example 1

[0046] Various products can be selected for testing, and their fluctuation frequency can be measured by RAYOMETER. Next, an adhesive sheet containing silicon black was attached to each product, and then the fluctuation frequency of each product was measured with RAYOMETER.

[0047] Will image 3 The adhesive sheet with multilayer structure shown was used for the test. The adhesive sheet used was circular, 20 mm in diameter, 90 μm thick, and had a layered structure in which a print protection layer, a print layer containing silicon black powder, a substrate, and an adhesive layer were laminated in this order. Before bonding the sheets, a release paper is temporarily stuck on the surface of the adhesive layer. The substrate is a transparent sheet made of polyethylene terephthalate, a part of the substrate and the adhesive layer have a thickness of 50 μm, based on the total weight of the printing ink, 10% by weight of silicon black is incorporated into the printing Ink. Then ...

example 2

[0051] Several types of adhesive sheets, like Example 1, are all multilayer structures, but the amount ratio of silicon black and the size of the adhesive tape are changed during preparation, and the correlation between the amount of silicon black and the effect obtained is determined. Use a 25-inch TV set with a cathode ray tube as an electromagnetic wave generator, and measure the fluctuating frequency with RAYOMETER at a distance of 2m when the TV set is turned on.

[0052] The measurement results are shown in Table 2. As shown in Table 2, increasing the amount of silicon black, the effect obtained is improved, finally reaching a peak value of 8 Hz.

Abstract

A bad influence of electromagnetic waves, especially, low-frequency electromagnetic waves generated by an electric product, such as a portable telephone upon a human body, and a bad influence of an artificial product upon a human body are minimized. At least a part of an electric product or an artificial product other than the electric product is formed out of a silica black-containing coating material and / or molding material, or a silica black-containing sheet is stuck on either an outer surface or an inner portion of an artificial product. For example, a silica black-containing coating material is applied to the surface of a product, such as a portable telephone and a can of a canned soft drink, a casing of an article is formed out of a silica black-containing plastic, and an adhesive sheet containing silica black is stuck on a product.

Description

field of invention [0001] This invention relates to coating compositions, molding or forming materials and sheets containing Silica black. technical background [0002] There have been some reports published in the past about the harmful effects of electromagnetic waves or radiation on the human body. For example, Dr. Athonova of the Socialist Union of the Soviet Union reported in 1996 the situation of being exposed to ultra-low frequency radiation of 50-cycle frequency or 60-cycle frequency. Furthermore, in 1972 Western countries reported studies of men who worked in power distribution stations suffering from mental and physical disturbances, symptoms that appeared to be caused by exposure to pulsed electromagnetic waves, which Generated by a current that is excited intermittently over time. The research on the application of electromagnetic waves in medicine has been very active and extensive in the 1970s, and the progress of this research has made the influence of elect...
