The present invention provides a thermal transfer receiving sheet obtained by sequentially forming a hollow particle-containing intermediate layer and an image receiving layer on one surface of a sheet-like support mainly comprising cellulose pulp, wherein the moisture content of the entire thermal transfer receiving sheet is from 2 to 8 mass % and the moisture permeability of the entire receiving sheet is 400 g/m&#xb7;day or less; and a production method thereof. The present invention further provides a thermal transfer receiving sheet obtained by sequentially forming a hollow particle-containing intermediate layer and an image receiving layer on one surface of a sheet-like support mainly comprising cellulose pulp and providing a backside layer on another surface of the support, wherein the backside layer mainly comprises an acryl-based resin having a glass transition point (Tg) of 45&#xb0; C. or less and contains a resin filler having an average particle diameter of 5 to 22 &#x3bc;m and the Bekk smoothness according to JIS P 8119 on the backside layer surface is 100 seconds or less.

Thermal transfer receiving sheet and its manufacturing method

A thermal transfer receiving sheet comprising a sheet-like support having sequentially formed on at least one surface thereof a hollow particle-containing intermediate layer and an image receiving layer, wherein the hollow particles have an average particle diameter of 0.2 to 35 &#x3bc;m and a hollow percentage by volume of 30 to 97% and the printing smoothness (Rp value) on the surface of the thermal transfer receiving sheet, as measured by using a Microtopograph under an applied pressure of 0.1 MPa 10 m-seconds after the initiation of pressure application, is 1.5 &#x3bc;m or less. A production method of the thermal transfer receiving sheet is also provided.

Thermal transfer receiving sheet, production method thereof and image forming method using the sheet

A thermal transfer receiving sheet having laminated, on one side of its support, an intermediate layer, a barrier layer and an image receiving layer in this order, wherein said intermediate layer comprises hollow particles, and said barrier layer comprises a polyvinyl alcohol derivative, and comprises, as further main components, a resin or a mixture of two or more resins selected from the group consisting of a styrene-maleic acid copolymer, a styrene-acrylic copolymer, an acrylic acid ester polymer and polyester, or wherein said barrier layer comprises, as main components, an ethylene vinyl alcohol copolymer and polyurethane.

Thermal transfer receiving sheet

There is provided a thermal transfer receiving sheet comprising a substrate, a barrier layer laminated on said substrate, and an image receiving layer laminated on said barrier layer, wherein said barrier layer and said image receiving layer are laminated on at least one side of said substrate, characterized in that the major components of said barrier layer are a swellable lamellar inorganic component and an adhesive, wherein said swellable lamellar inorganic component has a mean particle diameter of at least 0.1 &#x3bc;m and not greater than 100 &#x3bc;m, and an aspect ratio (ratio of mean particle diameter to thickness of the lamellar composite) of at least 100 and not greater than 5000.
