Abstract

Aqueous synthetic resin formulations containing PA0 A) from 3 to 75% by weight of one or more synthetic resins, PA0 B) one or more organic compounds having two or more hydrazide groups, PA0 C) from 0 to 10% by weight, based on the synthetic resin A, of benzophenone or acetophenone or of one or more acetophenone or benzophenone derivatives which are not monoethylenically unsaturated or of a mixture of these active ingredients, PA0 D) effective amounts of emulsifiers or protective colloids or of a mixture of these active ingredients, PA0 E) not less than 5% by weight of water and PA0 F) from 0 to 85% by weight of finely divided fillers, with the proviso that the total amount of the monomers d polymerized in the one or more synthetic resins A and of component C is from 0.05 to 10% by weight, based on the one or more synthetic resins A, and the ratio of the number of moles of hydrazide groups of component B and the number of moles of the aldehyde and keto groups of the monomers c polymerized in the one or more synthetic resins A is from 0.01 to 2. These synthetic resin formulations are suitable for coating, adhesive bonding, sealing or impregnating.
