Document Type and Number:
WIPO Patent Application WO/2021/182461
Kind Code:
A1
Abstract:
Provided is a laminate in which when a crack occurs on the surface, the crack is easier to find at an early stage. The laminate (tread 11) is provided with an inner layer 12 that is made of a molded resin, and an outer layer 13 that is laminated on the outside of the inner layer 12 and that is made of reinforced fiber. The inner layer 12 has a first color on the surface on which the outer layer 13 is laminated. The outer layer 13 has a second color on the outside surface. The color difference between the first color of the inner layer 12 and the second color of the outer layer 13 is at least 40 in the CIELAb color space. When a crack occurs in the outer layer 13, the color difference makes it easier to see the crack. As a result, it becomes possible to repair or replace the cracked tread 11 at an early stage.
