A coated paper comprised of a paper substrate, at least one surface of which is provided with at least one coating layer, characterized in that the surface of said coating layer has cracks of a width of 0.2 to 3.0 &#x3bc;m and a length of 3 to 1000 &#x3bc;m in an amount of 1 to 1000 cracks per mmis provided. In another embodiment, a coated paper comprised of a paper substrate, at least one surface of which is provided with at least two coating layers, characterized in that an inner coating layer adjoining said paper substrate comprises a pigment having a crystal structure selected from the group consisting of acicular crystal, spindle-shape crystal, columnar crystal, and rice-shape granulated crystal, and starches, and an outermost coating layer formed on said inner coating layer comprises crack formation promoting particles and a styrene-butadiene copolymer having a glass transition temperature of 20 to 150&#xb0; C. is provided.

Coated paper

An image receiver material which, even when wound on a roll of a smaller diameter in a printer, an image receiver sheet is not peeled, such that the image receiver material is not susceptible to running troubles in a printer. To this end, there is provided a seal type image receiver material in which the image receiver material includes a separator including a release sheet base material and a release agent layer provided on its one surface and an image receiver sheet including a receiver sheet base material and an adhesive layer provided on its one surface. The separator and the image receiver sheet are layered together so that the separator and the image receiver sheet may be released from each other and so that the release agent layer of the separator faces the adhesive layer of the image receiver sheet. A half-cut is provided in the image receiver sheet. A stress relaxing portion is provided ahead of a half-cut provided in a direction subsequently perpendicular to the paper sheet feed/eject direction in the printer.

Image receiver material

A thermal transfer image recording composite sheet has a lamination structure: (2) image receiving sheet section (including image receiving layer (D), image recording sheet substrate (C) and adhesive layer (E)) and (1) release sheet section (including release layer (B) and release sheet substrate (A)), and exhibits, as a whole, a compressive modulus of 50 MPa or less, wherein, the substrate (C) is constituted from (a) an upper oriented porous polyester film layer bonded to the image receiving layer (D) and (b) a lower oriented porous polymer film layer, the polymer of which is different from polyester of the layer (a), laminated on the upper film layer (a) and bonded to the adhesive layer (E), or the adhesive layer (E) comprises, together with an adhesive agent, a plurality of hollow particles each formed from a hollow core portion and a shell portion and has an average particle size of 0.3 to 30 &#x3bc;m, in which recording sheet the image receiving section (2) can be separated from the release sheet section (1) and adhered to a desired article.

Thermal transfer image recording composite sheet

A thermal transfer recording sheet having a high resistance to denting due to the nipping pressure and/or thermal printing pressure has a substrate sheet including a core sheet and polyester films laminated on the two surfaces of the core sheet and an image receiving layer formed on a surface of the substrate sheet and containing a dyeable polymeric material, and exhibits a compression modulus of 50 MPa or less.
