摘要： The present invention is to provide a thermal transfer image receiving sheet which is able to provide excellent printing sensitivity and prevent the generation of poor image quality in high density areas and folded lines even during high speed printing, and an image forming method for forming an image on the thermal transfer image receiving sheet. Presented is a thermal transfer image receiving sheet containing a substrate and, on at least one surface of the substrate, a composite porous layer containing a thermoplastic resin, and a dye receiving layer in this order from the substrate, wherein the composite porous layer contains a porous core layer and non-porous skin layers layered on both surfaces of the porous core layer; a total thickness of the non-porous skin layers is 5 to 15% of a whole thickness of the composite porous layer; and a density of the composite porous layer is 0.65 to 0.74 g/cm3.

摘要： In a seal-type thermal transfer image-receiving sheet, the total thickness thereof is 250 μm or less, a seal portion has a layered structure in which a pressure-adhesive layer, a seal portion substrate, and a receiving layer are layered in this order from a release portion side. A release portion has a layered structure in which a surface resin layer, a release portion paper substrate, and a back face resin layer are layered in this order from a seal portion side. One or both of the seal portion substrate and the surface resin layer includes a layer made of polyethylene terephthalate is 50 μm or more. The sum of the thickness of the seal portion substrate and the thickness of the surface resin layer is four times or more the thickness of the back face resin layer, and the thickness of the back face resin layer is 20 μm or more.

摘要： A thermal transfer sheet includes a substrate and a transfer layer, in which the transfer layer after transfer has a reduced peak height (Spk) of 0.6 μm or more. A method for producing a printed material using a thermal transfer sheet including a particle layer disposed on a substrate and an image-receiving sheet including a thermal protrusion-and/or-recess forming layer and a receiving layer stacked in that order on a second substrate, the receiving layer including an image that has been formed, includes the steps of heating the image-receiving sheet to form a protrusion and/or a recess at the image-receiving sheet, and heating the thermal transfer sheet to transfer the particle layer to at least part of the protrusion of the image-receiving sheet.

摘要： Provided is a seal-type thermal transfer image-receiving sheet capable of providing a seal section having novel designability. A seal-type thermal transfer image-receiving sheet includes a release section and a seal section integrated. The seal section is provided peelably from the release section. The seal section has a layered structure in which a pressure-adhesive layer and a receiving layer capable of receiving a sublimable dye are layered in the order mentioned from the side of the release section. When the seal section is peeled off from the release section, a reference plate and the seal section peeled off are superposed together, and a reflection density of the reference plate is measured from the side of the seal section, the value of the reflection density is 15% or more, on the presupposition that the reflection density of the reference plate before the superposition with the seal section is set to 100%.
