定。Conventionally, in order to obtain a thermal transfer medium with excellent scratch resistance and storage stability, which does not cause image loss or staining even when mechanical force is applied to the recorded image, the ink layer was prepared using a 2.4-trirange film. A mixture of an isocyanate compound such as an isocyanate binaric compound and a polyol such as a diol or triol having a melting point of 60 to 120°C has been proposed (see Japanese Patent Publication No. 61-14956). However, during long-term storage or high-temperature environments (albeit for a short time during transportation),
The reaction between the isocyanate and the polyol progresses at temperatures as high as 60° C.), resulting in deterioration of printing performance and the inability to perform thermal transfer. Therefore, the period from the time a thermal transfer recording medium is manufactured to the time it is used is limited.
あるいは保存環境の限定等の制約が付加され、取扱いが
不便で、使用し難いものとなってしまう恐れがあった。Alternatively, restrictions such as limitations on the storage environment may be added, making the product inconvenient to handle and difficult to use.
このように従来のものは使用前の保存安定性に欠けるも
のであった。As described above, conventional products lacked storage stability before use.
また、これらの制約を緩和するためには、反応性の劣る
イソシアネートを用いなければならず、記録時の印加エ
ネルギーだけでは反応を進行できず、加熱処理の工程を
付加する等の煩雑さが増す欠点があった。In addition, in order to alleviate these constraints, it is necessary to use isocyanates with poor reactivity, and the reaction cannot proceed with just the energy applied during recording, which increases the complexity of adding heat treatment steps. There were drawbacks.

媒体を提供することを目的とする。The present invention overcomes the conventional drawbacks and can record on various recording media such as plain paper and film using a thermal head, has excellent abrasion resistance, and even if mechanical force is applied to the recorded image, it will not cause image loss or stains. It is an object of the present invention to provide a heat-sensitive transfer recording medium that can obtain records with good storage stability without causing any problems, and also has excellent storage stability before use.

、本発明を完成した。As a result of intensive studies to achieve the above object, the present inventors have found that by separating isocyanate and polyol through an intermediate layer and forming each layer as separate and independent layers, it is possible to solve the conventional drawbacks and improve recording performance. It was found that image performance was also superior to conventional mixed-layer systems, and the present invention was completed.

無機顔料、有機顔料又は染料の中から適当なものを選択
して用いることができる。As a coloring agent, commonly used carbon black,
An appropriate pigment can be selected from among inorganic pigments, organic pigments, and dyes.
添加量も目的の濃度に応じて任意の斌を添加できるが、
あまり多量に添加すると層の構造強度を低下させるので
注意しなければならない。例えばカーボンブラックの場
合、添加量が３０重量％を越えると強度が急激に低下す
ることがあるので、添加量を３０重量％以下にする必要
がある。Any amount can be added depending on the desired concentration, but
Care must be taken because adding too much will reduce the structural strength of the layer. For example, in the case of carbon black, if the amount added exceeds 30% by weight, the strength may drop sharply, so the amount added must be 30% by weight or less.
