Abstract: FIELD: magnetic indicator panes with inversion of material. SUBSTANCE: invention is related to magneto-inversion indicator panel with inversion of material in which image is formed by inversion of magnetic displaying material with the aid of magnet and is erased by inversion of material on same side. Technical result of invention consists in development of indicator panel with inversion of magnetic material characterized by increased definition of image and its erasure from panel on which image is formed by inversion of magnetic material. This technical result is achieved as magnetic indicator panel with inversion of material has base carrying liquid dispersion characterized by certain value of yield point and containing in the capacity of key components magnetic displaying material in the form of thin particles which magnetic poles of opposite signs are differently colored by deposition of thin metal layer on one surface as minimum and fabrication of second surface in color different from color of thin metal layer on first surface, dispersive medium and thickening agent. Summary area of S poles or surface of N poles of magnetic displaying material in the form of thin particles amounts to 60% as minimum of area of displaying surface of indicator panel, or is equal to it or exceeds given area by factor of 15 and not more. Due to this magnetic indicator panel with inversion of material corresponding to proposed approach demonstrates good contrast range and makes it feasible to form image of metallic or pastel hue. EFFECT: increased definition of image and its erasure from panel on which image is formed with inversion of material. 15 cl, 6 tbl
