| 摘要 |
The invention relates to radiation polymerization-curable, aqueous, structurally viscose, volatile organic compounds of whole or, in essence, free powder dispersions containing, as a dispersed phase, solid and/or highly viscous particles (A), which are dimensionally stable under conditions of storage and use and which have a mean particle size z-Mean of 80 to 750 nm measured with photon correlation spectroscopy. Particles (A) contain at least one radically cross-linkable binder (A1) with a glass transition temperature ranging from-70 to +50°C, with a content of olefinically unsaturated double bonds of 2 to 10 equ./kg and with a content of acid groups of 0.05 to 15 equ./kg in a quantity of 50 to 100 % by weight with regard to (A). The invention also relates to methods for producing these dispersions and to the use thereof.
