发明名称 RECORDING METHOD AND RECORDING PAPER USED IN SAID METHOD
摘要 PURPOSE:To enable to easily obtain a negative record in which the ground is dark colored and a recording part has a relatively lighter color as compared with the ground color, by providing a recording layer comprising a colored substance being in a color- developed state and showing a low-lightness color and a decoloring substance functioning to decolor the colored substance by reacting therewith, on a base for a recording paper. CONSTITUTION:The recording layer 3 comprises the colored substance 5 and the decoloring substance 6, each of which is provided in a single layer in the state of being fixed through an appropriate binder or partition substance so that the substances 5, 6 do not react with each other at normal temperature. A leuco dye used for an ordinary thermal recording paper is used as the colored substance 5 is the color- developed state. The recording layer 3 may be constituted of the first layer 3 comprising the decoloring substance 6 and the second layer 3b comprising the colored substance 5. When an appropriate quantity of heat is given to the recording paper 1 through a known thermal head, the substances 5, 6 at the heated part are melted. Then, the substances 5, 6 thus melted react with each other to eliminate or lighten the color at that part, resulting in a record 4 having a relatively higher lightness as compared with that of the ground color.
