Description

Detailed Description of the Invention [Technical Field] The present invention provides a method for easily and reliably removing erroneously recorded images when forming colored images using a color reaction between a leuco dye and a color developer. [Prior Art] Various heat-sensitive recording materials that utilize the color-forming reaction between a leuco dye and a color developer are known, but it is difficult to obtain a copy sheet that does not develop color in the background area by reheating. A leuco-based thermal recording material and a C1 thermal transfer medium have been developed. Regarding this thermal transfer medium, 1, for example, a thermal transfer sheet having a transfer layer containing a leuco dye as a main component,
A combination of a receptor sheet having a receptor layer containing a color developer as a main component, a transfer layer containing a leuco dye as a main component, and two types of transfer layers containing a color developer as a main component, respectively, either the same or separate. There is a combination of a heat-sensitive transfer sheet provided on a support and plain paper.

Such heat-sensitive recording materials are used in typewriters equipped with thermal heads, computer terminals, facsimile machines, etc., but erroneous recordings often occur and it is necessary to correct the recordings. To correct erroneous records,
Usually, methods such as scraping off the erroneous records with a sand eraser or applying white paint on the erroneous records are used, but these methods do not allow the above-mentioned color reaction between the leuco dye and the color developer to occur. In the case of the recording method used, it is impossible to record the correct record again because the color reaction is inhibited by the correction.

〔the purpose〕

An object of the present invention is to provide a member for correcting erroneous recording when recording is performed using the above-mentioned thermal transfer medium.

〔composition〕

According to the present invention, as a first invention, a thermal transfer medium comprising a transfer sheet having a transfer layer containing a leuco dye as a main component and a receiving sheet having a receiving layer containing a color developer as a main component is used. A member applied to correct erroneous recordings formed on the receiving sheet when thermal transfer is performed, and a colorant having a refractive index of 1.8 or more and having a similar color to the receiving layer of the receiving sheet, if necessary. A heat-sensitive transfer member for correction is provided, characterized in that a transfer layer containing a filler and a color developer having a reflectance of 60% or more is provided on a support. Further, according to the present invention, as a second invention, a transfer layer containing a leuco dye as a main component and a transfer layer containing a color developer as a main component are provided on the same or separate supports. A member for correcting erroneous recordings formed on the receiving sheet when thermal transfer is performed using a transfer medium consisting of a sheet and a receiving sheet such as plain paper. A thermal transfer member for correction is provided, characterized in that a transfer layer containing a colorant having a refractive index of 1.8 or more and, if necessary, a filler having a reflectance of 60% or more is provided on a support.

In the thermal transfer member for correction of the present invention, a colorant having a refractive index of 1.8 or more is used as a colorant for correction. In this case, the main purpose of the coloring agent is to coat the erroneous records formed on the receiving sheet with a coloring agent of the same color as the surface of the receiving sheet, making the erroneous records virtually unreadable by about 1 inch, and at the same time removing the corrected areas. The purpose is to make it less noticeable from the surface of the receiving sheet. In the first aspect of the present invention, a color developer similar to that contained in the receiving layer is used in combination so that when correct recording is performed after correction, the corrected area can be colored again.

The coloring agent used in the present invention includes complexions such as white, red, yellow, and green, and mixtures thereof, and typical examples thereof are shown in Table 1.

Colorants with a refractive index lower than 1.8 have weak hiding power, so they are ineffective in covering erroneous records unless they are used in large quantities, and the use of large quantities may reduce the thermal sensitivity of the correction thermal transfer member. lower.

Therefore, the use of a colorant with a refractive index of 1.8 or more is important in obtaining a corrective thermal transfer member with excellent hiding power and high thermal sensitivity. Furthermore, in the present invention, since each of the colorants described above can be used, even if the receiving cylinite is white or colored, by appropriately selecting the colorant or by appropriately blending the colorant, A corrective thermal transfer member having a color similar to that of the receiving sheet can be easily obtained.
