Abstract
The invention pertains to mixtures or pastes comprising a cellulose ester, a binder resin, water, and optionally a plasticiser, an organic solvent, an emulsifier, and/or a thickener, wherein in that at least a portion of the binder resin is functionalized with an amino-functional acetal. The mixtures can be cured at ambient temperature. The mixtures or pastes can be used for, for example, varnishing wood, metal, synthetic material, paper, leather, glass, and plastic films, and in particular on surfaces where great value is placed on solventless coating compositions.
