Gravure printer on B (plate depth 35μm, helio plate)
The coating was applied to a dry film thickness of 0.7 μm and dried at 100° C. for 1 second.

ＤＩＣ製、ＰＯＰ−ＶＩＰ、紅、藍、墨、黄テアッた。When we measured the quality of the coated synthetic paper, we found that synthetic paper A had a surface resistivity of 3 x 109 Ω, and the value after one year was 5
X 1.09Ω, no decrease in surface resistance was observed, and the humidity dependence was excellent. Furthermore, there was no coloring caused by antistatic agents, and when the printing suitability was examined using an offset printing machine, there was no bleeding and the printing was clear, and there were no problems at all in the peeling test with tape. The inks used were POP-VIP, red, indigo, sumi, and yellow teat manufactured by DIC.
一方、合成紙Ｂは表面固有抵抗が２Ｘ１０’Ω、１年後

く、印刷テストも良好であった。On the other hand, synthetic paper B has a surface resistivity of 2X10'Ω, a value of 6X1.09Ω after one year, and a value of 2X even at 20% relative humidity.
The resistance was 109Ω, which was as good as synthetic paper A. Further, there was no coloring and the printing test was also good.

成紙Ａ、合成紙已に塗布した。Comparative Example A cationic surfactant "Anstex C-200 (quaternary ammonium salt, manufactured by Toho Chemical Co., Ltd.)" was mixed with water to a ratio of 1/100.
This was applied to synthetic paper A and synthetic paper backing using the same gravure printer as in the example.

度が弱く、使用が困難であった。When the quality of this synthetic paper was measured, the surface resistivity of synthetic paper A was 5 x 10' Ω, but when measured one year later, it had decreased to 3 x 10' Ω, and the relative humidity was 20%.
Inside, it was >5×1012Ω, and the effect was significantly attenuated. Also, as a result of an offset printing test, the tape peel strength was weak, making it difficult to use.
一方、合成紙Ｂも表面固有抵抗が１×１０“０Ωであっ
たものが、１年後には９Ｘ１０”Ωとなり、２０％相対
温度の下では＞５Ｘ１０１ｚΩと充分な効果が認められ
なかった。また印刷適性も不充分であった。On the other hand, synthetic paper B also had a surface resistivity of 1 x 10" 0 Ω, but after one year it became 9 x 10" Ω, and at 20% relative temperature, it was >5 x 10 1 z Ω, indicating that no sufficient effect was observed. Furthermore, the printability was also insufficient.
以上の実施例、 比較例の評価結果をまとめて第 １表に示した。The above examples, The evaluation results of the comparative examples are summarized in this section. It is shown in Table 1.
叙上の通り、本発明によれば、印刷性を阻害することの
