PRESSSURE-SENSITIVE ADHESIVE SHEET |
| 摘要 |
A pressure-sensitive adhesive sheet has a substrate and a pressure-sensitive adhesive layer laminated on at least one side of the substrate. The pressure-sensitive adhesive layer contains a (meth)acrylic polymer having a weight average molecular weight of 10000 or more but less than 50000. Pressure-sensitive adhesive force, occurring after 30 minutes since the pressure-sensitive adhesive layer was attached to an ABS plate, is 1.0 [N/20 mm] or less, pressure-sensitive adhesive force, occurring after 24 hours since the pressure-sensitive adhesive layer was attached to an ABS plate, is 2.5 [N/20 mm] or less, and pressure-sensitive adhesive force, occurring after 30 minutes at 23° C. since the pressure-sensitive adhesive layer was attached to an ABS plate and then heated at 80° C. for 5 minutes, is 6.5 [N/20 mm] or more. |

1. A pressure-sensitive adhesive sheet comprising:
a substrate; and a pressure-sensitive adhesive layer laminated on at least one side of the substrate, wherein the pressure-sensitive adhesive layer contains a (meth)acrylic polymer having a weight average molecular weight of 10000 or more but less than 50000, and wherein. pressure-sensitive adhesive force, occurring after 30 minutes since t=he pressure-sensitive adhesive layer was attached to an ABS plate, is 1.0 [N/20 mm] or less, and wherein pressure-sensitive adhesive force, occurring after 24 hours since the pressure-sensitive adhesive layer was attached to an ABS plate, is 2.5 [N/20 mm] or less, and wherein. pressure-sensitive adhesive force, occurring after 30 minutes at 23° C. since the pressure-sensitive adhesive layer was attached to an ABS plate and then heated at 80° C. for 5 minutes, is 6.5 [N/20 mm] or more. |
