摘要

2. Magnetic device and the process of producing optical effect layer (OEL), including non spherical pigment or magnetic powder particles guided by magnetic. In particular, magnetic assemblies and processes used to produce such sensitive nuclear materials are used as a means to combat counterfeiting of safety documents or safety or decorative items. 1. Requirement 1: a process for producing an optical effect layer (OEL) coating;The characteristics of a radiation curable coating composition composed of non spherical pigments or magnetic powder particles applied on a substrate surface, wherein the radiation curable coating composition is in the first state, （2） The radiation curable coating component is exposed to the magnetic field of a device, which includes: (a) a magnetic field assembly (x30) composed of a bracket matrix (X34) and (1) a magnetic field generating device with the shape ofMagnetic resonance (X31) is a single magnetic bipolar tube in the form of loop, whose magnetic axis is basically perpendicular to the surface of the substrate, or a combination of two or more magnetic bipolar tubes expressed in the form of loop in a regulation.Two or more magnets, dibolos, each have an axis substantially perpendicular to the surface of the substrate and have the same magnetic field direction, (A2) a single magnetic dipolo (X32), whose magnetic axis is substantially perpendicular to the surface of the substrate, or two or more magnetic dipolos (X32), whose magnetic axis is substantially perpendicular to the surface of the substrate, and has the same magnetic field direction and / or one or more polar components (x33),(b) A magnetic field generating device (X40) is a single row of magnetic rods, whose magnetic field axis is basically parallel to the base surface, or is composed of two or more bar magnetic rods (x41),Two or more types of magnetic rods (x41) each have a magnetic axis substantially parallel to the surface of the substrate, with the same magnetic field direction, and the purpose is to guide at least part of the non spherical pigment or magnetic mass spectrometer particles, （3） The composition of the curable coating is cured at least partially by radiation from step 2 (2) to step 2 (2), so as to fix the non spherical magnetic or magnetic pigment particles in its position and direction;The optical effect layer provides an optical impression of one or more annular objects, the size of which varies according to the inclination of the optical effect layer.
