ABSTRACT OF THE DISCLOSUREAn epoxy resin-diammonium salt emulsion is based on aliquid epoxy resin, water, an emulsifier and a latentcuring agent, wherin the emulsifier is(a) a polyvinyl alcohol obtained by saponification ofpolyvinyl acetate with a degree of hydrolysis of at least70% and a molecular weight of at least 5,000,(b) a polyoxazoline having a molecular weight of10,000-100,000, and/or(c) a copolymer of N-vinylpyrrolidone with- vinyl esters of mono- or dibasic carboxylicacids of up to 6 carbon atoms,- (meth)acrylic esters of mono- and dihydricalcohols of up to 6 carbon atoms,- maleic, fumaric, crotonic acid and/or- styreneand wherein the latent curing agent is the salt from a(a) diamine of the formulaH2N-CH2-R-NH2 or H2N-R-CH2-R-NH2wherein R is- an optionally substituted C4-9-alkyleneresidue,- an optionally substituted C6-9-cyclo- alkyleneresidue, or- a C7-9-aralkylene residue,with(b) optionally hydroxy-group-containing, aliphatic,cycloaliphatic, or aromatic mono- or dicarboxylic acids ofup to 12 carbon atoms.
