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

A thermosensitive recording material for recording thereon clear colored images having an excellent storage persistency over a long time, comprises a thermosensitive colored image-forming layer formed on a substrate and comprising a colorless dye precursor, a binder and a color developing agent comprising at least one compound having at least one group of the formula (I): ##STR1## wherein R = unsubstituted aromatic group or substituted aromatic group having at least one substituent selected from alkyl, alkoxyl and halogen, and the thermosensitive colored image-forming layer further comprises an additive comprising at least one member selected from the compounds of the formulae (II) and (III): ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 = alkyl, alkoxyl, aralkyl, aryl, aryloxy, nitro, acetylamino, acetoacetylamino, halogen or hydrogen; and Ar.sub.1, Ar.sub.2 = unsubstituted phenyl or naphthyl or substituted phenyl or naphthyl with 1 to 3 substituent selected from aryl, alkyl, alkoxyl, nitro, alkylamino, allyloxy, aryloxy and aralkyloxy groups and halogen atoms, one of Ar.sub.1 and Ar.sub.2 having a substituent selected from alkoxyl, allyloxy, phenoxy and benzyloxy groups.

Thermosensitive recording material

A thermosensitive recording material capable of recording thereon clear colored images having high resistances to oily substances, plasticizers, moisture, and heat and an excellent storage persistency over a long time, comprises a thermosensitive colored image-forming layer formed on a sheet substrate and comprising a colorless dye precursor, a color developing agent, and a binder, the color developing agent comprising at least one compound of the formula (I): ##STR1## and the colored image-forming layer further comprising an additive comprising at least one selected from: (1) aromatic epoxy compounds, (2) aromatic aziridine compounds, (3) aromatic compounds of the formulae (II), (III) and (IV): ##STR2##
