Abstract
A thermal transfer image receiving sheet includes: a substrate made of paper; a polyolefin resin layer formed on a first surface of the substrate; an adhesive layer formed on a second surface of the substrate facing away from the first surface; a porous layer formed on the adhesive layer; a foundation layer formed on the porous layer; and an image receiving layer formed on the foundation layer. A surface of the substrate, as defined in JIS B 0601:2001, has a maximum valley (undulation) depth Wv of 2.00 μm or less and a root mean square slope for the waviness WΔq of 0.013 or less. The porous layer has a thickness of 25 μm or more, and a thickness of the polyolefin resin layer is 0.2 to 3.0 times the thickness of the porous layer.
