Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims:

1. A radiation-curable coating material comprising at least one radiation-curable binder having at least two acrylic ester and/or methacrylic ester groups, which comprises
(a) as binder (a) a mixture of
(al) at least one binder (al) having at least two acrylic
ester and/or methacrylic ester groups and having an elongation at break of at least 20* and
(a2) at least one further binder (a2) which is different
from (al) and has at least two acrylic ester and/or methacrylic ester groups,
(bl) at least one silicone-containing lubricant and
(b2) at least one halogen-containing polyolefin wax.

2. The coating material as claimed in claim 1, which comprises as component (al) at least one binder having an elongation at break of at least 40*.

3. The coating material as claimed in claim 1 or 2, which comprises
(al) from 2.5 to 80* by weight, preferably from 10 to 50* by weight, of at least one binder (al) and
(a2) from 19.8 to 97.3* by weight, preferably from 25 to 89.8* by weight, of at least one binder (a2),
the percentages by weight being based on the overall weight of the coating material .

4. The coating material as claimed in one of claims 1 to 3, which comprises at least one further, organic lubricant which is different from components (bl) and (b2).

5. The coating material as claimed in one of claims 1 to 4, which comprises
(bl) from 0.1 to 3* by weight, preferably from 0.2 to 2* by weight, based on the overall weight of the coating material, of at least one silicone-containing lubricant (bl) and
(b2) from 0.1 to 5* by weight, preferably from 0.2 to 3* by weight, based on the overall weight of the coating material, and at least one halogen-containing polyolefin wax (b2).

6. The coating material as claimed in one of claims 1 to 5, which comprises up to 5* by weight, preferably from 0.5 to 2.5* by weight, based on the overall weight of the coating material, of at least one silane (c), preferably at least one silane having ethylenically unsaturated groups.

7. The coating material as claimed in one of claims 1 to 6, which comprises at least one silane selected from CH2=C(CH3)-C00-(CH2)3-Si(0CH3)3, CH2=CH-Si(OCH3)3,
CH2=CH-Si(0C2H5)3, and/or CH2=CH-Si(0C2H4-0CH3)3.

8. The use of the coating material as claimed in one of claims 1 to 7 for producing a multicoat paint system, especially as a clearcoat or as a topcoat.

9. The use of the coating material as claimed in one of claims 1 to 7 for coating metal substrates.

10. The use of the coating material as claimed in one of claims 1 to 7 for coating packaging containers, especially glass containers and/or metal containers, preferably two- or three-piece cans.
