<p>PURPOSE:To correctly confirm service environments with the eye by laminating a magnetic recording layer, a heat sensitive recording layer and protective layer cured with ultraviolet rays on a supporter in that order. CONSTITUTION:This magnetic card is so constituted that a magnetic recording layer is placed on one surface of a supporter, a heat sensitive recording layer is placed thereon and a protective layer set by ultraviolet rays is placed thereon. The magnetic recording layer can be appropriately formed by a known method. Known substances can be employed as the color developing agent of the heat sensitive recording layer and the other materials. However, it is preferable that a specific application liquid is prepared so that the adhesion of the other materials to the magnetic recording layer is excellent and the cohesiveness of the heat sensitive recording material becomes powerful. As a binder, water soluble polyester is preferable. It is preferred that the ultraviolet curing protective layer be formed with solventless ultraviolet set resin.</p> |
