example 1

[0054] Paint-1 to Paint-4 shown below were prepared.

[0055] ·Paint-1

[0056] Commercially available organic solvent-soluble amorphous polyester resin (hereinafter referred to as "polyester resin") "Bairoso (TM) GK140" (number average molecular weight: 13000, Tg: 20°C) manufactured by Toyobo Co., Ltd. was dissolved In an organic solvent (solvent 150 and cyclohexanone mass ratio of 1:1 mixed solvent). To the obtained solution, "Symel (trademark) 303" manufactured by Mitsui Cytech Co. 15 parts by mass (converted by solid content), and then add 0.5 parts by mass (calculated by solid content) of "Catalyst 6003B" manufactured by Mitsui Siteck Co., Ltd. Polyester-based clear paint. Furthermore, 50% by mass (in terms of solid matter) of titanium oxide "Tipe-ku (trademark) CR95" manufactured by Ishihara Sangyo Co., Ltd. was added to the prepared clear paint and stirred to obtain Paint-1.

[0057] Here, the term called parts by mass means the ratio (the unit is the number of part...

example 2

[0108] Using the same paint and metal plate as used in Example 1, a reflective plate was fabricated.

[0109] The white resin sheet used in this example was produced as follows. In addition, the thickness of the bonded resin sheet was 200 micrometers.

[0110] (1) White tablet PP-3

[0111] To the commercially available polypropylene resin "IDEMI TSU PPF-734NP" manufactured by Idemitsu Petrochemical Co., Ltd., 29.5% by mass of titanium oxide "タイペ-ク (trademark) CR95" manufactured by Ishihara Sangyo Co., Ltd. was added, and 0.5% by mass % Carbon black "ト-カブラッック#7350F" manufactured by Tokai Ka-bon Co., Ltd. is uniformly mixed and vacuum-dried sufficiently, and the obtained dried product is supplied to an extruder equipped with a T-die for sheet molding. In the machine, melt extrusion was carried out at a temperature above the melting temperature of the resin and below the temperature at which the resin decomposed, and was guided to a chill roll and a drawing roll to obtain a wh...

Abstract

There are provided a new visible ray reflection plate capable of making the light from a lighting device and an electric / electronic device emitting a light signal brighter and an electric / electronic device using the new visible ray reflection plate. The visible ray reflection plate (1) includes a white resin sheet (5) superimposed on a metal plate (3) which may be plated wherein the area ratio of air bubbles existing at the boundary between the white resin sheet (5) and the metal plate (3) which may be plated is not greater than 5%. Alternatively, the visible ray reflection plate (1) includes a white resin sheet (5') having a visible ray diffuse reflectance of 0.07 or above at the surface of 555 nm and infrared total radiation ratio 0.60 or above at the area of the wave number 600 to 3000 cm<-1> measured at a predetermined temperature from 80 degrees C to 200 degrees C which resin sheet is arranged on one side of the metal plate (3) which may be plated.

Description

technical field [0001] The present invention relates to a visible light reflecting plate, and also relates to a device having a function of emitting visible light and having a plate capable of reflecting the emitted visible light, said device being a lighting appliance, an AV device, a mobile device, a plasma display , LCD TVs and other electrical and electronic equipment. Background technique [0002] Lighting fixtures, AV equipment, electronic equipment, mobile equipment, liquid crystal televisions, plasma displays, etc., have the functions of illuminating the surroundings, transmitting optical signals, or reflecting optical images by emitting visible light. Some of these devices are also equipped with a reflector, and by making the reflector reflect light, the brightness of the light can be improved, the direction of the light can be changed, and the like. In order to avoid a decrease in the amount of light when light is reflected by the reflective plate, it is required ...
