Embodiment 1
[0122]
[0123] Black ink (DIC CORPORATION Manufacture, TRC1268) layer (colored layer), obtained decorative layer 1.
[0124]
[0125] In PET with a thickness of 38 μm (manufactured by Toray Industries, Inc., On one side of T60), the coating amount after drying is 0.07g / m 2 In the method, DENATRON P-502S (manufactured by Nagase ChemteX Corporation) containing π-conjugated organic conductive material: poly(3,4-ethylenedioxythiophene) was coated, and it was carried out at 130° C. for 30 seconds using a dryer. processing. Thus an antistatic layer was formed.
[0126] Next, on the opposite surface, the weight after drying becomes 0.1g / m 2 In this way, a release agent consisting of 100 parts by mass of a thermosetting silicone (manufactured by Dow Corning Toray Co., Ltd., LTC300B) and 1 part by mass of a catalyst (manufactured by Dow Corning Toray Co., Ltd., SRX212) was applied, thereby A release agent layer was formed. Thereafter, treatment was performed at 130° C. for ...
Embodiment 2
[0135] In addition to changing the thickness of the adhesive layer 1 to 75 μm, the spacer layer 1 was changed to the spacer layer 2, and the ultraviolet irradiation was made only by a high-pressure mercury lamp, and the illuminance of ultraviolet rays with a wavelength of 365 nm was set to 300 mW / cm 2 , The cumulative light intensity is set to 3000mJ / cm 2 The decorative molded body 2 was obtained in the same manner as in Example 1, except that the laminated body 2 was obtained under the conditions. When the volatile substance contained in the adhesive layer was measured, it was 23 ppm.
[0136]
[0137] In PET with a thickness of 50 μm (manufactured by Toray Industries, Inc., On one side of T60), the coating amount after drying is 0.15g / m 2 Glycerin monostearate was applied using the method, and the process was performed at 130°C for 30 seconds in a drier. Thus an antistatic layer was formed.
[0138] Next, on the opposite surface, the weight after drying becomes 0.1g / m...
Embodiment 3
[0140] Adhesive layer 3 was formed to have a thickness of 25 μm instead of adhesive 1 with adhesive 3, and the illuminance of ultraviolet rays with a wavelength of 365 nm was 4 mW / cm using a chemical lamp. 2 , the cumulative light intensity becomes 100mJ / cm 2 Irradiate from the side of the isolation layer 2, and then use a high-pressure mercury lamp so that the illuminance of ultraviolet rays with a wavelength of 365nm becomes 100mW / cm 2 , the cumulative light intensity becomes 2000mJ / cm 2 The decorative molded body 3 was obtained in the same manner as in Example 2, except that the laminated body 3 was obtained. When the volatile substance contained in the adhesive layer of the laminated body 3 was measured, it was 3 ppm.
[0141]
[0142] In the reaction container of nitrogen atmosphere, add 90 mass parts of 2-ethylhexyl acrylate, 5 mass parts of acrylic acid and 5 mass parts of isobornyl acrylate, use initiator (2,2'-azobis(4-methyl Oxy-2,4-dimethylvaleronitrile)) 0.01 ...
