Radiation-curable coating compounds consisting of a plurality of components, and the use of same in release-coated substrates

A composition, comprising:

• (I) 1 to 90 wt %, based on the sum of all components of the composition, of one or more compounds consisting of the elements carbon, hydrogen and oxygen and having 2 to 6 ethylenically unsaturated, radically polymerizable groups and at least one oxyethylene group,
• (II) 10 to 99 wt %, based on the sum of all components of the composition, of one or more organo-modified silicones of formula (I),
• M1aM2bD1cD2d (I)
• wherein
• M1=[R13SiO1/2],
• M2=[R12R2SiO1/2],
• D1=[R12SiO2/2],
• D2=[R1R2SiO2/2],
• a=0 to 2,
• b=0 to 2, and a+b=2,
• c=50 to 490,
• d=0 to 15,
• the ratio of the sum (b+d) to the sum (c+d+2) is from 0.004 up to 0.1;
• the sum (c+d+2) is from 50 to 500,
• R1 denotes identical or different aliphatic hydrocarbons having 1 to 10 carbon atoms or aromatic hydrocarbons having 6 to 12 carbon atoms, and
• R2 denotes identical or different hydrocarbons which have 1 to 5 identical or different ester functions, the hydrocarbon being linear, cyclic, branched and/or aromatic, and the ester functions being selected from ethylenically unsaturated, radically polymerizable ester functions and from ester groups which are not radically polymerizable;
• (III) 0 to 70 wt %, based on the sum of all components of the composition, of one or more organomodified silicones having 4 to 40 silicon atoms, where 15% to 100% of the silicon atoms have ethylenically unsaturated, radically polymerizable groups.
