〔産業上の利用分野〕
本考案は、鏡製品において、光反射層の形状に
関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the shape of a light reflecting layer in mirror products.
従来、鏡製品は、基板としてガラスを使用して
いる。ところが、近年、軽量化、加工性、安全性
等の利点より、プラスチツクの使用が目立つよう
になつてきた（例えば、特開昭56−150704号公
報）。
Conventionally, mirror products use glass as a substrate. However, in recent years, the use of plastic has become more prominent due to its advantages such as light weight, workability, and safety (for example, Japanese Patent Application Laid-Open No. 150704/1983).
基板にガラスあるいはプラスチツクを使用して
も、そのほとんどが裏面鏡であり、その光反射層
は、真空蒸着法等により裏面前面に形成されてい
る。 Even if glass or plastic is used as the substrate, most of them are back mirrors, and the light reflecting layer is formed on the front surface of the back surface by vacuum evaporation or the like.
また、一部には、真空蒸着法等により表面を光
反射層とする表面鏡も利用されている。 In addition, some surface mirrors are used in which a light reflecting layer is formed on the surface using a vacuum evaporation method or the like.
〔考案が解決しようとする問題点〕
表面鏡と裏面鏡を比較すると、裏面鏡の場合

になる。[Problem that the invention aims to solve] Comparing front-facing mirrors and back-facing mirrors, in the case of back-facing mirrors, reflection occurs on the front surface, although there are some differences depending on the type of substrate and the thickness depending on whether or not it is coated. ,
The sharpness of the image and sense of distance will be slightly inferior to that of a surface mirror.

からは吸湿しないので、その結果反りが発生する
ことになる。 In addition, when using plastic as a substrate, some plastics have hygroscopic properties.
When a metal light-reflecting layer is formed on the entire back surface by vacuum evaporation, it absorbs moisture from the front surface and expands, but it does not absorb moisture from the back surface, resulting in warpage.
この反りを防止する方法として一部光反射層の
存在しない微細部分を有する光反射層をもつたプ
ラスチツクミラーが提案されている。しかし、光
反射層の微細形状によつては外観上見苦しいとい
う問題点がある。 As a method for preventing this warping, a plastic mirror having a light reflective layer having minute portions where no light reflective layer is present has been proposed. However, depending on the fine shape of the light-reflecting layer, there is a problem in that it is unsightly in appearance.
本考案者は、上記問題点を解決すべく鋭意研究

FIG. 2 is a partially enlarged side view. In FIGS. 1 and 2, 1 is a substrate, 2 is a transparent surface cured film, 3 is a honeycomb-shaped light reflecting layer, and 4 is a protective coating film.
As the substrate 1, a transparent plastic such as methacrylic resin, polycarbonate resin, styrene resin, polyallyl diglycol carbonate such as CR-39, or cellulose resin is used.
These resins are hygroscopic transparent plastics, and in particular, the transparent plastics shown below have a saturated water absorption rate of 0.3 to 2% at room temperature or when immersed in water.
Within this range, the mirror will not warp.
It is also easy to make mirrors. That is, a homopolymer of methyl methacrylate (saturated water absorption rate: about 2%),
Acrylate copolymers of methyl, ethyl, tert-butylcyclohexyl, tert-butylcyclohexyl, etc. (water absorption 0.7-2%) Copolymers of methyl methacrylate and styrene (water absorption 0.3)
~2%), heat-resistant methacrylic resin containing glutaric anhydride and glutarimide in the polymer molecular chain (water absorption rate 1.0~1.5%), polycarbonate resin (approx.

い。 The saturated water absorption rate is measured by immersing the sample in water at 23°C, measuring the weight increase at which the weight change becomes saturated, and calculating the ratio to the original weight. It may have any shape and may have any thickness.

外線照射法等により塗膜を硬化したものである。 As the surface hardening film 2, a transparent resin such as acrylic or silicone resin is used. The method of forming this cured film on the substrate surface is to apply it to the substrate by dipping, spraying, flow coating, spin coater, roll coater, etc., and then harden it by heating, ultraviolet irradiation, etc. It is something.

難である。 The light-reflecting layer 3 is made of aluminum, copper, silver, chromium, etc., and is formed on one side of the hardened surface film 2 by a vacuum deposition method, a sputtering method, an ion plating method, etc., and the structure of the light-reflecting layer 3 is as follows. It has a honeycomb shape (black member). This honeycomb shape is the first
Triangles are used in addition to the hexagons shown in the figures.
However, in the case of pentagons, polygons larger than heptagons, and circles, it is difficult to increase the area of the light reflective layer to 90% or more if the shapes and sizes are the same. Although it is possible to increase the area of the light-reflecting layer to 90 or more by combining it with other materials, the area of the light-reflecting layer is not constant, which makes it unsightly, and it is difficult to create the pattern.

発生も防止できる。 When the pattern of the light-reflecting layer is triangular or hexagonal, the area of the light-reflecting layer can be easily increased to 90% or more, and the light-reflecting layer can be regularly arranged in the same pattern. In particular, in the case of a hexagon, the first
As shown in the figure, by regularly arranging the same pattern, the parts without a light-reflecting layer are not continuous in a certain direction, and by controlling the size of the light-reflecting layer and the size of the part without a light-reflecting layer, the light The area of the reflective layer can be made close to 100%, resulting in a clear image being projected and preventing warping even when the substrate is made of hygroscopic transparent plastic.
保護塗膜４としては、各種の塗料を希釈溶剤で
希釈し、スプレー法、流し塗り法等により塗布形

あつても構はない。 The protective coating film 4 is formed by diluting various paints with diluting solvents and applying them by spraying, flow coating, or the like. Further, it may be hygroscopic.

As mentioned above, by forming the light-reflecting layer into a honeycomb shape, (1) the pattern of the light-reflecting layer and the part without the light-reflecting layer is regularly arranged, and the area of the light-reflecting layer is 90% or more; As a result, a clear image comparable to that of a rear mirror with a reflective layer on the entire surface is projected, giving a clear sense of distance. In addition, (2) since they have the same regular pattern, the pattern can be easily manufactured, and (3) the area of the light-reflecting layer can be set freely, resulting in excellent fashionability. Furthermore, (4) when using plastic with moderate hygroscopicity, it absorbs moisture from parts without a light-reflecting layer, so there is no warpage, and it is easy to manufacture, which was unexpected. It has a big effect.
