Document Type and Number:
WIPO Patent Application WO/2023/223827
Kind Code:
A1
Abstract:
A pressure sensitive adhesive sheet 10 is provided with a pressure sensitive adhesive agent layer 3 and a print part 5 formed on at least one surface of the pressure sensitive adhesive agent layer 3. The print part 5 is formed by an ink cured product, and is provided on at least one print region that is set on the pressure sensitive adhesive agent layer 3 as a printing range. In the print region, the loop tackiness value of the pressure sensitive adhesive agent layer 3 with respect to a SUS steel sheet is less than 1.0 N/25 mm. In the print region, the adhesive force of the pressure sensitive adhesive agent layer 3 with respect to a SUS steel sheet at 23°C and at a peel angle of 180 degrees and a relative humidity of 50% when a load of 2 kg was used for pasting the same and after 24 hours has elapsed is 0.05 N/25 mm or more.
