    Abstract

    A method is for producing an ornamental design (O) in a clearcoat layer (K). The ornamental design (O) is produced by a selective matting of the clearcoat layer (K) by working the clearcoat layer (K) by a laser. The working of the clearcoat layer may be performed by a UV laser. Additionally, the working of the clearcoat layer K may be performed by electromagnetic waves at a wavelength of about 355 nm. Furthermore, the working of the clearcoat layer K may be performed by a laser operating at a frequency of about 23 500 Hz. Still further, the working of the clearcoat layer (K) may be performed by a laser operating with a pulse duration of about 2 s. The working of the clearcoat layer (K) may be performed by a laser operating with a line spacing of about 0.03 mm

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0015] FIG. 1 is a perspective view of a component having a clearcoat layer in which an ornamental design has been produced by the method of the invention.

    DETAILED DESCRIPTION

    [0016] The application relates to a method for producing an ornamental design O in a clearcoat layer K. The ornamental design O is produced by a selective matting of the clearcoat layer K by means of a working of the clearcoat layer K by a laser.

    [0017] The method according to the application allows a quicker working time to be achieved. There is no further preliminary work. Thus, the prior application of a film to the clearcoat layer is unnecessary.

    [0018] The working of the clearcoat layer K may be performed by a UV laser.

    [0019] The working of the clearcoat layer K may be performed by electromagnetic waves at a wavelength of about 355 nm.

    [0020] The working of the clearcoat layer K may be performed by a laser operating at a frequency of about 23 500 Hz.

    [0021] The working of the clearcoat layer K may be performed by a laser operating with a pulse duration of about 2 s.

    [0022] The working of the clearcoat layer K may be performed by a laser operating with a line spacing of about 0.03 mm.

    [0023] The application also relates to a component for a motor vehicle, in particular a body component for a motor vehicle, with a clearcoat layer K and an ornamental design O produced by the method described herein.

    [0024] The working of the clearcoat layer K may be performed by a laser of the Trumpf brand, in particular by means of the TruMark 3330 model. In this case, the laser may be operated at a power output of 65% with respect to the maximum output.

    [0025] The application also relates to a motor vehicle comprising a component as described herein.
