Abstract

See full text

An object of the present invention is to provide a laminate which has a substrate, an intermediate layer, and a water-repellent layer laminated in this order, and has excellent abrasion resistance. The present invention is a laminate comprising: a substrate (s) having an anti-reflection layer; an intermediate layer (c) placed on the anti-reflection layer side of the substrate; and a water-repellent layer (r), in this order, wherein the intermediate layer (c) is a cured layer of a mixture composition (cc) of an organosilicon compound (C), or a vapor deposition layer of the organosilicon compound (C), the organosilicon compound (C) contains a silicon atom together with an amino group and/or an amine skeleton, the water-repellent layer (r) is a cured layer of a mixture composition (ca) of an organosilicon compound (A) in which a monovalent group having a perfluoropolyether structure is bound to a silicon atom through a linking group or without a linking group located therebetween, and a hydrolyzable group is bound to the silicon atom through a linking group or without a linking group located therebetween, and the laminate satisfies the following requirement (1),

    (1) a water sliding angle is not larger than 50° after a abrasion resistance test in which a 200 g load per 1.5 cm×1.5 cm area is applied to a surface on the water-repellent layer (r) side of the laminate and the surface is rubbed 20,000 times.
