いた。The present inventors have proposed that the photochromic fabric
Considering that it is used mainly in an atmosphere that is exposed to sunlight (ultraviolet rays) for a long time, the user enjoys the reversible color change function as a photochromic function,
It was considered that how hard it is for the user to be affected by ultraviolet rays is extremely important in practical use and in terms of commercial value. Because the ozone layer destruction on a global scale has recently been regarded as a problem, and at the same time, there is increasing concern and concern about the onset of skin cancer caused by repeated exposure to strong ultraviolet rays, and functionalities with ultraviolet shielding properties This is because products are required. However, in the technical field of the present invention, if a photochromic agent and an ultraviolet absorber are used in combination in order to provide an ultraviolet shielding property, the ultraviolet absorber exerts an ultraviolet light blocking effect, and the reversible color of the photochromic agent at the center is important. Since a contradictory problem such as inhibiting the development of the changing function occurs, it has been difficult to provide a function relating to the ultraviolet shielding property in the conventional photochromic cloth.

Drying temperature is preferably low, 160 ° C
The above-mentioned high temperature is not preferable except for processing in a short time since the decomposition of the dye starts. 100 to 15 from the point of productivity
0 ° C. is appropriate, and heat drying for about 1 to 3 minutes is preferable.
Further, it is preferable to carry out light water washing or hot water washing in order to remove the unfixed composition. If the fixing amount of the composition is less than 2% by mass, the photochromic function becomes difficult to visually recognize, and it is difficult to achieve an ultraviolet transmittance of 15% or less. On the other hand, if the content exceeds 35% by mass, not only is the padding process difficult due to an increase in the liquid viscosity of the treatment liquid, but the texture of the cloth becomes coarse and hard, and the cost increases, which is not preferable. More preferably, 10
-20% by mass. The fabric in the present invention may be a woven fabric, a knitted fabric, a nonwoven fabric obtained by a known device or apparatus, or a fabric obtained by a combination thereof, and is not particularly limited. UV transmittance at a wavelength of 280 to 400 mμ is 1
It should be less than 5%, more preferably less than 10%. Further, the air permeability is 5c.
m 3 / cm 2 · sec or more, and in order to obtain a cloth having such air permeability, the fineness of the fibers used,
The basis weight, density, structure and the like may be appropriately selected by known means. Naturally, as the air permeability is less than 5 cm 3 / cm 2 · sec, that is, the void portion of the fabric is smaller, the ultraviolet ray shielding rate is improved. In consideration of this, if there is not a certain degree of air permeability, it may not be practical for some applications.

考えられる。The photochromic dye-containing resin fine powder is
A resin fine powder having an average particle diameter of about 3 to 15 μ in which a spironaphthoxazine selenol compound is mixed as a dye at a ratio of 0.05 to 4% by mass into spherical resin particles mainly composed of a polymer of a hydrophobic vinyl monomer. Is preferred. When the spironaphthoxazine-based selenol compound is less than 0.05% by mass as a dye, it is difficult to exhibit a photochromic function, and when it exceeds 4% by mass, it becomes uneconomical. Acrylic monomers and styrene monomers are suitable as the hydrophobic vinyl monomer. The average particle size is preferably about 3 to 15 μm from the viewpoint of the dispersibility of the composition in the aqueous treatment liquid in the padding method, and is important in promoting uniform fixation to the fabric surface and uniform color development. Yes, it is preferable from the viewpoint of the expression of the ultraviolet shielding function. As such a fine resin powder containing a photochromic dye, for example, a photochromic water-based ink “Sunny Color” of Recording Materials Research Institute is applied. The aqueous photochromic ink is originally a photochromic dye having excellent light fastness and discoloration properties.In the present invention, however, it has been found that, upon its use, it can also exhibit an extraordinary effect such as ultraviolet shielding properties. It is up to the present invention to utilize the expression. By mixing such a photochromic dye-containing resin fine powder into a binder resin, and impregnating the cloth material in an aqueous treatment solution with an ultraviolet stabilizer, continuously treating by padding, and heat drying, the photochromic dye is obtained. It is considered that the contained resin fine powder is uniformly fixed to the cloth, and an ultraviolet shielding function, which is a different effect, is imparted to the conventionally known photochromic function.

Many derivatives of piperidine-based compounds such as 6-tetramethylpiperidinyl) sebacate have been synthesized, and are characterized in that they do not involve the absorption of ultraviolet light such as ultraviolet absorbers. Its function is mainly to improve light fastness. Hindered amine UV stabilizers
Although a commercially available agent may be used, for example, Tinofast RSC manufactured by Ciba Specialty Chemicals is suitable. Depending on the intended use, a small amount of an ultraviolet absorber or an antioxidant is preferably used in combination with a small amount of an ultraviolet absorber or an antioxidant to improve the light fastness, as long as the expression of the photochromic function is not impaired. An additive such as a softener may be added.
