Improved water-dispersible allyl urethanes are obtainable by reaction of a polyglycol mixture with a hydroxyallyl compound and an isocyanate containing at least two NCO groups, the allyl urethane being nonionic.

Water-dispersible allyl urethanes and their use for the production of

Improved nitrocellulose mixtures contain a polyol as the desensitizing agent, the polyol being a solvent for nitrocellulose, soluble in water to a maximum of 10% at 20.degree. C. and non-volatile.

Desensitized nitrocellulose mixtures

Improved cellulose ester-polymer combinations contain a cellulose ester A and at least one polymerized monomer B of the following formula ##STR1## wherein the substituents have the meaning given in the description and wherein the particles of the combinations are essentially 0.1 to 10 mm in size.

Cellulose ester/polymer combinations, and their preparation and use

Improved cellulose ester dispersions in the aqueous phase contain dispersed particles which contain cellulose esters, a polymerized monomer A having a polymerizable double bond and a polymerized monomer B having at least two polymerizable double bonds.

Aqueous cellulose ester dispersions and their preparation

Water soluble, polymerizable binders suitable for surface coating contain co-condensed residues of at least two polyalkylene glycols with different molecular weights, an alkoxylated polyol, a polycarboxylic acid and an optionally substituted acrylic acid.
