    • PURPOSE: To enhance stability in air of a dye precursor for black color forming recording and fastness of a dye formed therefrom against light, moisture or the like, by using a fluoran derivative having an arylamino group at 2-position, a long chain alkyl group at 3-position and an amine residue at 6-position.
      CONSTITUTION: A fluoran derivative having an arylamino group at 2-position of the fluoran ring, a long-chain alkyl group at 3-position and an amine residue at 6-position. A specified fluoran derivative having a long-chain alkyl group at 3- position of the fluoran ring is markedly water-insoluble and has a low melting point. Further, when an arylamino group, particularly, an anilino group, or a p- methyl or p-chloroanilino group is introduced to the 2-position of the fluoran ring, the fluoran derivative forms a color of pure black hue through interaction with a color developer having a phenolic hydroxyl group. Such a fluoran derivative is a colorless or light-colored crystal, is markedly hydrophobic, is highly soluble in organic solvents, and rapidly forms a black color upon contact with an electron-receptive substance. The developed dye is remarkably stable, and is excellent in fastness against discoloration or decoloration when being exposed to light, heat or moisture for a long period of time.

    • PURPOSE:To obtain a non-photo-sensitive picture recording material capable of giving recording at low voltage by a method in which an imagery electric current distribution is given to a picture recording layer containing a reducible metal compound, a reducing agent, and thioether, provided on a supporter, in such a way as to form a latent image, and the picture recording layer is heated to form a visible picture. CONSTITUTION:An electric current distribution in a sufficient amount to form a latent image is given by using a needle electrode 16 to the picture recording layer 10 of a picture recording material having at least a picture recording layer containing a reducible metal compound (e.g., silver laurate, etc.), a reducing agent (e.g., p-phenyl phenol, etc.) to reduce the metal compound, and a compound of the formula (where R is an alkyl or aryl, R and R are each H, an alkyl, or aryl, Z is OH, carboxyl, or carbamoyl, and k is an integer of 1-8). The picture recording layer 10 is heated on a heating platen 20 to form a visible picture corresponding to the latent image.
    • 目的：为了获得能够通过对包含可还原金属化合物，还原剂和硫醚的图像记录层给出图像电流分布的方法在低电压下进行记录的非感光图像记录材料， 设置在支撑体上，以形成潜像的方式，并且图像记录层被加热以形成可见图像。 构成：通过使用针状电极16向具有至少包含可还原金属化合物的图像记录层（例如，银）的图像记录材料的图像记录层10给出足够量的电流分布，以形成潜像 月桂酸酯等），还原剂（例如对苯基苯酚等）以还原金属化合物，和下式化合物（其中R 1是烷基或芳基，R 2和R 3为H，烷基或芳基，Z为OH，羧基或氨基甲酰基，k为1-8的整数。 图像记录层10在加热台板20上加热，形成与潜像对应的可视图像。

    • PURPOSE:To provide a recording medium capable of being easily produed from inexpensive materials and capable of developing acolor in sufficient density with low energy, wherein a layer of a metal capable of librating electrons through oxidation such as Al, a color former capable of forming a color through recution and a metallic compound are combined with each other. CONSTITUTION:A base 1 (e.g., a paper, a plastic film, a metallic foil) is provided at least on a surface thereof with a conductive layer 2 comprising a metal (e.g., Mg, Al) capable of librating electrons when being oxidized by impressing a voltage thereon. A conductive binder layer 3 incorporating a color material capable of forming a color or being discolored when being reduced by impressing a voltage thereon [e.g., a tetrasolium salt of the formula (wherein R is phenyl, alkyl; R' is H, alkyl, phenyl, COOC2H5 or the like)] and a metallic compound (e.g., an oxide of Zn, Ti or the like, a sulfide of Cd or the like) is provided on the surface of the base 3 to obtain the recording medium. EFFECT:Recording is accomplished by impressing a low voltage of not higher than 10V.
    • 目的：提供能够容易地从便宜的材料生产并且能够以低能量以足够的密度显色的记录介质，其中能够通过氧化的电子如Al的能够形成电子的金属层，能够形成 颜色通过重新排列和金属化合物彼此组合。 构成：至少在其表面上至少在其表面上提供基底1（例如，纸，塑料膜，金属箔），导电层2包括当被氧化时能够起电子的金属（例如，Mg，Al） 在其上施加电压。 导电粘合剂层3，其通过在其上施加电压而被还原以形成颜色或变色的着色材料[例如，式（其中R是苯基，烷基; R'是H，烷基，苯基 ，COOC2H5等）]和金属化合物（例如，Zn，Ti等的氧化物，Cd等的硫化物）设置在基材3的表面上以获得记录介质。 效果：通过施加不高于10V的低电压来实现记录。
