LEATHER-LIKE SHEET

Document Type and Number:

WIPO Patent Application WO/2021/131589

Kind Code:

A1

Abstract:

This leather-like sheet comprises: a fiber base material; an intermediate resin layer layered on one surface of the fiber base material; and a surface resin layer layered on the intermediate resin layer. The surface resin layer contains a polyether polyurethane and spherical fine particles having heat resistance at 200°C, the content ratio of the spherical fine particles being 5 to 40% by mass. The spherical fine particles have a specific heat of 0.95 kJ/(kg·K) or more. Particle size D50 (median diameter), at the cumulative distribution of 50% by volume, is 2.5 to 10 μm. Particle size {D10, at the cumulative distribution of 10% by volume, satisfies D50/D10≤3 which is a particle size dispersion degree.
