Claim 0:
1. A method for applying at least one silicone layer by laser transfer printing, the method comprising the following steps:
(i) providing a laser source;
(ii) providing a printing-composition carrier beneath the laser source, the printing-composition carrier being transparent to laser radiation and being coated on the lower side with a crosslinkable silicone composition, and at least the surface of the crosslinkable silicone composition being charged to a potential phi_1;
(iii) providing a deposition carrier beneath the printing-composition carrier;
(iv) providing an electrode beneath the deposition carrier, the electrode being charged to a potential phi_3, where phi_1 and phi_3 have opposite polarities;
(v) irradiating the printing-composition carrier with laser beams, so that at least a part of the crosslinkable silicone composition is detached and is transferred to the deposition carrier; and
(vi) forming a silicone layer by completely or partly crosslinking the silicone composition transferred to the deposition carrier.
