- Cure Shrinkage (%) (B-A) / B ⁇ 100
- A is the specific gravity of the composition before photocuring
- B is the specific gravity of the cured product formed by photocuring the composition for the optical transparent adhesive.
- E-type hardness was evaluated by the following method about the image display apparatus manufactured as mentioned above using the composition for optical transparent adhesives manufactured by the said Example 1-3 and the comparative example 1-2.
- a metal halide lamp (Dymax, 5000 EC) is used to irradiate light back and forth with 3,000 mJ / cm 2 light. After the solid adhesive is separated from the Teflon mold and cooled to room temperature, the hardness is measured with an ASKER E hardness tester.
- Reliability was evaluated by the following method about the image display apparatus manufactured as mentioned above using the composition for optical transparent adhesives manufactured in the said Example 1-3 and the comparative example 1-2.
- Measuring method At a high temperature and high humidity of 60 ° C. and 90% relative humidity from the time point at which each of the image display apparatuses was manufactured, it was left for at least 240 hours, and then the respective edges of the glass substrate were driven after driving the respective image display apparatuses. Observation was made with the naked eye to observe whether there was a part that discolored to yellow, and the case where yellowing occurred due to the color discoloration to yellow was indicated by " ⁇ ", and the case where it did not occur was indicated by " ⁇ ".
- Example 1 The result of Example 1 was the most excellent, and it was confirmed that the yellowing phenomenon was prevented as the content of the monomer in the photocurable composition for optical adhesives was less.
