- JP S59-081369 A describes protective layers which can be prepared from coating compositions containing silicone-modified epoxy resins.
- a disadvantage of the epoxy resins described therein, however, is that conventional crosslinking agents such as phenol novolacs, melamine resins, phthalic anhydrides, amines or BF3 / amine complexes must be added.
- EP 0 263 237 A2 discloses silicone-modified epoxy resins obtained by reacting
- Double bonds containing epoxy resins with double bonds containing silicones can be prepared in the presence of a radical initiator.
- the resulting epoxy resins are exclusively thermoplastic coatings. Since only linear polydimethylsiloxanes are used, the resulting coating compositions are still thermally unstable due to their low degree of crosslinking.
- Coating compositions since they have the advantage of being able to be structured particularly simply by irradiation.
- EP 0 617 094 A1 discloses coating compositions comprising organopolysiloxanes having (meth) acrylic acid ester groups which, owing to the (meth) acrylate groups present, are present
- organopolysiloxanes are radiation curable.
- the described organopolysiloxanes are, however, due to insufficient chemical resistance, e.g. against etchants, disadvantageous.
- Epoxy groups with (meth) acrylic acid and monocarboxylic acids without double bonds can be produced.
- the polysiloxanes used can be prepared, for example, via addition of allyl epoxypropyl ether onto ⁇ , ⁇ -hydrogen dimethylpolysiloxane. Radiation curatives derived from corresponding polysiloxanes having epoxy groups attached via an Si-C bond
- etching agents are understood to mean substances which change the surface of the material to be etched in a chemical reaction, for example by oxidation, and thus bring it into solution.
- Etching agents can be acids, bases or oxidizing substances.
- EP 0 281 681 B1 likewise discloses radiation-curing polysiloxanes having (meth) acrylic acid ester groups bonded via SiC groups.
- these polysiloxanes also have the disadvantage, because of the attachment of the (meth) acrylate groups via SiC bonds, that they likewise do not have sufficient chemical resistance, e.g. towards etchants.
