METHOD FOR MANUFACTURING LAMINATE FOR CONSTITUTING IMAGE DISPLAY DEVICE, AND IMAGE DISPLAY DEVICE USING THE LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate for constituting an image display device, which can simultaneously achieve irregularity conformability and foaming resistance reliability.

SOLUTION: An ultraviolet-curing transparent double-sided adhesive sheet which has been ultraviolet-crosslinked while remaining ultraviolet reactivity has an indentation hardness (C2 Asker hardness) (a) in the range of 10≤(a)<50. Further irradiation of ultraviolet rays can raise the indentation hardness (C2 Asker hardness) of the sheet. The adhesive sheet is formed of an adhesive composition containing at least an intermolecular hydrogen abstraction-type photopolymerization initiator.
