[Prior Art] When light is irradiated on metal microparticles, it will produce a phenomenon of resonance absorption (Plass Absorption); the absorption phenomenon varies depending on the type and shape of the metal; for example, the spherical metal particles are dispersed in water to form a colloidal metal. When the absorption range is near 530 nm and the shape of the microparticles is 10 nm in the short axis, in addition to the absorption near the 53 0 nm due to the short axis of the strip, there is also a long wavelength due to the relationship between the long axes of the strips. Side absorption: The ratio of the short axis to the long axis can be adjusted to achieve the desired wavelength (eg ' SS.Changetal, Langmuir ' 1 9 9 9, 15.p701-709, although metal particles have been known before. Resonance absorption phenomenon will appear, but it is not clear that the coating composition using this phenomenon, that is, the coating composition; and it is not known to utilize the specific shape of the metal microparticles to absorb the specific wavelength of visible light and near-infrared light. The polymer film which is obtained by the method is disclosed in, for example, Japanese Laid-Open Patent Publication No. Hei 1 1-8 0647 and Japanese Patent Publication No. 11_3 1 9 5 3 8 The colloidal solution of colloidal particles of metal and copper and the high-scoring 1313702 (2) sub-pigment dispersant are described for the purpose of improving the coloring property of the coating and the stability of the solution, and not for obtaining the shape of the specific metal microparticles. The absorption effect of the near-infrared light, the electromagnetic wave shielding effect, and the Japanese Patent Publication No. 9-5062 No. 10, although there are also descriptions of the metal carbide nanoparticle and the method for producing the same, but the shortness of the specific metal microparticles The ratio of the axis to the long axis can improve the absorption function of near-infrared light, and it is completely unknown. There is no suggestion on the use of this as a coating material and on the optical material. Also, in order to form a metal wiring pattern, it is known. A resonance absorbing inorganic fine particle having a diameter of less than 10 〇 nm and a long axis/minor axis ratio of more than 1 is used, and is attached to a fine strip grown on a solid surface (described in JP-A-200-64794); The fine strips grow under the condition of being attached to a solid surface, but cannot be dispersed in various solvents and adhesive components, so that it is impossible to coat; and, metal particles The resonance absorption is only used for the purpose of growth in the synthesis process, and is not utilized to make screening absorption of specific wavelengths of visible light and near-infrared light by making the long axis of the nano-bar metal. On the other hand, 'Japan Special Open 2000 Japanese Patent Publication No. -28 8 1 3 discloses that a resin film obtained by dispersing metal fine particles is laminated to form a filter having an electromagnetic wave shielding function. The resin composition having a near-infrared light shielding function is laminated. In addition, Japanese Laid-Open Patent Publication No. 2000-56 1-27 discloses a filter for shielding electromagnetic waves and near-infrared light. However, the resin composition of the former having a near-infrared light shielding function is a polymer containing a monomer having an unsaturated double bond, a dish atom, and a copper atom; the latter is -9-

The amount of the nano-stripe metal added is suitably from 0.01 to 900 parts by weight of the adhesive component of 100 parts by weight; when the amount is less than the above range, it is difficult to obtain a desired effect; when the amount is more than the above range, Will increase the cost; in addition, due to the short axis of the strip metal, the inherent resonance absorption enhances the tendency to absorb the effect beyond the wavelength of the target -18-13321 (12); the dye is below 780 nm. a pigment having a screening absorption function in a wavelength range, and the amount thereof is preferably 0.01 to 900 parts by weight based on 100 parts by weight of the adhesive component; when the amount of addition is too small, it is difficult to obtain a sufficient complementary color effect, and when it is too large, it will be The cost increases; or the dye, or pigment, when the absorption is enhanced, it is difficult to obtain a colorless purpose; the nano-strand metal and the dye, or the pigment have almost the same wavelength range, or use different 2-3 or more kinds of nanometers. A combination of a strip metal and a dye or a pigment may be used; the amount of the nanowire metal added is preferably 0.01 to 900 parts by weight of the adhesive component, and is less than the above range. Difficult to sufficiently obtain the surface resistivity to obtain the desired, greater than the above range, the cost will increase.

The specific wavelength has the performance as a filter for a color filter and a filter for a near-infrared light. • It has a very low surface resistance and can be obtained as a filter for electromagnetic wave shielding. 16~17 respectively use dyes and pigments to have a complementary color effect on the wavelength of nanometer strips of gold at 530 nm, so that the transmittance of the visible light range is kept stable, and a colorless filter can be obtained; in Example 18, a dye and a naphthalene are added. Rice linear silver, which increases the complementary color effect of the dye, and obtains the conductive effect of the nanowire silver from the low surface resistance. On the other hand, Comparative Example 1 is a spherical colloidal gold, although it can absorb a wavelength of 530 nm, but its surface resistance is too high; Comparative Examples 2 and 3 use dyes and pigments, respectively, although they can absorb specific wavelengths, but with nano-stripe Compared with the metal phase, the absorption coefficient is too small. If the addition amount of the dye is increased, the cost is increased. Moreover, the dye and the pigment cannot impart conductivity, and the surface resistance is increased, and the shielding effect of the electromagnetic wave cannot be obtained. [Effects of the Invention] The light-absorbing refracting device of the present invention, as shown in Tables 1 to 3, has a screening absorption effect on a specific wavelength of visible light and near-infrared light, and because the surface resistance is very low, the wavelength is 400 nm. Visible light of 2000nm' Near-infrared light has a screening absorption function, and has electromagnetic wave shielding function 'can be used as a filter; then add dye, color, can increase the complementary color effect' can be made into a colorless filter Moreover, since the nano-bar metal and the nano-wire metal crucible use -25-1313702 (19), the surface resistance can be greatly reduced. -26-
