resistant aqueous dispersion adhesives with prolonged pot life and good color constancy of their bonds, comprising homopolymeric and/or copolymers polyvinyl esters, polymeric protective colloids, water-soluble compounds which can be complexed with the polymeric protective colloids, and derivatives of glyoxal and polyaldehydes having at least 3 carbon atoms, from which aldehyde groups can be controllably released in acidic media. The inventive dispersion adhesives are suitable for adhesively bonding porous and semiporous substrates.
