Abstract

Official abstract text for this publication.

A film mirror laminate ( 1 ) includes a substrate film ( 2 ), a metal reflective layer ( 3 ), a reflection adjustment layer ( 4 ), and a water-repellent layer ( 5 ) in order toward one side in a thickness direction. The reflection adjustment layer ( 4 ) includes a silicon oxide layer ( 43 ), and the water-repellent layer ( 5 ) is disposed on one surface in the thickness direction of the silicon oxide layer ( 43 ). Further, a water contact angle in one surface in the thickness direction of the water-repellent layer ( 5 ) is 110° or more.

First claim

Opening claim text (preview).

1 . A film mirror laminate comprising: a substrate film, a metal reflective layer, a reflection adjustment layer, and a water-repellent layer in order toward one side in a thickness direction, wherein the reflection adjustment layer includes a silicon oxide layer, the water-repellent layer is disposed on one surface in the thickness direction of the silicon oxide layer, and a water contact angle in one surface in the thickness direction of the water-repellent layer is 110° or more. 2 . The film mirror laminate according to claim 1 , wherein a reflection rate of a visible ray at a wavelength of 360 to 740 nm irradiated from one side in the thickness direction of the film mirror laminate is 95.0% or more. 3 . The film mirror laminate according to claim 1 , wherein the metal reflective layer includes at least one metal selected from the group consisting of aluminum (Al), zinc (Zn), lead (Pb), copper (Cu), and silver (Ag). 4 . The film mirror laminate according to claim 1 , wherein the reflection adjustment layer includes a low refractive index layer, a high refractive index layer, and the silicon oxide layer in order toward one side in the thickness direction. 5 . The film mirror laminate according to claim 1 , wherein the silicon oxide layer has a thickness of 50 nm or less. 6 . The film mirror laminate according to claim 1 , wherein the water-repellent layer is a dry coating layer. 7 . A mirror member comprising: a support substrate, a pressure-sensitive adhesive layer, and the film mirror laminate according to claim 1 in order toward one side in a thickness direction.
