(Meth)acrylate-functional organosilicon compounds M in which an oxygen atom connects the (meth)acrylate group to the silicon of the organosilicon compound, wherein the carbon atom bonded to the oxygen atom bears at least one further moiety bonded via carbon, with the proviso that in the presence of just one further moiety, said moiety contains more than one carbon atom, constructed of at least one unit of general formula I and at least one unit of general formula II R 2 b X c SiO [4-(b+c)]/2, R 1 a SiO (4-a)/2, where R 1 and R 2 are each independently hydrogen atoms or C 1 -C 20 hydrocarbon or C 1 -C 15 hydrocarbonoxy moieties in which one or more mutually nonadjacent methylene units may each be replaced by -O-, -CO-, -COO-,-OCO- or -OCOO or NR x groups and which are unsubstituted or substituted with substituents selected from -CN, N R x 2, COOH, COO R x, -halogen,-acryloyl, -methacryloyl, -epoxy, -OH and -CON R x 2, R x is hydrogen or a C 1 -C 10 hydrocarbon moiety unsubstituted or substituted with substituents selected from -CN and halogen, X is an oxygen-bonded moiety of general formula O-C(R 3 R 4)-R 5 -O-(C=O)-CR 6 =CH 2) R 3 and R 4 are each independently hydrogen or C 1 -C 20 hydrocarbon moieties in which one or more mutually nonadjacent methylene units may each be replaced by O-(C=O)-C R 6 =CH 2, -O-, -CO-, -COO-, -OCO- or -OCOO- or NR x groups, with the proviso that when R 3 is hydrogen, R 4 contains at least two carbon atoms, R 5 is a divalent C 1 -C 20 hydrocarbon moiety in which one or more mutually nonadjacent methylene units may each be replaced by -O-, -CO-, -COO-, -OCO- or-OCOO- or NR x groups, R 6 is hydrogen or unbranched, branched or cyclic saturated or unsaturated alkyl of 1 to 12 carbon atoms or aryl or aralkyl, wherein individual nonadjacent methylene units may be replaced by nitrogen atoms or oxygen atoms, a is 0, 1, 2 or 3, b is 0, 1 or 2, c is 1, 2 or 3, and b+c is 1, 2 or 3. R 1 and R 2 are each independently hydrogen atoms or C 1 -C 20 hydrocarbon or C 1 -C 15 hydrocarbonoxy moieties in which one or more mutually nonadjacent methylene units may each be replaced by -O-, -CO-, -COO-,-OCO- or -OCOO or NR x groups and which are unsubstituted or substituted with substituents selected from -CN, N R x 2, COOH, COO R x, -halogen,-acryloyl, -methacryloyl, -epoxy, -OH and -CON R x 2, R x is hydrogen or a C 1 -C 10 hydrocarbon moiety unsubstituted or substituted with substituents selected from -CN and halogen, X is an oxygen-bonded moiety of general formula O-C(R 3 R 4)-R 5 -O-(C=O)-CR 6 =CH 2) R 3 and R 4 are each independently hydrogen or C 1 -C 20 hydrocarbon moieties in which one or more mutually nonadjacent methylene units may each be replaced by O-(C=O)-C R 6 =CH 2, -O-, -CO-, -COO-, -OCO- or -OCOO- or NR x groups, with the proviso that when R 3 is hydrogen, R 4 contains at least two carbon atoms, R 5 is a divalent C 1 -C 20 hydrocarbon moiety in which one or more mutually nonadjacent methylene units may each be replaced by -O-, -CO-, -COO-, -OCO- or-OCOO- or NR x groups, R 6 is hydrogen or unbranched, branched or cyclic saturated or unsaturated alkyl of 1 to 12 carbon atoms or aryl or aralkyl, wherein individual nonadjacent methylene units may be replaced by nitrogen atoms or oxygen atoms, a is 0, 1, 2 or 3, b is 0, 1 or 2, c is 1, 2 or 3, and b+c is 1, 2 or 3.
