本発明は、合成樹脂製鏡の製造方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a synthetic resin mirror.
一般に、表面積の比較的小さな合成樹脂製鏡を
製造する場合には、量産性を考慮して、まず表面

基板の一方の面に真空蒸着法などにより金属層を

などで必要な大きさに順次切断することにより、
１枚の鏡から多数の小さな鏡を得るという方法が
採られることが多い。 Generally, when manufacturing a synthetic resin mirror with a relatively small surface area, in consideration of mass production, a transparent synthetic resin substrate with a large surface area is first prepared, and one side of this substrate is coated with a vacuum evaporation method. After forming a metal layer on the metal layer and forming a backing paint layer on the metal layer, a hard coat layer is applied to the other side of the substrate and dried. By manufacturing mirrors and sequentially cutting them to the required size with a cutter,
A method is often adopted in which many small mirrors are obtained from one mirror.

因で、基板と金属層の間および金属層と裏打塗料
層の間に水分等が浸透して金属層が腐食してしま
うという欠点があつた。 However, when it comes to synthetic resin mirrors that are mass-produced using this method, the cut surface remains exposed, and the cut surface undergoes some plastic deformation during cutting. However, there was a drawback that moisture or the like penetrated between the substrate and the metal layer and between the metal layer and the backing paint layer, resulting in corrosion of the metal layer.

金属層の接着性が充分でない場合が多く、このた

属層の腐食に加え、さらに金属層が基板から剥離
しやすくなつてしまうなどの弱点もあつた。 Furthermore, since the surface of the synthetic resin substrate is treated to be extremely smooth in order to increase the reflectance of the metal layer deposited on it, the adhesion of the metal layer to the substrate is often insufficient. Therefore, as mentioned above, if moisture or the like penetrates through the cut surface, it not only corrodes the metal layer, but also causes the metal layer to easily peel off from the substrate.
本発明は、以上のような点を考慮してなされた
もので、量産性を確保しつつかつ金属層の腐食防

方法を提供しようとするものである。 The present invention has been made in consideration of the above points, and it is an object of the present invention to obtain a synthetic resin mirror that can be mass-produced and has sufficiently enhanced corrosion prevention effect and adhesion of the metal layer. The purpose of the present invention is to provide a method for manufacturing a synthetic resin mirror.
以下、本発明の一実施例を添付の第１図〜第５
図を参照して説明する。 Hereinafter, one embodiment of the present invention will be described in the attached Figures 1 to 5.
This will be explained with reference to the figures.

打塗料層３の膜厚は５〜30μ程度が好ましい。 First, as shown in FIG. 1, both sides of a colorless and transparent synthetic resin substrate 1 made of an acrylic casting plate or the like formed to an appropriate thickness are coated with a surface roughness of 0.2 using a chemical or physical method or a mold. The surface of the synthetic resin substrate (hereinafter abbreviated as the substrate) 1 is treated to be smooth so that the thickness is less than On top of layer 2, acrylic, vinyl,
A backing paint layer 3 made of epoxy, polyurethane, or a copolymer thereof mixed with an inorganic or organic opaque pigment is formed by coating or spraying, and is dried to form a flat plate as a whole as shown in the figure. A large synthetic resin mirror A is formed. Here, the material used to form the metal layer 2 is preferably a metal material such as aluminum, silver, or rhodium, which has a high reflectance, and a film thickness of 400 Å or more is sufficient; The thickness of the backing paint layer 3 is preferably about 5 to 30 microns.

ゆる半抜きにした断面Ｖ字状の切欠溝４をカツタ
ーなどで形成する（第２図および第３図参照）。 After forming a large flat plate-shaped synthetic resin mirror A in this way, the next step is to cut the synthetic resin mirror A at the cutting line of the synthetic resin mirror A to cut a large number of small mirrors. As shown in FIG. 2, the backing paint layer 3
A cutout groove 4 having a so-called half-opened V-shaped cross section is formed with a cutter or the like, extending from the top to the inside of the substrate 1 in the thickness direction (see FIGS. 2 and 3).

つても良い。 After the notched grooves 4 are formed on the synthetic resin mirror A, the entire synthetic resin mirror A is immersed in a surface-curing paint made of transparent silicone resin or silicone-acrylic copolymer resin, and then pulled out. This forms a transparent hard coat layer 5 that covers the entire surface of the synthetic resin mirror A including the cutout grooves 4.
(See Figure 4). Note that the method for forming the hard coat layer 5 may be, for example, a method such as coating or spraying instead of the method described above.
このようにして、ハードコート層５を形成した

As shown in FIG. 5, a large number of target small synthetic resin mirrors A' coated with a hard coat layer 5 are obtained.

As shown in FIG. 4, the cut surface is also covered with the hard coat layer 5.
acts as a so-called protective film, preventing moisture etc. from penetrating between the layers from the cut surface. Therefore, corrosion of the metal layer 2 is reliably prevented.
Further, the substrate 1, the metal layer 2 and the backing paint layer 3
is almost entirely covered with the hard coat layer 5, so the substrate 1, metal layer 2 and backing paint layer 3 are reliably integrated with the hard coat layer 5 without peeling off from each other. The overall protection provided by layer 5 significantly improves chemical and physical properties such as chemical resistance, abrasion resistance and corrosion resistance.
また製造工程としても、切欠溝４を入れるいわ

できる。 Moreover, since the manufacturing process essentially only requires the addition of a so-called half-blanking process in which the notched grooves 4 are inserted, mass productivity can be maintained at approximately the same level as in the past.

Needless to say, it can be manufactured in the same manner as .
