Zusammenfassung:The process for adhesively bonding together films, mouldings and fibrous or pulverulent materials made of plastics, paper, wood and metals with each or one another comprises using essentially protective colloid-free one-component systems based on a combination of an aqueous primary dispersion of a synthetic polymer and a water-insoluble polycondensate of phenols and aldehydes, which may be partly replaced by ketones. First the phenolic components of the polycondensate were mixed with an aqueous primary dispersion of a synthetic polymer. Then the polycondensation with the aldehydes, which may be partly replaced by ketones, was carried out in this mixture under customary conditions.
