Thermal transfer sheet and method for producing printed material

A combination of a thermal transfer sheet and an image-receiving sheet, wherein

• the thermal transfer sheet includes a first substrate and a particle layer disposed on a surface of the first substrate, the particle layer contains visible light-nonabsorbing particles,
• the image-receiving sheet includes a second substrate, a thermal recess-forming layer disposed on the second substrate, and a receiving layer disposed on the thermal recess-forming layer, and the thermal recess-forming layer includes at least one of a porous film and a hollow particle-containing layer,
• wherein, during transfer to the image-receiving sheet, the particle layer is peeled off from the first substrate at an interface between the first substrate and the particle layer and transferred to the image-receiving sheet, and
• wherein, after the transfer, the particle layer has a reduced peak height (Spk) of 0.6 μm or more.
