METHOD FOR PRODUCING MULTILAYER MICROPARTICLES

摘要

FIELD: microparticles for marking objects of any kind including animal and plant. SUBSTANCE: method includes following steps: substrate made in the form of rectilinear or curved strip is covered with several marking layers in succession; application of each marking layer is followed by drying and/or curing process to form multilayer stack of desired kind and desired sequence of marking layers prior to application of next layer; separation of substrate from multilayer stack; crushing of multilayer stack into multilayer particles without disturbing sequence of marking layers. In the process separate marking layers are applied by printing method. Each marking layer may be likewise applied by bronzing or varnishing, varnish being applied by spraying or with aid of roller. EFFECT: enlarged functional capabilities. 25 cl
