solids fraction between 30% and 100% by weight,
double-bond density between 1 eq/kg and 4 eq/kg (at a solids fraction of 100%), and
NCO content between 4% and 7% by weight,
to the substrate.
2. The method according to claim 1 , wherein the substrate is a substrate made of plastic, metal or wood.
3. A method of applying a surface-coating material to a substrate comprising:
areally contacting the layer of surface-coating material of a laminate with a carrier and at least one layer of surface-coating material comprising a double-bond-containing, OH-functional component A and a double-bond-containing, NCO-functional component 13 , having the following properties:
Component A
solids fraction between 30% and 100% by weight,
double-bond density between 2 eq/kg and 5 eq/kg (at a solids fraction of 100%), and

double-bond density between 1 eq/kg and 4 eq/kg (at a solids fraction of 100%), and
NCO content between 4% and 7% by weight,
applied to the carrier, with a surface of the substrate, and
removing the carrier from the layer of surface-coating material.
4. The method of claim 1 , wherein, prior to contacting the layer of surface-coating material with the substrate, a layer of adhesive is applied to the substrate.
5. The method of claim 3 , wherein the layer of surface-coating material is cured before and/or after application.
6. The method of claim 5 , wherein the surface-coating material is cured thermally and by radiation.
7. A method of applying a surface-coating material to a substrate comprising:
applying a layer of adhesive to the substrate,
applying, on the carrier side, a laminate with a carrier and at least one layer of surface-coating material comprising a double-bond-containing, OH-functional component A and a double-bond-containing, NCO-functional component B, having the following properties:
Component A
solids fraction between 30% and 100% by weight,
double-bond density between 2 eq/kg and 5 eq/kg (at a solids fraction of 100%), and

double-bond density between 1 eq/kg and 4 eq/kg (at a solids fraction of 100%), and
NCO content between 4% and 7% by weight,
to the substrate,
and
where necessary, removing a protective layer.
