POLYMERIC COMPOSITION, METHOD OF PRODUCING DIRECT PART MARKING WITH POLYMER COMPOSITION AND DIRECT PART MARKING Russian patent published in 2015 - IPC C09K11/02 C09K11/06 G03C1/73 B32B27/04 B32B27/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical polymer compositions for marking different objects, to polymer compositions for application directly on object to be marked of direct part marking (DPM) in particular to method of DPM with application of compositions, which contain fluorescent substances and/or particles (FDPM). In manufacturing marking device applied is fluorescent polymer composition, which absorbs light radiation at UV wavelengths, visible and/or close IR - ranges, irradiates in the range of wavelengths range ob band of passing of reading device input filter in the region of wavelength 400-700 nm and is solidified by drying and/or photo- and/or thermopolymerisation In production of marking device laser radiation is applied.

EFFECT: application of unified simplified technology for production and following decoding of FDPM on different surfaces, including those which possess properties, excluding application of FDPM on them by traditional, for instance, needle-shock method, in particular fragile, with high hardness, elastic, polluted, having coating with insufficient adhesion or covered with friable deposits, increased productivity of equipment and extension of spectrum of reachable FDPM parameters, such as reduced size, resistance to different impacts, applicability of additional protective procedures.
