Coated films

1. a process for the production of a coated substrate, the process comprising the steps of

1) applying a to a substrate surface coating composition comprising

A) one or more compounds containing at least one chemical function a) suitable for polyaddition with component B), said one or more compounds of component A optionally containing ethylenically unsaturated double bonds;

and

B) one or more compounds containing at least one chemical function b) suitable for polyaddition with component A) and which is different from chemical function a), said one or more compounds of component B) optionally containing ethylenically unsaturated double bonds, wherein at least one of components A and B must contain ethylenically unsaturated double bonds;

and optionally

C) ethylenically unsaturated compounds which do not contain isocyanate groups and isocyanate reactive groups,

D) photoinitiators,

E) additives comprising stabilizers, catalysts and other auxiliary substances

F) non-functional polymers and/or fillers,

2) curing the product of step 1) by initiating a thermal polyaddition reaction,

3) bringing the product of step 2) into the desired final form by thermal forming;

4) curing the product of step 3) by irradiation with actinic radiation.

2. The process of claim 1 , wherein none of the components capable of crosslinking by a polyaddition reaction has a mean functionality greater than 2.8.
