    Abstract: The invention concerns an image-recording sheet for use in thermal-transfer printing, the sheet including an image-recording layer containing a dried latex of a polymer with a minimum film-forming temperature less than or equal to 80 DEG C, the polymer containing 0.4 to 35 % by wt. of at least one self-cross-linking monomer, which is not butadiene, polymerized into it. The invention also concerns the production of this polymer latex, and its use in reproduction processes and in the production of information systems.
