Example Embodiment
[0213] Example 1
[0214] like figure 1 As shown, TAC film (thickness 65 μm, first transparent resin film), acrylic pressure-sensitive adhesive layer (thickness 23 μm, first pressure-sensitive adhesive layer), infrared reflection layer, λ / 4 plate (thickness 50 μm, first 1 / 4 wavelength layer), acrylic pressure-sensitive adhesive layer (thickness 23μm, third pressure-sensitive adhesive layer), TAC film (thickness 40μm, second transparent resin film), polarizer (thickness 22μm, iodine-impregnated PVA), λ / 4 plate (thickness 50 μm, second 1 / 4 wavelength layer), acrylic adhesive layer (thickness 23 μm, fourth adhesive layer), UV absorber-containing TAC film (thickness 60 μm, third transparent resin film ) were stacked so as to be arranged in order from the bottom, and the polarizing films of the examples were produced.
[0215] In addition, as the infrared reflection layer, amorphous ITO (thickness 40 nm, first inorganic oxide layer), silver-copper alloy (thickness 8 nm, metal ...
Example Embodiment
[0217] Example 2
[0218] Except having changed the thickness of the metal layer of the infrared reflection layer to 12 nm, it carried out similarly to Example 1, and produced the polarizing film and the protective plate for image display devices.
Example Embodiment
[0219] Example 3
[0220] Except having changed the thickness of the metal layer of the infrared reflection layer to 20 nm, it carried out similarly to Example 1, and produced the polarizing film and the protective plate for image display devices.
