    摘要: A storage medium for optical data recording comprises a dye-forming combination which on exposure to light within a first range of wavelengths reacts irreversibly to form a dye, but is substantially insensitive to light within a second range of wavelengths which is capable of energizing the dye to produce luminescence. The dye-forming combination consists of a heterocyclic compound of the formula I and of a cyclic dihalodicarbonyl compound of the formula II ##STR1## The symbols are defined in the specification. An example of formula I is benzofuran and an example of formula II is dibromomaleic anhydride.
