However, the flexibility of the glass material is poor, the durability is poor, and the impact resistance and light weight are not good. . Therefore, the surface of the surface has been replaced by P (1) lene terephthalate (PET). The reason for this transparent conduction depends on the hard-to-electric panel (τ_ panel). Therefore, the transparency, bending, and durability should be further considered, and the high temperature and high humidity that may be generated in the prison should be considered. Harsh environmental conditions. The transparent conductive film which is described in (10) is formed by a transparent substrate of the above-mentioned valve material having a layered layer on the surface of the substrate; as shown in FIG. 1, the transparent conductive film 1 has a transparent plastic The substrate i made of a material has a plurality of layers 12 on the surface of the substrate 1 1 , and the laminate i 2 includes a conductive layer 121, a hard coat layer 2 2 and a subsequent treatment layer m. The material of the oxide (Indiun ιιη 〇他' TM) is mainly composed of a field air listening method, a Gu method, an ion coating method, a spray pyrolysis method, an electroless plating method, a shovel method, or a combination thereof. 201029021 Among them, the vacuum evaporation method and the splashing method are difficult. The hard coating 1 2 2 is used to prevent the occurrence of gambling, gambling and cattle _ county, and (4) the material of the hard-rubber-like resin, and the formation of the hard coating 122 also has the function of anti-glare - Η Η (4).

In addition, the current consumption of resistors and electric valley touch panel industry for the requirements of transparent conductive film material suppliers, the general requirements b* value should be less than 3, but in some of the higher shape In the county, the age-changing department has no hope that the color deviation will be smaller, and even the Shiwei show that the Guankeguan is blue, and this demand trend has gradually become one of the main goals of the product pursuit of excellence. 201029021 [Invention] The present invention relates to a substrate having a transparent surface of a touch panel having a thickness of 2 layers, a layer of _, _, and _ layers formed on the surface of the conductive film substrate. Wherein, the conductive number in the laminated body is mainly composed of a material having a thickness of about 15 nn^75 nm θ, or a layer of material in addition to the conductive layer in Zhao, (Qing), a coloring matter or a toner, and It is expected to be between n (four) of the visible light. When the light source rides over the electricity, the color of the colorant or the toner _, ___ read the time, the b* value of the coordinate will fall between -i 〇gb*, when the display is white or partial Blue color. [Embodiment] The present invention relates to a conductive film of a --control panel. As shown in FIG. 4, the transparent conductive film 2 has a substrate 21 of a transparent material, and the surface thereof has a product of a complex touch layer. Ship 2 2. New 2 1 reading quality domain __, but with polyethylene terephthalic acid S (P〇lyethyleneTerephthaiate, yang-based species of petal is preferred, its thickness is between 2 (four) to 300 (four), and the best The system is between 1 G qing and (10) (4). Each of the dreams in the body 2 2 includes at least a conductive layer 221, a hard coat layer 22 and a subsequent treatment layer. The conductive layer 2 2 1 is used to conduct current 'to TM The material is mainly, the thickness is about from 201029021 to 75nm, and then the treatment layer 2 2 3 is between the conductive layer 2 2 1 and the hard coating 2 2 2 to make the conductive layer 21 and hard The coating 2 2 2 is used for the production of the two. The subsequent treatment layer 2 2 3 is mainly composed of a transparent adhesive, and the hard coating 2 2 2 is mainly composed of a hardened resin material such as melamine resin or amine hydrazine. An acid ester resin, an alkyd resin, a resin, an acrylic resin, a polyoxyl resin, etc., wherein at least one layer other than the conductive layer 21 in the substrate 21 or the laminate 2 in the transparent conductive film 2 of the present invention. Containing a dye, a pigment, a colorant or a toner, and making the transparent conductive film 2 of the present invention transparent in the visible light region except for the conductive layer 2 21 And the b* value of the color coordinates is between 1 〇$b*g 。. The thickness of the middle conductive layer 2 is between about 15 nm and 75 nm, so the b* value is about 1-4. In this way, when the light source is transmitted through the conductive layer 21 in the transparent conductive film 2 of the present invention and other substrates 21 or laminates 2 having dyes, toners or toners, light mixing will occur. Finally, when the display is displayed, the "value of the color coordinates will fall between ~1 〇^别·9". When the display is displayed, its color appears white or blue. As shown in Figure 5, the present invention is capable of Increasing the belief of the derivation and increasing the penetration of the water-decomposing gas into the layer 2 2 of the laminate film of the present invention, and forming a buffer layer 2 2 4 under the conductive layer 2 2 ! The punch layer 2 2 4 may be made of inorganic (10) 2) or organic substances. As shown in Fig. 6, the present invention also discloses a conductive film 2 structured towel, a buffer layer 224 of the laminated body 2 2 and The substrate 2] and the subsequent treatment layer 223. The hard coating layer 22 can be formed. 201029021 The transparent conductive film 2 of the present invention _22# two =: or color ===Γ: Γ, pigment In addition to the conductive layer 221, the color material is in the light; the transparent conductive film 2 of the present invention is now -1 n <hkn sees the red and the b* value table π of the age coordinates, with silk, lin (pi_t ), coloring agent tearing ner (4) plus adding body 2 2 = layer and W_21 plus a plurality of layers of the layered body (10), and into / is a diligent product 2 2 towel list - money a few products Riding the squad. The above-mentioned transparent conductive film for the touch panel of the present invention can improve the shortcomings of the conventional ones by the above-mentioned knots 2, and has improved the efficacy and conforms to the progressive requirements.
