- Tg glass transition temperature
- “storage modulus” is a value measured under auto strain conditions at a shear rate of 1 rad/sec and strain of 1% using a rheometer (ARES G2 manufactured by TA), which is a dynamic viscoelasticity measuring device. Specifically, a plurality of adhesive layers were laminated to prepare a sample to a thickness of 800 ⁇ m, and a specimen was prepared by puncturing the laminate with a perforator having a diameter of 8 mm. It is a value measured while increasing the temperature at a temperature of -60°C to 90°C with a force applied at a temperature increase rate of 5°C/min.
- peel strength refers to FIG. 7, an adhesive layer 6 on a high-strength glass plate 7, using a corona treatment machine, while discharging plasma at a dose of 78 dose (total dose: 156 dose)

- a specimen of FIG. 7 was prepared, and the prepared specimen was maintained at 25° C. for 30 minutes.
- the specimen was fixed to a peel strength measuring instrument TA.XT_Plus Texture Analyzer (Stable Micro System (manufactured by Stable Micro System)), and the peel strength of the specimen was measured at 25° C. and measured according to FIG. 8 .

- the adhesive layer 6 is peeled from the high-strength glass plate 7, the peel strength is measured.
- X to Y means X or more and Y or less (X ⁇ and ⁇ Y).
- the optical laminate of the present invention includes a second adhesive layer, a first adhesive layer stacked on the second adhesive layer, and a light blocking unit stacked between the second adhesive layer and the first adhesive layer.
- the first adhesive layer and the second adhesive layer are formed to face each other.
- the optical laminate of the present invention can simultaneously perform a function of adhering different first and second adherends to each other and a function of realizing a non-display area and a display area when applied to an optical display device.
- the first adherend is defined as being laminated on the first adhesive layer
- the second adherend is laminated on the second adhesive layer.
- the "reworkability" is to prepare a specimen by laminating an optical laminate cut to length x width (100mm x 100mm) so that the second adhesive layer is laminated to a high-strength glass plate, and place the prepared specimen on a hot plate at 80 ° C.
- the optical laminate of the present invention has excellent reworkability, particularly high temperature reworkability, since there is no residue of the second adhesive layer in the high-strength glass plate and the optical laminate is not destroyed at the time of the above determination.
- the “foldability” can be evaluated by the following method.
- a module specimen laminated in the order of a window film, an optical laminate, and an OLED panel was prepared.
- the following window films, optical laminates, and OLED panels were used in manufacturing the module:
- PET film (thickness: 100 ⁇ m, Cosmoshine TA015, Toyobo) was replaced.
- PET film thickness: 100 ⁇ m, Cosmoshine TA015, Toyobo was replaced.
- the prepared module specimen was cut to length x width 170 mm x 110 mm and folded 100,000 times at -20 °C, it was evaluated whether air bubbles, cracks and delamination occurred in the module specimen.
- folding the module specimen was folded in the longitudinal direction and the OLED panel direction, and the radius of curvature was 1.5 mm at the time of folding, and 30 cycles per minute were folded. In this case, 1 cycle means that the specimen is folded to the radius of curvature and unfolded at 180°. Foldability can be evaluated at 25°C.
- the optical laminate of the present invention may implement excellent foldability because bubbles, cracks, and delamination do not occur during the above evaluation.
- the optical laminate of the present invention is manufactured by the method described in detail below, the effect of processability and cost reduction is excellent. That is, the method of simultaneously forming a plurality of cells including a light-shielding part (for example, the light-shielding part 30 in FIG. 1 ) on a base film or a window film by a conventional roll-to-roll method is a method of forming a print flow pattern or printing between cells including a light-shielding part. As the number of base films or window films that are discarded inevitably occur due to defective phenomena including bleeding, etc., it has been a factor of cost increase. However, the optical laminate of the present invention does not have the above-mentioned problems, and thus has excellent processability and cost reduction effects.
- FIGS. 1 and 2 an optical laminate according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2 .
- the optical laminate includes a first adhesive layer 10 , a light blocking unit 30 , and a second adhesive layer 20 .
- the light blocking part 30 is formed on at least a portion of the interface between the first adhesive layer 10 and the second adhesive layer 20 . Specifically, the light blocking part 30 is impregnated in the interface between the first adhesive layer 10 and the second adhesive layer 20 .
- impregnation is, as shown in FIG. 1, the light blocking part 30 penetrates a part of the first adhesive layer 10 and exists in the first adhesive layer 10 while the second adhesive layer 20.
- the light blocking portion 30 penetrates a portion of each of the first adhesive layer 10 and the second adhesive layer 20 to the first adhesive layer 10 ) and the second adhesive layer 20 is a concept including the case present inside. Since the light blocking part 30 is not formed as a separate layer compared to the first adhesive layer 10 and/or the second adhesive layer 20 , the optical display device may be reduced in thickness.
