DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE SHEET AND ABRASIVE CLOTH LAYERED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an abrasive cloth-fixing pressure-sensitive tape that is capable of forming an abrasive cloth laminate body that causes no marked stress relaxation in no need of many-hour immersion of the abrasive slurry before the abrasion and causes no swelling deformation due to the abrasive slurry during the abrasion and provide an abrasive cloth laminated body.

SOLUTION: This double-sided pressure-sensitive sheet has a thickness difference per 1 m2between the maximum thickness and the minimum thickness of ≤ 100 μm, the compression stress damping factor of ≤ 15 % that is measured from the maximum compression stress in the compression test in which the compression distance after compression is kept constant and the compression stress value after 0.1 second after the maximum value is obtained. The abrasive cloth laminated body comprises the double-sided pressure sensitive sheet and a pressure-sensitive adhesive layer that is laminated on any one face of the double-sided pressure sensitive layer.
