Description

TECHNICAL FIELD The present disclosure relates to a laminate and a spectacle lens. BACKGROUND ART Patent Literature 1 discloses a hard coat film in which a hard coat layer (X), a primer layer (Y), and a surface layer (Z) are laminated in this order on at least one surface of a substrate, wherein the surface layer (Z) has a water contact angle of 110° or more. CITATION LIST PATENT LITERATURE Patent Literature 1: JP 2015-120253 A SUMMARY OF INVENTION The present disclosure relates to a laminate including: a lens substrate; an antireflection layer; an intermediate layer; and a water-repellent layer in this order, wherein the intermediate layer is a vapor-deposited layer formed using an intermediate layer-forming composition, and the intermediate layer-forming composition contains at least one compound X selected from the group consisting of a compound represented by the formula (X1) described later, a hydrolysate of the compound represented by the formula (X1), and a hydrolysis condensate of the compound represented by the formula (X1), and a compound Y which is a compound different from the compound X, has at least one of an amino group and an amine skeleton, and has a silicon atom. DESCRIPTION OF EMBODIMENTS Hereinafter, the present disclosure will be described in detail. A laminate of the present disclosure is excellent in scratch resistance. Although the description of components described below may be made based on representative embodiments of the present disclosure, the present disclosure is not limited to such embodiments. In the present specification, a numerical range represented using "to" means a range including numerical values described before and after "to" as a lower limit value and an upper limit value. In the present specification, when two or more kinds of certain components are present, the "content" of the components means the total content of the two or more kinds of components. In the present specification, regarding numerical ranges that are described stepwise, an upper limit value or a lower limit value described in a certain numerical range may be substituted with an upper limit value or a lower limit value of another stepwise numerical range. Regarding the numerical range described in the present specification, an upper limit value or a lower limit value described in a certain numerical range may be substituted with a value shown in examples. In the present specification, a combination of two or more preferred aspects is a more preferred aspect. In the present specification, the "solid content" of a composition means a component that forms a layer formed using the composition, and when the composition contains a solvent (for example, an organic solvent, water, and the like), the solid content means all of components excluding the solvent. A liquid component is also regarded as the solid content as long as it is the component that forms the layer formed using the composition. The bonding direction of a divalent group described in the present specification is not limited unless otherwise specified. For example, when Y in a compound represented by the formula "X-Y-Z" is -COO-, Y may be -COO- or -O-CO-. The compound may be "X-CO-O-Z" or "X-O-CO-Z". [Laminate] The laminate includes a substrate, an antireflection layer, an intermediate layer, and a water-repellent layer in this order. The laminate may include the antireflection layer, the intermediate layer, the water-repellent layer, and the like on one surface of the substrate, and may include the antireflection layer, the intermediate layer, the water-repellent layer, and the like on both surfaces of the substrate. The intermediate layer is preferably disposed adjacent to the antireflection layer and the water-repellent layer. In other words, the laminate preferably includes the substrate, the antireflection layer, the intermediate layer disposed adjacent to the antireflection layer, and the water-repellent layer disposed adjacent to the intermediate layer in this order. <Substrate> The laminate includes the substrate. Examples of the substrate include a substrate composed of a material selected from an organic material and an inorganic material, and an organic material substrate is preferable. Examples of the organic material include an acrylic acid ester resin, a methacrylic acid ester resin, a thiourethane resin, an allyl resin, an episulfide resin, polycarbonate, a urethane resin, polyester, polystyrene, polyethersulfone, poly-4-methyl-pentene-1, and a diethylene glycol bisallyl carbonate resin (CR-39), and a thiourethane resin, an episulfide resin, or a diethylene glycol bisallyl carbonate resin is preferable. The thiourethane resin is a resin obtained by polymerizing a polyisocyanate compound and a polythiol compound. The polyisocyanate compound is preferably m-xylylene diisocyanate, a mixture of 2,5-bis(isocyanatomethyl)-bicyclo[2,2,1]heptane and 2,6-bis(isocyanatomethyl)-bicyclo[2,2,1]-heptane, isophorone diisocyanate, hexamethy
