Embodiment 1

[0064] [Formation of interlayer-coated sheet]

[0065]70 parts of aqueous dispersion (solid concentration: 30%) of expanded hollow particles (average particle size: 5.4 µm, void percentage: 60%) containing thermoplastic resin mainly composed of 1,1-dichloroethylene and acrylonitrile were mixed and stirred , 15 parts of polyvinyl alcohol (trade name: PVA217, Kuraray Co., Ltd.) aqueous solution (solid concentration: 10%) and 15 parts of styrene-butadiene latex (trade name: L-1537, solid concentration: 50 %, Asahi Kasei), thereby preparing an intermediate layer coating solution. It was then coated and dried on a coated paper sheet (trade name: OKKinfuji-N, paper basis weight: 186 g / m2, Oji Paper Co. Ltd.) as a base to 20 g using a die coater. dry coverage per square meter to form a sheet coated with an intermediate layer.

[0066] [Formation of sheet coated with impervious layer]

[0067] 100 parts of polyvinyl alcohol (trade name: PVA105, degree of polymerization: about 500, ...

Embodiment 2

[0073] A receiving sheet was prepared in the same manner as in Example 1, but using an expanded hollow particle containing a thermoplastic resin mainly composed of 1,1-dichloroethylene and acrylonitrile, but having a different particle diameter (average particle diameter: 1.6 µm) , Void percentage: 50%) aqueous dispersion (solid concentration: 30%) was used to replace the thermoplastic compound mainly composed of 1,1-dichloroethylene and acrylonitrile used to form the interlayer-coated sheet of Example 1. Expanded hollow particles of resin (average particle diameter: 5.4 µm).

Embodiment 3

[0075] A receiving sheet was prepared in the same manner as in Example 1, but using an expanded hollow particle containing a thermoplastic resin mainly composed of 1,1-dichloroethylene and acrylonitrile, but having a different particle diameter (average particle diameter: 18.1 µm) , Void percentage: 65%) aqueous dispersion (solid concentration: 30%) was used to replace the thermoplastic compound mainly composed of 1,1-dichloroethylene and acrylonitrile used to form the interlayer-coated sheet of Example 1. Expanded hollow particles of resin (average particle diameter: 5.4 µm).

Abstract

A thermal transfer receiving sheet comprising a barrier layer and an image-receiving layer sequentially disposed on at least one surface of a supporting body is disclosed. The barrier layer mainly contains a swellable inorganic lamellar compound and an adhesive. The swellable inorganic lamellar compound has a mean particle length of 0.1-100 mum and an aspect ratio (ratio of mean particle length to thickness) of 100-5,000.

Description

field of invention [0001] This invention relates to thermal transfer-receiving sheets. More specifically, the present invention relates to a thermal transfer receiver sheet (hereinafter also simply referred to as "receiver sheet") having high image quality and high image stability, which also has excellent curl resistance during printing and is not expensive. Background technique [0002] In recent years, thermal printers, especially dye thermal transfer printers that can print clear full-color images, have attracted more and more attention. Dye thermal transfer printers form an image by placing the dye-containing layer of an ink plate on an image-receiving layer (hereinafter also simply referred to as "receiving layer", which contains a dye-fixable resin on a receiving sheet), and then A thermal head or the like supplies heat to transfer the dye at a predetermined position of the dye layer of the ink plate onto the receiving layer. Ink plates contain three-color dye laye...
