Title:
防汚層付粘着テープ
Document Type and Number:
Japanese Patent JP5486625
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive tape with an antifouling layer, which is excellent in reworkability when being executed such that rework is performed with good finish by peeling off, even when it is adhered by mistake, and fixability to an adherend can be sufficiently obtained when being stuck in a stretched state.SOLUTION: An adhesive tape with an antifouling layer includes an antifouling layer, a substrate layer, and an adhesive layer in this order. The stress residual ratio of the substrate layer at 80 degree C is higher than that of the substrate layer at 20 degree C, and the difference between the stress residual ratio at 20 degree C and that at 80 degree C is 35% or more. Here, the stress residual ratio of the substrate layer, in each of the temperatures, is a value obtained in such a way that the adhesive tape with the antifouling layer having a width of 10 mm and a test length of 50 mm is stretched by 20% (10 mm) at the rate of 200 mm/min, a stress right after stretching and a stress after 150 s from stretching are measured, and then (stress after 150 s from stretching/stress right after stretching)×100 is calculated.
