Abstract
A laser-writable molding material containing A) at least one polymer material or at least one precursor compound which can be polymerised to give a polymer material, and B) a particulate salt-like compound or a mixture of particulate salt-like compounds, which under the influence of laser light changes its color or leads to a color change in the component A). In order to enlarge the range of matrix materials hitherto available for laser writing and to overcome the disadvantages of the previously used writing procedures for such matrix materials, the laser-writable molding material according to the invention is characterised in that the at least one polymer material of the component A) is selected from polymer compounds having siloxane crosslinking units.
