The present invention relates to an anti-fading composition that protects the composition from fading and its coating.

た。I Problems to be Solved by the Prior Art and the Invention 1 Fluorescent and phosphorescent dyes and pigments are easily decomposed by the ultraviolet rays contained in sunlight, and for this reason they can only be used indoors. is limited. If used outdoors, the color will fade in a few days, making it impractical. Colored pigments and dyes generally have a tendency to fade due to ultraviolet rays, and among these, fluorescent and phosphorescent dyes and pigments have a particularly strong tendency to fade. For this reason, if fluorescent and phosphorescent dyes and pigments were made UV resistant and could be used outdoors,
Its product value increases significantly. Thus, there has been a long-awaited development of a means to simply and effectively impart UV resistance.

、顔料を含む基材中に直接混合添加する方法が知られて
いる。Conventionally, when fluorescent or phosphorescent dyes or pigments are used, a method to prevent fading while maintaining the color tone is to use transparent dyes containing organic ultraviolet absorbers such as benzophenone, salicylate, and substituted acrylonitrile. There is a known method of creating a UV-based paint and applying it directly to the object to prevent fading in a thick film, or directly mixing and adding these organic ultraviolet absorbers into a base material containing dyes and pigments. ing.

生じる。Now, regarding the method of directly mixing and adding an organic UV-shielding substance into a base material containing fluorescent or phosphorescent dyes or pigments, the above-mentioned organic UV absorbers themselves are easily degraded by UV rays. Because the structure changes, or it bleeds out from the base material and is easily lost, the concentration of the organic UV absorber in the base material decreases, and the protective function from UV rays decreases.
It will decline over time. Furthermore, since most of the absorption edges are on the low wavelength side of about 350 nm or less, the protection effect from ultraviolet rays is weak. Furthermore, organic ultraviolet absorbers generally have limited solubility in various substrates and solvents, and the amount added is limited to a small amount. For this reason, when directly blended with fluorescent or phosphorescent dyes or pigments, the concentration of organic ultraviolet absorbers is kept low, and as a result, ultraviolet rays incident from the base material reach quite deep inside, and the ultraviolet rays from the side closer to the surface This causes fading of fluorescent and phosphorescent dyes and pigments and deterioration of the substrate structure.

範囲等の特性に大きな問題がある。Next, when an organic UV absorber is blended into a transparent paint and applied to a substrate containing fluorescent or phosphorescent dyes or pigments, the solubility of the organic UV absorber in the paint binder is Therefore, in order to obtain the necessary and sufficient shielding ability, it is necessary to apply a thick coating with a dry film thickness of several tens of micrometers or more. For this reason, the coating method is limited to screen printing and spray coating methods that allow thick coating, and thin film high-speed printing techniques such as gravure printing and offset printing cannot be used, which poses major problems in terms of workability, cost, range of use, etc. .

料用退色防止塗料を提供することにある。Therefore, the technical problem of the present invention is to have a UV shielding ability over a wide range up to just before the visible light range, to have good visible light transmittance, excellent weather resistance, and to have sufficient UV shielding ability with a thin film. This makes it possible to use coating methods such as gravure printing and offset printing, and to produce an anti-fading composition that can be applied in large quantities at low cost, as well as a fluorescent or phosphorescent composition consisting of a transparent liquid in which fine metal oxide particles are dispersed. Our objective is to provide anti-fading paints for light dyes and pigments.

It was discovered that if it is prepared on a substrate containing dyes and pigments, fading can be prevented without impairing the color tone of the substrate, and it can be used outdoors. Based on this point of view, the present invention has been made. It is something.

好適である。[Means for Solving the Problems] The present invention provides an anti-fading structure in which a transparent film in which UV-shielding metal oxide fine particles are dispersed is formed on the surface of a base material containing fluorescent or phosphorescent dyes or pigments. This is an anti-fading coating for fluorescent or phosphorescent dyes and pigments, consisting of a transparent liquid in which fine particles of metal oxides and metal oxides are dispersed. The metal oxide is preferably zinc oxide.

ることを見出した。The present inventors focused on zinc oxide as an inorganic material that effectively blocks ultraviolet rays, and after preparing it into fine particles with a particle size of 0.1 μm or less, they made it into a binder containing 5 to 90% by weight of the solid content of the paint. On the other hand, a fluorescent or phosphorescent dye consisting of a transparent liquid in which fine particles of metal oxide are dispersed and an anti-fading composition that blocks ultraviolet rays up to near visible light and transmits visible light well by uniformly dispersing them. It was discovered that an anti-fading paint for pigments can be produced.

