のをいう。Conventionally, in order to measure ultraviolet irradiation intensity, ultraviolet integrated illumination, etc., technologies such as photocurrent conversion and electrolysis have been used, which requires electrical operation and measurement, and as a result, the equipment has become extremely expensive. Ta. The present inventor has discovered that a specific composition changes its color when irradiated with near ultraviolet rays and increases the color density stoichiometrically, and provides a simple measuring tool using this composition as a near ultraviolet detection material. As a result of repeated research aimed at this purpose, we have arrived at the present invention. This application consists of two inventions; the first invention is a solution made of the above composition, and the second invention is a sheet-like product using the solution. In order to use the solution composition of the first invention as a detection material in a simple measurement tool, it can be placed in a shallow container made of quartz or the like with low ultraviolet absorption. The second invention of the present application is a product in which the solution composition described above is coated on a sheet, or the essential components of the first invention are laminated and coated on a sheet as a single product without mixing, and finished as a label or the like. The integrated illuminance of ultraviolet rays can be easily measured based on the color change and color density change. The specific composition referred to in the present invention is one which contains polyvinyl chloride with a low degree of polymerization and a specific colored dye or colorless dye as essential components and exhibits the above-mentioned effects. Also, laminated coating on a sheet as a single product means that the layers of the above-mentioned □-components are combined on a sheet.

定するのに適した材料の得られることが判った。``Problems to be Solved by the Invention'' It is known that polyvinyl chloride causes changes in color tone and color density due to physical energy such as heat, light, and shearing force. In particular, those with a low degree of polymerization and single polymers that are not copolymerized with vinyl acetate etc. are likely to cause the above color change. However, these color changes cannot be used as a sensing material. This is because the amount of change is too small. Therefore, we focused on free radicals and hydrogen chloride generated during the photodecomposition process of polyvinyl chloride. From the results of numerous experiments, it was discovered that there are colored dyes or colorless dyes that undergo stoichiometrically accurate color changes under the influence of trace amounts of hydrogen chloride or free radicals generated during the decomposition process, and that low polymerization with either of these dyes is possible. It has been found that a material suitable for measuring near-ultraviolet integrated illuminance can be obtained by coexisting with polyvinyl chloride.

することが好ましい。UV light sources that are generally used for various purposes include sunlight, carbon arc light, mercury lamp light, xenon lamp light, etc., but none of them include light with a wavelength of 200 OA or less, so the detection range is It is suitable for wavelengths of 200OA or more. In addition, 40001 or more is in the visible range, and since the storage conditions are disadvantageous in practice for substances that cause color changes and color density changes (hereinafter referred to as color changes) due to visible light, the present invention uses wavelengths in the range of 2000A to 4000A. The integrated illuminance can now be calculated using the irradiation light. As mentioned above, a single vinyl chloride polymer that is not copolymerized with low polymerization degree polyvinyl chloride, vinyl acetate, etc. has a wavelength of 2000.
When irradiated with near-ultraviolet light at ^~4000^, it photodecomposes to produce hydrogen chloride, albeit in a very small amount, and free radicals are generated during the decomposition process. However, in visible light, these can be ignored. Among these polyvinyl chlorides having a low degree of polymerization, those having an average degree of polymerization of 250 to 600 are preferably selected and used in the present invention.

て塗膜を形成したときの物性が悪いという欠点もある。If the average degree of polymerization is 600 or more, the stability of polyvinyl chloride increases and sensitivity is likely to deteriorate. If the average degree of polymerization is less than 250, the polymer itself may contain free hydrogen chloride, etc. This is because it is unsuitable as a raw material for. In addition, in the second invention of the present application, such polyvinyl chloride also has the disadvantage of poor physical properties when a composition or a single product thereof is applied to a sheet to form a coating film.
最も好ましいのは平均重合度３００〜４００の範囲であ

できる。Furthermore, colorless dyes that are colored only by irradiation with light having wavelengths other than zoooX to 400 d, particularly visible light, are not preferred. Preferred examples of colorless dyes that satisfy the above requirements include leuco dyes conventionally used in pressure-sensitive recording paper, heat-sensitive recording paper, etc., and the following can be used. Triphenylmethane phthalide series, fluorane series, 7 etchazine series,
These include indolyl phthalide series, leukoolamine series, spiropyran series, triphenylmethane series, triazene series, naphtolactam series, azomethine series, benzobylane series, spirophthalanxanthin series, hydroxyphthalamine series, and rhodamine lactam series. All of these are colorless, but after color development in the composition of the present invention, various colors are imparted depending on the colorless dye of each series, and the color density increases in accordance with the irradiation time. These may be used in combination if necessary.
In addition, when the composition is applied to a sheet, it is also possible to apply different colored compositions separately to the base area. The above-mentioned leuco dye is an electron-donating substance, and coloration occurs due to interaction with free radicals generated during the photodecomposition process of polyvinyl chloride or action with hydrogen chloride that remains as a result, and the color density is stoichiometrically Since the photochemical changes in polyvinyl chloride are accurately amplified, the integrated illuminance can be accurately detected. Since this type of dye is often oil-soluble, it is dissolved in an organic solvent together with polyvinyl chloride, and placed in a plastic container, quartz container, etc. that has low ultraviolet absorption, and is used as the detection material of the first invention of the present application. In that case, a low concentration solution is used and the change in concentration is determined by a densitometer and the integrated illuminance is calculated. According to the second invention of the present application, the visually detectable material may be a base material such as paper, film, glass plate,
A polyvinyl chloride solution of the same single component is coated on the surface of a metal plate, etc., which has previously been coated with a single colored dye or a colorless dye and dried. The order of coating does not matter. Most leuco dyes are oil-soluble, so they are allowed to coexist in an organic solvent solution of polyvinyl chloride, and water-soluble and alcohol-soluble dyes, such as the indicators exemplified as colored dyes, coexist in an emulsion solution of polyvinyl chloride. It is also a preferred embodiment of the present invention to coat the mixture on a base material and use it as a sensing material after drying. To obtain the integrated illuminance, the integrated illuminance is obtained by comparing the standard color tone and standard color dark skin surface prepared in advance for each light source.As explained in detail above, the present invention can be used to obtain the integrated illuminance when polychlorinated beer with a low degree of polymerization is used at a wavelength of 2 ooo The polyvinyl chloride is used as one component, and the other component, colored dye or colorless dye, is irradiated with near UV rays within a range where near-UV irradiation at 4000 Å causes virtually no color change and color density change. This amplifies the photochemical changes in polyvinyl chloride, causing noticeable color changes and color density changes, and based on this, the integrated illuminance can be determined. It is possible to accurately determine the integrated illuminance within the irradiation range where no color change is observed. If necessary, stabilizers for polyvinyl chloride, antioxidants, ultraviolet absorbers, sensitizers, etc. may be mixed and used within the range that does not impair the effects of the present invention.
