A method for manufacturing a thermal transfer image-receiving sheet support that can be used to obtain a thermal transfer image-receiving sheet that maintains its gloss and that has excellent handleability and high condition uniformity while preventing the formation of air bubbles in an adhesive layer. A resin is supplied to one side of a substrate, which is passed between a cooling roller A and a rubber roller A. A porous film is stacked on another side of the substrate through a resin, and the substrate is passed between a cooling roller B and a rubber roller B. The cooling rollers A and B have surfaces with a ten-point average roughness (Rz) of 5 to 30 &#x3bc;m and 0 to 20 &#x3bc;m, respectively. The rubber rollers A and B have a rubber hardness (durometer (Type A)) of 60 to 95 and 50 to 80, respectively.

Method for manufacturing thermal transfer image-receiving sheet support and method for manufacturing thermal transfer image-receiving sheet

Provided is a support for a thermal transfer image-receiving sheet, capable of obtaining a thermal transfer image-receiving sheet that has favorable stability against curl and is excellent in the texture of a print surface in the case of print under the environmental conditions of high temperature and high humidity. A support for a thermal transfer image-receiving sheet according to the present invention includes a porous layer composed of a porous film, a first polyolefin resin layer, a substrate layer, and a second polyolefin resin layer that are layered in the order mentioned, in which the first polyolefin resin layer has a density of 0.93 g/cmor less; and the second polyolefin resin layer has a density of more than 0.93 g/cm.

Support for thermal transfer image-receiving sheet, thermal transfer image-receiving sheet, and producing method therefor

Disclosed is a thermal transfer image-receiving sheet which excels in adhesiveness to a receiving layer and solvent resistance, and a manufacturing method thereof. In the thermal transfer image-receiving sheet, which includes a porous layer, a barrier layer, a receiving layer which are stacked in this order on a substrate, the porous layer includes a binder resin and hollow particles, and the barrier layer includes (i) (A) a first acrylic resin and (B) one or more kinds of resins selected from the group consisting of polyester resins, polyvinyl pyrrolidone type resins, polyester type urethane resin, and a second acrylic resin which differs from the first acrylic resin; or (ii) a polyvinyl pyrrolidone type resin.
