産業上の利用分野
本発明は多色あるいはフルカラー記録に用いられる感熱
転写記録装置の転写シートに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transfer sheet for a thermal transfer recording device used for multi-color or full-color recording.
従来の技術
従来この種の感熱転写記録装置は、例えば特開昭５８−
１４０２６７号公報に示されているように、第３図のよ
うな構成になっていた。2. Description of the Related Art Conventionally, this type of thermal transfer recording apparatus has been disclosed, for example, in Japanese Patent Application Laid-Open No. 1986-
As shown in Japanese Patent No. 140267, the configuration was as shown in FIG.
すなわち多色あるいはフルカラー記録を得る場合、信号
に応じて選択的に発熱されるサーマルヘッド２０と少く
ともイエロー２１ａ、マゼンタ２１ｂ、シアン２１ｃの
３色のインク層が順次形成された転写シート２１と被転
写紙２２を用い、転写シート２１の各インク毎に被転写
紙２２を往復させ、３色のインクを被転写紙２２上に重
ね合わせることにより多色あるいはフルカラー記録を行
っている。That is, when obtaining multi-color or full-color recording, a thermal head 20 that selectively generates heat according to a signal, a transfer sheet 21 on which ink layers of at least three colors of yellow 21a, magenta 21b, and cyan 21c are sequentially formed are used. Using a transfer paper 22, the transfer paper 22 is moved back and forth for each ink on the transfer sheet 21, and three color inks are superimposed on the transfer paper 22, thereby performing multicolor or full-color recording.
発明が解決しようとする問題点
一般に転写シート２１を用いる感熱記録方式では、被転
写紙の表面平滑度が重要で、平滑度が低い、すなわち被
転写紙の表面の凹凸が大きいとインクの転写不良が生じ
るため印字品質が悪くなり、カラー記録の場合、特にフ
ルカラー記録では重要な問題である。Problems to be Solved by the Invention Generally, in a thermal recording method using a transfer sheet 21, the surface smoothness of the transfer paper is important, and if the smoothness is low, that is, the surface of the transfer paper is highly uneven, the ink transfer will be poor. This results in poor print quality, which is an important problem in color recording, especially in full-color recording.
従って感熱転写記録の場合、モノクロ記録でも平滑度と
してペック平滑度で２００秒以上、多色記録では５００
秒以上の平滑度を有する複転写紙が推奨されている。Therefore, in the case of thermal transfer recording, even monochrome recording has a Peck smoothness of 200 seconds or more, and multicolor recording has a smoothness of 500 seconds or more.
A duplex transfer paper with a smoothness of 2 seconds or better is recommended.
しかし最近葉書や複写機用の紙などの一般被転紙へのカ
ラー記録が望まれているが、平滑度が１００〜２００秒
と低いだめ品質の良い記録ができないという問題があっ
た。However, recently there has been a desire for color recording on general paper to be transferred, such as postcards and paper for copying machines, but there has been a problem that high-quality recording cannot be achieved because the smoothness is as low as 100 to 200 seconds.
つまり、複写機用の上質紙で平滑度が１５０秒程鹿の場
合、表面の凹部（転写シート側から見て）が２０μｍ程
あり、サーマルヘッドで加熱しても凹部の表面温度は４
０’Ｃ以下と言われており（第２回ノンインパクトプリ
ンティング技術シ／ポジウム論文集、８５）、このよう
な温度では転写温度が６０〜７０°Ｃと低い溶融性顔料
を使用した場合でも被転写紙に転写されないことになる
。In other words, in the case of high-quality copying machine paper with a smoothness of about 150 seconds, the recesses on the surface (viewed from the transfer sheet side) are about 20 μm, and even when heated with a thermal head, the surface temperature of the recesses is 4.
It is said to be below 0'C (2nd Non-Impact Printing Technology Symposium Proceedings, 85), and at such temperatures even when using melting pigments whose transfer temperature is as low as 60-70°C, they will not be exposed to heat. It will not be transferred to the transfer paper.
そこで、本発明は葉書をはじめ平滑度が２００秒以下の
被転写紙にも品質の良い多色あるいはフルカラー記録が
行える転写シートを提供するものそして上記問題点を解
決する本発明の手段は、上記転写シートに３色のインク
層とは別に転写安定化層を３色毎の先頭に形成するもの
である。Therefore, the present invention provides a transfer sheet that can perform high-quality multi-color or full-color recording even on paper having a smoothness of 200 seconds or less, including postcards. In addition to the ink layers of the three colors, a transfer stabilizing layer is formed on the transfer sheet at the beginning of each of the three colors.
