Abstract

PURPOSE: To obtain the magnetic sheet which is capable of applying printing which may be observed by naked eyes by uniting multiple small chambers sealed with magnetic material and liquid form material to sheet form.
CONSTITUTION: Fluid (liquid form material) 2 such as paraffin oil, silicone oil, etc. and needle- or flake-form magnetic material 3 are sealed in microcapsules (small chambers) 1 composed of epoxy resins, gelatine, etc. and a multiplicity of these microcapsules 1 are united to sheet form by binders 4 to provide the magnetic sheet. The abovementioned magnetic sheet prints and records visualized characters, symbols, etc. by forming the same by using the capsules 1, fluid 2, binders 4 having nearly the same refractive indices, and orienting the magnetic material 3 of the desired positions in dot form by using magnets 5, 6 thereby making said portions transparent.
