O.Z. 0050/41620 Abstract of the Disclosure: Aqueous synthetic resin formulations essentially contain A) from 3 to 75% by weight of one or more synthetic resins which consist of a) from 50 to 99.85% by weight of one or more esters of .alpha.,.beta.-monoethylenically unsaturated carboxylic acids of 3 to 6 carbon atoms and alkanols of 1 to 18 carbon atoms or one or more vinyl esters of an aliphatic monocarboxylic acid of 2 to 8 carbon atoms or of a mixture of these monomers (monomer a), b) from 0.1 to 12% by weight of one or more .alpha.,.beta.- monoethylenically unsaturated mono- or dibasic acids of 3 to 8 carbon atoms, of anhydrides thereof or of a mixture of these monomers (mono- mer b), c) from 0.05 to 10% by weight of one or more mono- ethylenically unsaturated monomers of 2 to 24 carbon atoms which are not an acetophenone or benzophenone derivative and have one or more aldehyde or keto groups or a mixture of both groups (monomer c), d) from 0 to 10% by weight of one or more mono- ethylenically unsaturated acetophenone or benzo- phenone derivatives or a mixture of these mono- mers (monomer d) and e) from 0 to 35% by weight of one or more other copolymerizable monoethylenically unsaturated monomers (monomer e), in polymerized form, the percentages by weight of monomers a, b, c and e being chosen within the stated limits so that a synthetic resin consisting only of these monomers would have a glass transition temperature of from 40 to -50°C, B) one or more organic compounds having two or more hydrazide groups, C) from 0 to 10% by weight, based on the synthetic O.Z. 0050/41620 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, D) effective amounts of emulsifiers or protective colloids or of a mixture of these active ingredients, E) not less than 5% by weight of water and 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.
