摘要： The present invention relates to compositions comprising at least one oxonol dye and at least one metal complex of formula (I-1) or (I-2), to recording media comprising the compositions and to use of the compositions in the production of optical recording media, colour filters and printing inks, wherein the substituents are as defined in the description. Use of the metal complexes of formula (I) results, surprisingly, in a comparatively weak tendency of the oxonol dyes to aggregate in the solid state so that the absorption curve remains advantageously narrow even in the solid state, as a result of which recording media having high reflectivity as well as high sensitivity and good playback characteristics in the desired spectral range are made available.

摘要： The present invention relates to a photochromic ink, the process for its preparation which is based on a spiropyran powder obtainable by melting, cooling and crushing, and to a new form of a spiropyran obtainable thereby. Said process to prepare a photochromic ink comprises the steps of a) heating and melting the spiropyran at a temperature below 250 C, b) cooling the melt to obtain a solidified spiropyran, c) crushing the solidified spiropyran to obtain a powder, d) optionally adding the powder to a binder providing the basis for the photochromic ink.
