    摘要: A process for the optical recording and storage of information in the form of bits by irradiating a recording material comprising a substrate coated with at least one layer of a pigment selected from the group of the dithiopyrrolopyrroles, dithioquinacridones, phthalocyanines or mixtures of several of these pigments as recording layer dotwise or linearly with laser light in the near infrared range (NIR range), which pigment (a) has a crystal modification having an absorption band in the NIR range, and (b) is in contact with a solid organic compound that changes the crystal modification of the pigment upon irradiation with laser light, so that (c) after irradiation the absorption in the NIR range is reduced, while the organic compound exhibits no absorption in the NIR range before and after irradiation.
