Title:
Reinforcing film with separator
Document Type and Number:
Japanese Patent JP6366200
Kind Code:
B2
Abstract:
Provided is a reinforcing film with a separator including a reinforcing film and a separator, the reinforcing film with a separator having the following features: peeling electrification that may occur when the separator is peeled can be suppressed; and even when the separator is peeled from the reinforcing film with a separator bonded to the exposed surface side of an optical member, an electronic member, or the like in advance, damage to the optical member or the electronic member can be alleviated. The reinforcing film with a separator includes: a reinforcing film P; and a separator Q, in which: the reinforcing film P includes a base material layer A1 and a conductive component-containing pressure-sensitive adhesive layer A2; the separator Q includes an antistatic release layer B and a base material layer B3; the conductive component - containing pressure-sensitive adhesive layer A2 and the antistatic release layer B are directly laminated; and when the separator Q is peeled from the reinforcing film P in a temperature of 23 DEG C and a humidity of 50%RH at a peel angle of 150 DEG and a peel rate of 10 m/min, a surface of the conductive component-containing pressure-sensitive adhesive layer A2 has a peeling electrification voltage of 3.0 kV or less, and a surface of the antistatic release layer B has a peeling electrification voltage of 1.0 kV or less.
