  • Patent number: 8148042
    Abstract: A heat-sensitive imaging element includes an IR dye having a structure according to Formula I, wherein at least one of the Rd groups is a group which is transformed by a chemical reaction, induced by exposure to IR-radiation or heat, into a group which is a stronger electron-donor than the Rd; or wherein at least one of the Ra groups is a group which is transformed by a chemical reaction, induced by exposure to IR-radiation or heat, into a group which is a stronger electron-acceptor than the Ra. The imaging element is able to form a visible print-out image with a high contrast directly after image-wise exposure by IR-radiation or heating.

  • Publication number: 20100274023
    Abstract: The present invention provides new intermediate compounds enabling the preparation of N-meso substituted cyanine, merocyanine or oxonole dyes wherein the N-meso substituent comprises electron withdrawing groups and wherein such N-meso substituents are introduced at the intermediate level. These intermediates enable the formation of dyes having in the meso-position N-substituents comprising electron withdrawing groups without the need for further derivatization of the meso-substituent at the dye level.
