Document Type and Number:
WIPO Patent Application WO/2024/004600
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a method for producing a laminate having excellent wear resistance; and a method for producing an eyewear lens. The method for producing a laminate according to the present invention comprises a step 1 a for forming an intermediate layer (c) on an anti-reflection layer in a substrate (s) having the anti-reflection layer by vapor deposition and a step 2 for forming a water-repellent layer (r) on the intermediate layer (c), in which the intermediate layer (c) is a vapor deposition layer of an organosilicon compound (C) having a silicon atom and also having an amino group and/or an amine skeleton, the water-repellent layer (r) is a cured layer of a mixed composition (ca) of an organosilicon compound (A) having such a structure that a monovalent group having a perfluoroether structure is bound to a silicon atom through a linking group or without a linking group and a hydrolysable group is bound to a silicon atom through a linking group or without a linking group, and the average vapor deposition rate during the formation of the intermediate layer (c) is 0.2 nm/s or more and less than 1.2 nm/s.
