できる染料昇華方式の熱転写シートに関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a thermal transfer sheet used in a thermal transfer printer, and particularly to a dye sublimation type thermal transfer sheet that can use general-purpose plain paper as recording paper. .

設けられた特殊紙が一般に用いられている。Conventionally, a desired image, etc., has been recorded on recording paper via electrical signals using a thermal transfer sheet containing in its ink layer a dye that sublimes or vaporizes (hereinafter referred to as sublimable dye) by the heat of a thermal head or the like. A dye sublimation type (hereinafter referred to as a sublimation type) thermal transfer printer is known. Not just any kind of paper can be used as recording paper for this sublimation type thermal transfer printer.
As described in Japanese Patent No. 58-215398, special paper is provided with a resin layer (hereinafter referred to as a dyeing layer) made of polyester resin or the like that is easily dyed with a sublimable dye on a base paper. is commonly used.

題は解消されるが。If general-purpose plain paper, which is generally available on the market, is used as the recording paper without using such special paper, there are problems in that the density of the recording is low and the storage stability of the recording is insufficient. This problem can be solved by using a special recording paper provided with a dyed layer.
被記録紙が限定されて汎用性がなく、入手が面倒なばか
りか、価格が高いという欠点もある。It has disadvantages such as limited recording paper, lack of versatility, difficulty in obtaining it, and high price.
一方、この問題を解決する技術として、特開昭５９−１

た後、通常の熱転写記録を行う方法が提案されている。On the other hand, as a technique to solve this problem, Japanese Patent Laid-Open No. 59-1
．． As described in Japanese Patent No. 09393, a colorless or white heat-melt ink layer is provided on the substrate of a thermal transfer sheet, and after this heat-melt ink layer is transferred over the entire surface onto a recording paper, normal thermal transfer is performed. A method of recording has been proposed.

昇華型の記録では記録の保存性が充分でないという問題
がある。This method is an effective method because it enables thermal transfer recording even on recording paper with very low surface smoothness when recording using a heat-melting type thermal transfer sheet in which an ink layer that melts by heat is provided on a substrate. However, when a colorless or white heat-melting ink layer is used as a dyeing layer in sublimation thermal transfer recording,
During normal recording, the dyed layer melts due to heat, causing the recorded dots to smear or the melted dyed layer to adhere to the ink layer of the thermal transfer sheet, making it impossible to obtain high-quality recording. Also, if a heat-fusible substance is used as the dyeing layer,
Sublimation type recording has a problem in that it does not have sufficient storage stability.
本発明の目的は、被記録紙として汎用の普通紙を用いて
高画質な記録を行うことができる昇華型の熱転写シート
を提供することにある。An object of the present invention is to provide a sublimation type thermal transfer sheet that can perform high-quality recording using general-purpose plain paper as recording paper.

設けられている。The above object can be achieved by using a thermal transfer sheet having the structure shown in FIG. 1 and FIG. 3. In the figure, a thermal transfer sheet 1 is provided with an ink layer 7 containing a sublimable dye on a substrate 6, and adjacent to the ink layer, a dyeing layer 7 that can be thermally transferred onto the substrate is applied in the running direction of the thermal transfer sheet and in plane order. 8 is provided.

-Contains less than 10,000 polyester resins. Further, the softening temperature of this resin is preferably 80°C or higher and 150°C or lower. If it is less than 80°C, the storage stability of the thermal transfer sheet will be poor, and if it exceeds 150°C, the thermal transferability of the dyed layer will be poor.

転写記録用被記録紙と同等に高画質な画像が得られる。When such a polyester resin is provided as a dyeing layer,
When general-purpose plain paper is used as recording paper, the thermal transferability of this dyed layer to the recording paper is very good, and since this dyed layer is easily dyed with sublimation dyes, this dyeing layer is easily dyed with sublimation dyes. When sublimation type thermal transfer recording is carried out on a recording paper onto which a layer has been thermally transferred, an image of high quality equivalent to that of a normal sublimation type thermal transfer recording paper in which a dyed layer is previously provided on a base paper can be obtained.

and cyan ink surface 5, which has a heat-transferable dyeing layer between the surface 2
are arranged. The arrangement order of the yellow, magenta, and cyan ink surfaces is not particularly limited, and any arrangement order may be used. Further, a black ink surface may be added as necessary. In the case of monochrome recording, of course, it may be a negative color ink surface. The object of the present invention can be achieved if a surface having a thermally transferable dyed layer is arranged in front of a set of ink surfaces necessary for recording one sheet. The thermal transfer sheet 1 has a surface having this dyed layer and an ink surface as a set, and a large number of sets are formed in the same arrangement order.

ができる。In thermal transfer recording, first, a dyed layer is transferred onto recording paper (general-purpose plain paper) by heat from a thermal head or the like over the entire surface or only the portion necessary for recording. Next, by thermally transferring the sublimable dye in the ink layer of the thermal transfer sheet onto the recording paper to which this dyed layer has been thermally transferred, in the same manner as normal boundary wall type thermal transfer recording, high-quality recording can be obtained. . That is, by performing thermal transfer recording based on image signals in the order of yellow, magenta, and cyan in this example using heat from a thermal head or the like, a full-color image can be recorded on general-purpose plain paper.

Recording was performed using a thermal transfer printer having a thermal head having a large number of elements in a line (element density: 6 elements/nWn). The conditions for transferring the dyed layer onto the recording paper are the voltage applied to the thermal head7. OV, the current application time per line was 20 m5ec. At this time, the dyed layer of this example could be uniformly transferred from the thermal transfer sheet onto the recording paper. Next, thermal transfer was performed in the order of yellow, magenta, and cyan based on the image signal on the recording paper to which this dyed layer was transferred.

It has a high optical density, and according to this embodiment, even if general-purpose plain paper is used as the recording paper, a clear recording with high density can be obtained by thermally transferring the dyed layer onto the recording paper.

When thermal transfer recording was carried out in the same manner as in Example 2 except that Vylon 103) was used, a portion of about half the area of the dyed layer was not thermally transferred onto the recording paper and remained on the thermal transfer sheet substrate. As a result, the dyed layer could not be successfully thermally transferred onto the recording paper. Therefore, even if yellow, magenta, and cyan were thermally transferred onto the recording paper, as can be understood from Comparative Example 1, only a low-density record could be obtained in the areas where the dyed layer was not transferred.

エロー。<Example 3> In Example, a polyester resin (Kao Soap, ATR-2010) with a number average molecular weight of 7,400 and a softening temperature of 136°C was used as the resin for the dyed layer, and a South paper with a rough surface smoothness was used as the recording paper. Thermal transfer recording was carried out in exactly the same manner as in Example 1, except that bond paper 13C (Beck smoothness: approximately 5 seconds) manufactured by Wirth Co. (USA) was used. As a result, the dyed layer is uniformly thermally transferred onto the recording paper, and furthermore, it is colored yellow based on the image signal.

When thermal transfer recording was carried out in exactly the same manner as in Example 3, most of the dyed layer was not thermally transferred onto the recording paper and remained on the base of the thermal transfer sheet.