作 用 この手段による作用は次のようになる。For production The effect of this means is as follows.
すなわち、３色のインク層を被転写紙上に重ね合せる前
に転写安定化層を被転写紙上に転写し、被転写紙表面の
凹凸を目塗めした後、３色のインク層を重ねることによ
シ印字品質のよいカラー記録が行えるようになるのであ
る。In other words, before overlapping the three color ink layers on the transfer paper, a transfer stabilization layer is transferred onto the transfer paper, and after the unevenness of the transfer paper surface is covered, the three color ink layers are overlaid. This makes it possible to perform color recording with better print quality.
実施例
以下、本発明の実施例を添付図面にもとづいて説明する
。第１図、第２図において、１は転写ジートチ、ベース
シート２上に少くともイエロー４ａ、゛マゼンタ４ｂ、
シアン４ｃの３色からなるインク層４と、３色毎のイン
ク層４の前に転写安定化層３が形成されている。Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 1 is a transfer sheet, and at least yellow 4a, magenta 4b,
An ink layer 4 consisting of three colors, cyan 4c, and a transfer stabilizing layer 3 are formed in front of the ink layer 4 for each of the three colors.
この転写安定化層３は、例えばインク層４が溶融性顔料
タイプのものであれば、顔料とのバインダと同じワック
ス系のもの、あるいは顔料との親和性のよい樹脂を混合
したワックスなどで構成されている。For example, if the ink layer 4 is of a meltable pigment type, the transfer stabilizing layer 3 is made of the same wax-based binder as the pigment, or a wax mixed with a resin that has good affinity with the pigment. has been done.
また印字品質のよい記録を望む場合、転写安定化層３は
少くとも被転写紙の表面凹部深さに相当する厚みが必要
で、複写機用の上質紙に対しては１０μｍ以上の転写安
定化層の厚みが望まれる。In addition, if you want to record with good print quality, the transfer stabilization layer 3 needs to have a thickness equivalent to at least the depth of the surface recesses of the transfer paper, and for high-quality paper for copying machines, the transfer stabilization layer 3 should have a thickness of 10 μm or more. Layer thickness is desired.
次に、この実施例の構成における作用を説明する。Next, the operation of the configuration of this embodiment will be explained.
記録開始信号が入力されると、先ず転写シート１の転写
安定化層３の部分がサーマルヘッドとの所定の位置関係
におかれ、被転写紙と重なった状態でサーマルヘッドの
熱を受け、被転写紙表面くとも印字範囲内全域に転写安
定化層３が転写される。When a recording start signal is input, first, the transfer stabilizing layer 3 portion of the transfer sheet 1 is placed in a predetermined positional relationship with the thermal head, receives heat from the thermal head while overlapping the paper to be transferred, and absorbs heat from the thermal head. The transfer stabilizing layer 3 is transferred to at least the entire printing area on the surface of the transfer paper.
この際インク層４に比べ、転写安定化層３の方が流動性
が良いため被転写紙の表面凹部の目塗めかされる。従っ
て被転写紙として平滑度が高まるとともに、インク層４
のバインダと同じワックスを用いれば各インク層４との
密着性も良好となる。At this time, since the transfer stabilizing layer 3 has better fluidity than the ink layer 4, the concave portions of the surface of the transfer paper are painted. Therefore, the smoothness of the transfer paper increases, and the ink layer 4
If the same wax as the binder is used, the adhesion to each ink layer 4 will also be good.

カラー記録が行える。Next, the transfer paper to which the transfer stabilization layer 3 has been transferred returns to the initial position, and the yellow 4a of the transfer sheet 1 is cued up, and the yellow 4a ink is applied to the transfer stabilization layer on the transfer paper according to the data signal. Transferred onto 3. Thereafter, by repeating the same operation 9 times for magenta 4b and cyan 4c, it is possible to perform color recording with good print quality on transfer paper with low surface smoothness.

ものである。Effects of the Invention The present invention uses a transfer sheet in which ink layers of at least three colors of yellow, magenta, and cyan and a transfer stabilizing layer are repeatedly formed at the top of each of the three colors in color thermal transfer recording. By first transferring the transfer stabilizing layer onto the transfer paper and coating the concave areas on the surface of the transfer paper, it can be used even on transfer papers with low smoothness such as postcards or paper for copying machines. It is capable of recording in color or full color.
