１０重量部までは成形性も問題ないことが分かる。Further, the addition amount of the near-infrared absorbent grade SIR-132 is 1 with respect to 100 parts by weight of the ABS resin.
A composition having a composition of 0 -3 , 10 -2 , 10 -1 , 1 , 10, 15 parts by weight was kneaded by heating with an injection molding machine and injection molded to form a card having a thickness of about 0.8 mm. Then
With formability and writer, it was evaluated by whether or not detection voltage card insertion is determined to clearly obtained, although the SIR-132 has poor formability made by adding 15 parts by weight, 10 - Those having added 3 , 10 -2 , 10 -1 , 1, 10 parts by weight had good moldability. When 10 -3 and 15 parts by weight were added, the infrared absorption effect was not sufficient because the voltage was below the specified detection voltage, but when 10 -2 , 10 -1 , 1, 10 parts by weight were added, it was judged that the card insertion was clear. The detected voltage obtained was obtained. From the above, if a near infrared absorber having an absorption wavelength near the wavelength of the semiconductor laser used for the infrared light emitting diode of the reader / writer, ABS is used.
If the addition amount of 10 −5 parts by weight or more is added to 100 parts by weight of the resin, there is an absorption effect and there is no problem in moldability.
In addition, even with a near-infrared absorber having an absorption wavelength far from the wavelength of the semiconductor laser, if 10 -2 parts by weight or more is added to 100 parts by weight of the resin, the absorption effect is observed, and the addition amount is up to 10 parts by weight. It can be seen that there is no problem in moldability.
