Title:
ULTRAVIOLET-CURABLE ADHESIVE AND LAMINATION METHOD AND ARTICLE USING THE SAME
Document Type and Number:
Japanese Patent JP2018012750
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet-curable resin composition having good application property and curability, suppressing not only air bubbles on an interface between an optical member and the resin composition upon lamination but air bubbles generating in the resin composition, and giving high visibility, and a production method of an article using the composition.SOLUTION: (1) An ultraviolet-curable adhesive composition for a touch panel is provided, which is a resin composition for a touch panel and having the following characteristics. After the resin composition is put in a vessel in an environment at 25°C and air bubbles are mixed in the composition by agitating with a dispersion mixer at a speed of 200 rpm for 30 minutes, the vessel is put in a bell-shaped vacuum defoaming device to subject the composition to a reduced pressure environment of 500 Pa inner pressure. The time period until bubbles having a size of 100 μm or more disappear is 30 minutes or shorter.SELECTED DRAWING: Figure 1
