Definitions

• the present invention relates to an image receptor used for image recording such as electrophotography or printer. Specifically, the present invention relates to an image receptor that is useful for image recording using a dye alone as an inking material.
• the dye In order to obtain a clear dye image, it is necessary for the dye to be molecularly and uniformly colored on the image receptor in order to obtain a clear dye image.
• an image receptor carrying a dye developer is usually used.
• An object of the present invention is to provide an image receptor which is used for image recording using a single dye as an ink and has a transparent coloring layer containing a color developer.
• the image receptor of the present invention has a structure in which a color-forming layer mainly composed of a screw is provided on a substrate], and the color-forming layer has an action of forming a single dye molecule in a molecular and uniform manner. It is.
• the figure is a schematic sectional view showing one embodiment of the image receptor of the present invention.
• a color forming layer 3 mainly composed of silica 2 is supported on a substrate 1 as shown in the figure.
• Silica 2 is used as a color developer and has excellent transparency. In addition, since it is colorless and has heat resistance, it does not cause yellowing due to heat, and a dye image with high color purity can be obtained.
• the use Ru silica force to the invention Example Eba 3: 1 ⁇ 3 20 ': 73102, 2. 0 3 ':. 73102, xMgO y S ⁇ 0 2 throat ⁇ . 3 ⁇ 4A silicate represented by y S iO or XH 00 0 A silicate represented by yS iO or amorphous silicon, glassy or colloidal silicon dioxide Applicable. Above all, a colloidal series having a pH of 6 or less is particularly excellent in that the dye is excellent in coloring property and the coloring layer is transparent.
• the substrate 1 can be applied to various types depending on the purpose of use.
• high-quality white paper art paper
• O PI O PI Is suitable.
• plastic sheets such as vinylon, cellophane and acetyl cellulose, which have excellent transparency and heat resistance, are suitable.
• a finely dispersed silica in a binder may be applied to the substrate 1 using a bar coater in a usual manner.
• the particle size of O. 1 following Mi-click opening down the Shi preferred.
• the binder has a strong binding force, is transparent, and is excellent in dispersion of the soldering force.
• a styrene-butadiene copolymer, ethylcell ⁇ -series, and an acrylic resin are preferred.
• a combination of a styrene-butadiene copolymer and a colloidal series is hardened by heating to improve heat resistance, and is particularly suitable for use in heating an image receptor.
• the amount of the binder to be added is preferably 30% by weight or less based on the silicon force.
• the coating amount of the coloring layer required to fully develop the dye, different but 1 ⁇ 1 o? ./ m 2 me by the dye used is appropriate.
• a dispersing agent may be added when dispersing the silicic acid into the binder.
• An antioxidant or quintia may be added to the coloring layer for the purpose of preventing fading of the dye.
• a well-known electron accepting substance such as an organic acid or an inorganic acid may be used in combination with silica as a color developing aid.
• the stomach down drill Roh Benzosu pyro Pila down), their respective Echiruseru opening - - 5 over Te door La methylation in the vinegar binder was applied to a thickness of 1 5 Mi-click and Russia down of capacitor paper, Three types of color sheets D, E, and F were prepared.
• the image receptor obtained in the example was superimposed on the color sheet, and the mixture was placed at 180 ° C. for 5 seconds for 1 second.
• a clear yellow and magenta colored image as shown in Table 1 was obtained on the image receptor. o
• the numbers in the table indicate the color densities.
• Table 2 shows the results obtained by superimposing the color sheet F on the colored image obtained by using the color sheet D in experiment 1 and heating it under the same conditions as in experiment 1. Such a bright red colored image was obtained.
• the color developing layer can be made transparent because a developer having excellent transparency is used. Therefore, the dye formed at the lower part of the color-forming layer is not concealed by the color developer at the upper part, thereby lowering the color-forming density. As a result, high-quality images can be realized using electrophotography or a printer.