、高ヘイズになり、目的の退色防止構成体及び前記塗料
が得られない。However, if the particle size of the zinc oxide used is 0.1 μm or more, the surface area per unit weight will be small, resulting in low ultraviolet shielding ability, and high light scattering in the visible light range will result in high haze. However, the desired anti-fading composition and the paint cannot be obtained.

.. 1 μm or less, but preferably 90% of it is 0.0
Ultrafine particles within the particle size range of 0.05 to 0.05 μm are preferred.

る。Furthermore, if the amount of zinc oxide ultrafine particles added is less than 5% by weight based on the solid content of the paint, the UV shielding ability will be insufficient, and if it is more than 90% by weight, the proportion of the binder will be too small and the coating will have a sufficient degree of Since a film cannot be formed, the amount of zinc oxide ultrafine particles added must be 5 to 90% by weight based on the solid content of the paint. Furthermore, it is preferably 40 to 80% by weight.

性等に非常にすぐれたものである。Zinc oxide is used as the paint for forming the anti-fading transparent coating used in the present invention, because it has fluidity and the amount of binder needs to fill in the spaces between the ZnO particles to provide film strength. It is preferably 90% by weight or less in the solid content. Otherwise, the coating becomes extremely brittle. Furthermore, if the zinc oxide content is 5% by weight or less, the proportion of light that does not pass through the zinc oxide increases, which reduces the ultraviolet absorption efficiency, which is not preferable. The coating film produced using the coating film-forming material of the present invention has excellent ultraviolet blocking properties, and has excellent translucency, sanitary properties, weather resistance, and the like.

なる。On the other hand, the spectral transmission curve of the paint of Comparative Example 1 shows that the transparency is sufficient, but the UV shielding ability is not sufficient. In order to further enhance the ultraviolet shielding effect, the paint of Comparative Example 1 can be applied thicker, but in this case, in order to apply thicker,
It is not possible to select a coating method that is inexpensive and suitable for mass production, such as offset printing or gravure printing, and if a thick coating is applied using a screen printing method, etc., the coating cost will increase significantly, and organic ultraviolet absorbers are Most of them have a yellow to brown color due to their structure, and when the film thickness is increased or the concentration is increased, the color develops and the vividness of the color is lost, which is not compatible with the purpose of preventing fading using an overcoat.

In addition, the ultraviolet absorption edge is located on the shorter wavelength side compared to the paint for antifading coating film example 1, that is, the amount of ultraviolet light transmitted increases, which is disadvantageous in terms of antifading effect.

We conducted an outdoor exposure test for about 1 year and compared the results with non-exposed conditions every certain number of days.

I know it's not suitable. Further, Sample No. 3, which was overcoated with the paint of Comparative Example 1, has an effect when compared with Sample No. 1.4, but compared with Sample No. 2, the fading prevention effect is small and cannot be said to be sufficient. On the other hand, sample number 2
The fading was significantly improved compared to the uncoated one, and after one year of outdoor exposure, the dE of anti-fading paint Example 1/the dE of the uncoated one was 1/6 times that of yellow and 1/9 times that of orange. The color fading was suppressed to 115 to 1/9 times as much as red, showing a remarkable anti-fading effect.

考えられる。As mentioned above, the anti-fading paint Example 1, which contains particulate zinc oxide, has excellent transparency (see Figure 1), so it does not impair the color tone of the underlying fluorescent pigment at all. Therefore, it is considered to be optimal as a fading prevention coating for top coating.

90% by weight dispersed in a binder with a haze of 10 or less, the coating film is used as an ultraviolet shielding layer as an anti-fading composition for fluorescent and phosphorescent dyes and pigments, as well as metal oxide fine particles. This anti-fading paint for fluorescent or phosphorescent dyes and pigments is composed of a transparent liquid in which pigments are dispersed, and the following remarkable technical effects have been obtained.

しく容易になった。First, if it is applied to the surface of a base material containing fluorescent or phosphorescent dyes or pigments, which have traditionally been difficult to use outdoors because they are easily degraded by ultraviolet rays, even gravure printing, offset printing, etc. Even with a thin film that can normally be formed, for example, 5 μm or less, a coating film that sufficiently blocks ultraviolet rays over a wide range and at the same time transmits visible light well can be formed, so fluorescent, phosphorescent dyes, At the same time, the color tone of the pigments is not impaired, and at the same time, their fading is significantly suppressed, making it extremely easy to use fluorescent and phosphorescent dyes and pigments outdoors.
