Problems solved by technology

[0008] However, the surface roughness values ​​obtained using existing measurement methods do not necessarily correlate sufficiently with the image quality of actual dye thermal transfer printers
Especially in the case of printing with existing high-speed, low printing pressure printers, it is difficult to achieve good image quality
[0009] In addition, in the above example, a very satisfactory gloss cannot be obtained.
The middle layer containing hollow particles has good cushioning, but the surface of the printing layer is easily damaged. Partial micro-scratches, uneven gloss, and lower product value in appearance

Abstract

There is provided a thermal transfer reception sheet having at least one side of sheet-shaped support body on which an intermediate layer having hollow particles and an image reception layer are successively formed. The hollow particles have an average particle diameter of 0.2 to 30 [mu]m, and volume hollow ratio of 40 to 95%. Furthermore, the printing smoothness (Rp value) measured after 10 m sec after start of pressurizing the image reception layer surface with a pressure of 0.1 MPa by using the micro-topography is not greater than 1.5 [mu]m. The 20-degree gloss based on JIS Z 8741 is 80 or below.

Description

technical field [0001] The present invention relates to a thermal transfer printing sheet (hereinafter referred to as "printing sheet" for short) that is laminated with a thermal transfer printing sheet (ribbon) and thermally transfers the dye of the ribbon to form an image by using a thermal head. ). More specifically, the present invention relates to a printing sheet having an intermediate layer containing hollow particles between a sheet-shaped support and an image printing layer, which is particularly suitable for dye thermal transfer printers. Background technique [0002] In recent years, thermal printers have attracted attention, especially dye thermal transfer printers that can print vivid full-color images. The dye thermal transfer printer is to laminate the dye layer containing the dye of the ribbon with the image printing layer (hereinafter sometimes referred to as the "printing layer") of the printing sheet containing the dye affinity resin, and use a thermal he...
