Abstract: An image recording sheet for thermotransfer printing has an image recording layer that contains a dried polymer latex with a minimal film-building temperature of up to 80 DEG C. The polymer is composed of: (I) 40 to 70 wt % vinyl halogenide; 30 to 60 wt % at least one ester of acrylic or methacrylic acid with alcohols having 1 to 24 C atoms; and 0 to 20 wt % at least another copolymerizable, non cationic monomer; or (II) 80 to 100 wt % at least one ester of acrylic or methacrylic acid with alcohols having 1 to 24 C atoms; and 0 to 20 wt % at least another copolymerizable, non cationic monomer; or (III) 8 to 70 wt % at least one nitrogen-free vinyl aromatic compound and/or one ethylenically insatured nitrile having 3 to 6 C atoms; 30 to 92 wt % at least one ester of acrylic or methacrylic acid with alcohols that contain 1 to 24 C atoms; and 0 to 20 wt % of at least another copolymerizable, non cationic monomer; or (IV) 30 to 95 wt % vinyl ester of carbon acids that contain 1 to 20 C atoms; 5 to 70 % at least one ester of acrylic or methacrylic acid with alcohols that contain 1 to 24 C atoms; 0 to 15 wt % an ethylenically insatured nitril with 3 to 6 C atoms; and 0 to 10 wt % at least another copolymerizable, non cationic monomer. Also disclosed are the preparation and use of the polymer latex in reproduction processes and for producing information systems.
