Radiation-curable compositions containing linear organopolysiloxanes bearing (meth)acryloxy groups and a photosensitizer are useful for release coatings particularly release coatings with enhanced adhesion to the substrate onto which they are coated, for example those used for adhesives such as pressure sensitive adhesive labels.

Radiation-curing compositions

The invention describes novel organosilicon compounds having fluorescent groups, containing units of the formula ##EQU1## where R is an identical or different, a monovalent, optionally substituted hydrocarbon radical having from 1 to 18 carbon atom(s) per radical, which may be interrupted by one or more oxygen atom(s),

Radiation-curing or heat-curing organosiloxane compositions containing

A novel process for preparing organosilicon compounds containing (meth)acxyloxy groups is described, in which alkoxylated alk-2-yne 1,4-di(meth)acrylates (1) of the formula ##STR1## where R.sup.2 is a hydrogen atom or a methyl radical,

Process for preparing organosilicon compounds containing (meth)acryloxy

Process for the preparation or organosilicon compounds carrying

Organosilicon compounds having Si-bonded hydrogen atoms are reacted with organic compounds having aliphatic multiple bonds in the presence of triazene oxide-transition metal complexes. The triazene oxide-transition metal complexes are activated by heating at temperatures of from 50.degree. C. to 250.degree. C. and/or by irradiation with light.
