が知られていた。BACKGROUND ART Conventionally, varnishes made using polyimide resins such as polyimide, polyamideimide, and polyesterimide alone have been known.
しかしながら、かかるワニスを厚塗りして焼付処理する
と発泡する問題点があり、発泡を有しない焼付層を形成
するためには塗り厚さをlo−以下に制御する必要があ
った。そのため例えば1ossを超える焼付層を形成す
るためには、ワニスの塗布とその焼付処理を10回以上
繰り返す必要のある問題点があった。However, if such a varnish is applied thickly and baked, there is a problem in that it foams, and in order to form a baked layer without foaming, it is necessary to control the coating thickness to less than lo-. Therefore, for example, in order to form a baked layer exceeding 1 oss, there is a problem in that it is necessary to repeat the application of varnish and the baking process ten or more times.
課題を解決するための手段
本発明らは前記の課題を克服し、厚塗り焼付しても発泡
問題を生じないワニスを開発するために鋭意研究を重ね
た結果、意外にもポリアミドイミドを所定の割合で用い

の目的を達成できることを見出し、本発明をなすに至っ
た。Means for Solving the Problems As a result of extensive research in order to overcome the above-mentioned problems and develop a varnish that does not cause the foaming problem even when thickly coated and baked, the present inventors unexpectedly found that polyamide-imide was It was discovered that the object could be achieved by creating a varnish based on the combination of polyimide resins used in the same proportions, and the present invention was completed.
すなわち本発明は、ポリアミドイミドと他のポリイミド
系樹脂を用いてなり、ポリアミドイミドの使用割合が全
ポリマ中の10〜50重量%であることを特徴とするワ
ニスを提供するものである。That is, the present invention provides a varnish that uses polyamide-imide and other polyimide-based resins, and is characterized in that the proportion of polyamide-imide used is 10 to 50% by weight based on the total polymer.
作用
前記した割合でポリアミドイミドを用いたポリイミド系
樹脂の併用系ワニスとすることにより、その理由は不明
であるが10〇−程度に厚塗りして焼付処理しても発泡
を生じない。Effect By using a varnish based on the combination of polyamide-imide and polyimide resin in the proportions described above, foaming does not occur even if the varnish is coated thickly to about 100% and baked, although the reason for this is unknown.
発明の構成要素の例示

イド等の場合には熱劣化の防止などに有用である。The varnish of the present invention can be preferably used for forming baked coating layers of various wire rods. Examples of such wires include iron-based control wires made of coated iron wires, optical fibers or image guides made of optical fibers bundled together, and various types of winding wires. The purpose of providing the baked layer may be arbitrary. For example, in the case of control wires, winding wires, etc., it is useful for preventing rust, preventing stranded wires from squeaking, and preventing oxidative deterioration in high-temperature atmospheres such as those around engines. It is also useful for preventing thermal deterioration in the case of optical fibers, image guides, etc.
