望ましい。When the transparent window plate body 1 is made of plastic, it is desirable, although not essential, to form an undercoat film on the surface (one side) of the window plate body 1 on which the sputtered film is to be formed. After steam cleaning or spray cleaning the surface of the transparent window plate main body 1 with a chlorinated solvent such as trichlorotrifluoroethane, the undercoat film 3 is applied to a polyurethane-based, acrylic-based, polyester-based, or
It is obtained by spraying or dipping coating with a clear (highly transparent) undercoating paint such as silicone-based or melamine-based paint, followed by heating and drying, and the film thickness is usually 4 to 15 μm. When coating both sides by dipping, use melamine-based
A silicone-based or acrylic-based hard coat paint is desirable from the standpoint of preventing scratches on the side on which the sputtered film is not formed.

A sputtered film 5 made of a conductive metal with a thickness of 100 nm) is formed. Here, if the film thickness is less than 12 nm, heat rays (near infrared rays)
If the blocking effect is insufficient and the film thickness exceeds 35 nm, visible light will hardly be transmitted, which is undesirable.

るまでの電気量（電流量）によりほぼ塗装厚は決まる。(3) The top surface of the sputter@5 has a film thickness of 1 to 60 μm.
A pigment-containing electrodeposited heavy film 7 (preferably 5 to 30 μm) is formed. Here, if the film thickness is less than 1 μm, the absolute amount of pigment is insufficient and there is almost no effect of reducing the reflectance, and if it is 60 μm or more, the leveling property is poor and the transmittance is also poor, which are both undesirable. The pigment content is the customary amount (O, OS~2
．． Owt%). The electrodeposition paint that forms the above electrodeposition coating film can be either anionic or cationic, but from the standpoint of maintaining a good appearance over a long period of time, a coating film with excellent weather resistance, corrosion resistance, and high hardness can be obtained. Anionic acrylic or melamine paints are preferred. Electrodeposition coating is
In electrodeposition coating, which is performed under conditions of a voltage of 15 to 50V, a liquid greenhouse temperature, and an electrodeposition time of 2 to 5 minutes to achieve a predetermined coating thickness, almost no current flows once a coating film is formed. Since electrodeposition is no longer performed, the coating thickness is approximately determined by the amount of electricity (current amount) until the coating film is formed.
従って、スパッタ塗膜、スパッタ金属の抵抗率及び塗装
電圧を適当に選定することにより塗装厚を設定できる。Therefore, the coating thickness can be set by appropriately selecting the sputtered coating film, the resistivity of the sputtered metal, and the coating voltage.

Can be used for sunroofs and side windows. In this case, the surface on which the coating film is formed is usually the inside of the vehicle from the viewpoint of wear resistance, but it may of course be on the outside of the vehicle.

しさを感じない５％以下となっている。<Operations and Effects of the Invention> As described above, the transparent window plate for automobiles of the present invention has a sputtered film made of a conductive metal having a thickness of 12 to 35 nII+ formed on one side of the main body of the transparent window plate. The transparent window plate for automobiles having the structure of the present invention, which has the structure in which a pigment-containing electrodeposited coating film with a film thickness of 1 to 60 μm is formed on the upper surface and exhibits the following functions and effects, is as shown in the below-mentioned Examples (Second Example). ), the transmittance is significantly reduced not only in the visible light region (λ=380-780 nm) but also in the near-infrared region (λ=780-2000 nm). Furthermore, the reflectance (electrodeposition coating surface) is 5% or less in the visible light range, at which the viewer does not feel glare, as shown in FIG.
従って、本発明の自動車用透明窓板は、熱線遮断効果が
従来に比して増大し、かつ、光侵入側にいる看者にもま
ぶしさを感じさせることがない。Therefore, the transparent window panel for automobiles of the present invention has a heat ray blocking effect that is higher than that of the conventional window panel, and does not cause glare to the viewer on the side where the light enters.
上記効果を奏する理由は、断定できないが、下記の如く
であると推定される。The reason for the above effect cannot be determined, but it is presumed to be as follows.
電着塗装時、スパッタ膜中の金属の溶出（金属イオン化
傾向が大きい程溶出しやすい）による膜厚の低減、電Ｓ
塗膜中の顔料による光吸収、及び、電着塗膜の高いレベ
リング性が協働して、可視光線の反射率の低下が招来さ
れ、しかも、近赤外線領域での透過率も大幅に低減して
大きな熱線遮断効果を奏する。During electrodeposition coating, reduction in film thickness due to elution of metal in the sputtered film (the greater the metal ionization tendency, the easier it is to elute),
The light absorption by the pigment in the coating film and the high leveling properties of the electrodeposition coating film work together to reduce the reflectance of visible light, and also significantly reduce the transmittance in the near-infrared region. It has a great heat ray blocking effect.
