    Abstract: The invention concerns aqueous alkyl diketene dispersions containing a C14-C22 alkyl diketene and 1-10 wt.% polymer-type protective colloid, and characterised by the fact that they contain as a protective colloid (a) copolymers of (1) N-vinylpyrrolidone and (2) at least one quaternised N-vinyl imidazole or a substituted quaternised N-vinyl imidazole, in a molar ratio of 80:20 - 5:95 and integrated by polymerisation, and have a K value of at least 20 (using the method of H. Fikentscher in 0.5 m aqueous cooking salt solution at a polymer concentration of 0.1 wt.% and a temperature of 25 ~C); (b) condensation products obtained by (1) partial amidation of polyethylene imines with monocarboxylic acids and, optionally, (2) condensation of the partially amidated polyethylene imines with at least bifunctional cross-linking agents containing as a functional group a halo-hydrine, glycidyl, aziridine or isocyanate unit or halogen atom to produce cross-linked amidated polyethylene imines with a viscosity of at least 100 mPas in a 20 wt.% aqueous solution at 20 ~C; or mixtures of (a) and (b). The invention also concerns the use of aqueous alkyl diketene dispersions as glue in the production of paper, pulp and cardboard and for the water-repellant finishing of cellulose fibres.
