Definitions
- the present invention relates to a developed color sheet having a novel structure for a pressure-sensitive recording material.
- the photosensitive recording material is usually brought into contact with a color-developing sheet having an electron-donating silicone dye on its surface and a color-developing sheet having an electron-accepting color developer on its surface so that both surfaces come into contact with each other.
- This is a recording materials department that applies a color development reaction based on electron transfer by adding an image.
- the developer is one of the main components of the recording material of the present invention, and there have been various proposals.
- activated clay obtained by treating natural clay minerals with moderate or moderate acidity, or a phenolic compound or a nopol-type phenolic resin, Further, metal salts of aromatic carboxylic acids and the like can be mentioned.
- activated clay is the oldest color developer, but some cases have been replaced by subsequent organic color developers due to insufficient color development ability. ⁇
- the hydroxide is formed so that the hydroxide is neutralized with calcium or acid, and magnesium, Z, or magnesium is added to the acid-treated clay mineral.
- a developer for a pressure-sensitive recording material produced by introducing a lubricating agent component and drying it as desired (referred to herein as "semi-synthetic solid acid"). ), Improving the color performance of the electron-donating roico dye, maintaining the color-forming effect under high humidity, and improving the color-forming degree. This is the result of less time decay, etc.
- a new type of developer that can compensate for the weakness of conventional activated clay as an inorganic developer.
- the color developing ability can be expected to be as good or inferior to that of the organic color developer.
- the present inventors evaluated the suitability of the thus-produced new semi-organic developer "semi-synthetic solid acid" in the pressure-sensitive recording developer by various tests. As can be seen, it is clear that remarkable improvement of the color developing ability and ⁇ J ⁇ of the color image density under high humidity were recognized, and a clear difference from the conventionally known and officially used clay mineral based developers. Was observed, ⁇ On the other hand, as a drawback, it has been found that the robustness of a color image developed in a color developing layer using such a “semi-synthetic solid acid” as a coloring agent, for example, light resistance, is rather reduced. did. Disclosure of the invention
- various phenolic compounds used in combination with the "semi-synthetic solid acid" are not limited to low-molecular-weight phenolic compounds and phenolic resins.
- a particularly preferred phenolic compound which does not have side effects such as discoloration, coloring, and deterioration of a white background is, for example, quinolone (or quinolene). ⁇ ⁇ ⁇ ⁇ ----- 0 Dro xy Pen Zo * Ate, Nora-Hydroxy Pen Li-to
- the semi-synthetic solid acid used in the present invention is derived from a clay it having a layer structure composed of silica tetrahedrons,
- the content is contained in the ratio of
- the sum of magnesium and aluminum in the above ratio is only one of magnesium or aluminum.
- the atomic ratio of the total amount of either one is shown.
- the combined use of the “semi-synthetic solid acid” and the phenolic compound and the zinc compound makes it possible to reduce the possibility of using the “semi-synthetic solid acid” alone. It was found that the color image fastness was improved. However, as will be shown later in the examples, both the phenolic compound and the zinc compound are added to the "semi-synthetic solid acid" more than when both are added alone. At the same time, a very remarkable effect, especially the effect of improving the robustness of the color image, can be seen. That is, a synergistic effect is recognized. ⁇
- "semi-synthetic solid acid” is one of zinc compounds. or two or more, one or more phenolic compounds, binders, dispersants and other additives, and, if desired, clays, kaolins, Satin white, calcium carbonate, titanium white, magnesium oxide, magnesium, titanium oxide, lumina, lumina, hydroxylaluminum, Urea resin pigments; Mixing pigments such as plastic gum to form a coating liquid, paper, plastic film, plastic laminate paper, etc.
- air knife, blade "* blade, low nose, flex:,,,,, rabbit, commutation, cartridge The coating and drying are performed using various coating methods to form a color developing layer for recording ⁇ .
- a "semi-synthetic solid acid” is used as a color developer, and a zinc compound and a phenol compound are used together to form a color development layer.
- the color development speed, color density, and the robustness of the color image (light resistance, water resistance, moisture resistance, plasticizer resistance, oxidation gas resistance, etc.) and non-image areas (white background)
- the stability (persistence of coloring ability, resistance to yellowing), etc.
- Doo Ri So towards the top of the color density, the duration of the color density under high humidity, improvement of the pair ⁇ 0 ⁇ fastness of color color image and the light fading light down, and this white background does not yellowing, is worthy of special mention .

- Semi-synthetic solid acid (trade name: Silton SS-1) manufactured by Mizusawa Chemical Industry Co., Ltd. 100 parts, zinc oxide 10 parts, and the above-mentioned wet-ground pentanol-hydrogen 50 parts of a loquat-benzate dispersion was dispersed in 200 parts of water in which 1 part of sodium pyrophosphate was dissolved, and 50 parts of an aqueous solution of 10% starch oxide was added thereto. 48% SBR-Latex 50 parts' was added as a coating liquid to make a coating solution. This coating solution was applied to a 4 QZ m 2 base paper so as to have a dry coating amount of 4.5 ⁇ Z m 2 and developed (CF) sheet (sample code D).
