摘要

Dye-containing layer of a film-forming polymeric binder and the application thereof in an information recording element. The invention relates to a dye-containing layer in which dye, if desired in a very large weight percentage is dissolved or finely divided in a copolymer (1:1) of methyl vinyl ether and maleic anhydride or a semi-ester thereof. The dye-containing layer is particularly suitable for use as a recording layer in an optical information recording element.
