ＣＢ） イソインドリノンエロー
Ｃ） フラバンスロンエロー
■ セイ力ファーストイエロー２５００Ｈ３
第１表から明らかな通り、本発明の範囲にある実施例１
〜４ではいずれも良好な絶縁抵抗、色相および色相の熱
安定性を示す。Table 1 CB) Isoindolinone Yellow C) Flavanthrone Yellow■ Seiryoku Fast Yellow 2500H3 As is clear from Table 1, Example 1 within the scope of the present invention
-4 all exhibit good insulation resistance, hue, and thermal stability of hue.
これに対し、比較例１は汎用の赤色着色剤を添加したも
のであるが、絶縁抵抗および初期の色相は良好であった
が、耐熱性が悪く、２５０℃で４日熱劣化すると脱色し
てしまった。On the other hand, in Comparative Example 1, a general-purpose red coloring agent was added, and although the insulation resistance and initial hue were good, the heat resistance was poor, and the color faded after 4 days of thermal deterioration at 250°C. Oops.
比較例２および３は、無機系耐熱黄鉛酸化チタンを添加
したものであるが、添加量が２ ｐｈｒでは良好な色相
が得られず、１ｏｐｈｒと多量添加すると絶縁抵抗が大
きく低下してしまう。In Comparative Examples 2 and 3, inorganic heat-resistant yellow titanium oxide was added, but if the amount added was 2 phr, a good hue could not be obtained, and if it was added in a large amount of 1 ophr, the insulation resistance would be significantly reduced.
