Problems solved by technology

However, similar to the above-mentioned displays, in these applications, the decrease in product value due to the occurrence of white spots, the decrease in the yield rate, and the decrease in the service life are also problems, so it is required to suppress the aggregation of silver atoms at a high level

Embodiment 1

[0141] (1) Formation of transparent conductive filter laminate film

[0142] made and figure 1 The shown transparent conductive thin-film laminated film has the same configuration. That is, a polyethylene terephthalate film (thickness 75 μm) was used as a transparent substrate, and ITO made of oxides of indium and tin was sequentially laminated on one of its main surfaces using DC magnetron sputtering. filter layer (transparent high refractive index thin film layer) and silver thin film layer (transparent metal thin film layer) to obtain a transparent conductive thin film laminate film. The composition of the transparent conductive thin film laminate film is transparent film substrate (75μm) / ITO(40nm) / Ag(15nm) / ITO(80nm) / Ag(20nm) / ITO(80nm) / Ag(15nm) / ITO( 80nm).

[0143] Here, in the formation of ITO, an indium oxide-tin oxide sintered body (In 2 o 3 :SnO 2 =90:10 (mass ratio)), and an argon-oxygen mixed gas (total pressure 266 mPa, oxygen partial pressure 5 mPa) was used a...

Embodiment 2

[0155] Except that the thickness after coating and drying of the protective layer was 1 μm, it was produced in the same manner as in Example 1 to produce an optical filter for a display, and the results of the accelerated corrosion resistance test for this filter were shown in Table 1. middle.

Embodiment 3

[0157] In addition to using a coating liquid composed of polyester resin as a binder material and zinc oxide / antimony oxide as inorganic fine particles (trade name: Sumitomo Osaka Sementos Misefin) as the coating liquid, the thickness of the protective layer is 0.1 Except for μm, an optical filter for a display was fabricated in the same manner as in Example 1, and the results of the accelerated corrosion resistance test performed on the optical filter in the same manner are shown in Table 1.

Abstract

A transparent and conductive laminate that is substantially decreased in reactive defects, and a display filter, a heat-ray reflecting film and an electromagnetic wave-shielding film comprising the laminate are provided. The laminate includes a transparent substrate, a transparent conductive thin-film layer containing silver, and a protective layer containing a binder material and inorganic fine particles, wherein the transparent conductive thin-film layer is in contact with the protective layer. The generation of reflective defects can be outstandingly reduced. Therefore, a laminate superior in electromagnetic wave-shielding ability, heat-ray reflecting ability and visibility for a long period of time and products comprising the laminate can be obtained.

Description

technical field [0001] The present invention relates to a laminate, and further relates to an optical filter for a display. More specifically, it relates to high-quality, durable transparent conductive laminates and optical filters for displays. Background technique [0002] With the progress of the multimedia society and the digital society, the information to be sent and distributed, or the image information or digital information to be processed are all increasing rapidly. Therefore, the importance of the display device of the monitor for displaying them is increasing as an interface device, or as a key device, which connects people and communication equipment, image equipment, computer, etc. [0003] As such a display device, instead of the heavy and thick cathode ray tube (CRT) monitor that is difficult to enlarge in the past, various thin displays are being researched. In particular, thinning and large-screen display can be relatively easy Realized plasma display pan...
