Title:
POLISHING SHEET AND POLISHING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/135180
Kind Code:
A3
Abstract:
Object: To provide a polishing sheet capable of efficiently polishing a hard material such as a metal product so as to form a smooth surface with minimal unevenness. Solution: A polishing sheet (10) including: a substrate (11); a plurality of three-dimensional elements (12) containing abrasive grains and a binding material; and an intermediate layer (13) provided between the three-dimensional elements (12) and the substrate (11) so as to join the substrate (11) and the three-dimensional elements (12), wherein a Young's modulus of the substrate (11) at 25°C is not less than 3.0 x 109Pa; and a Young's modulus of the intermediate layer (13) at 25°C is not less than 1.0 x 107Pa and not greater than 5.0 x 108Pa.
