    Abstract: An aromatic polycarbonate having high durability and excellent in color tone, transparency, and mechanical strength, especially one having high durability and stability in long-term use under high-temperature high-humidity conditions; a process for producing the polycarbonate; and a use thereof. The aromatic polycarbonate has a sodium content of 100 ppb or lower and nickel, lead, chromium, manganese, and iron contents of 70 ppb or lower each. The process for producing the aromatic polycarbonate comprises condensation-polymerizing an aromatic dihydroxy compound and a carbonic diester. The starting materials each has been regulated so that (1) the sodium content therein is 52 ppb or lower and (2) the concentrations of iron, chromium, manganese, nickel, and lead therein each is 40 ppb or lower. For the polymerization, (3) a specific catalyst is used in a specific amount based on the iron contained in the starting materials.

    Abstract: High sensitive organic dye-in-polymer (DIP) medium for write-once-read-many (WORM) optical discs with fluorescent reading. The medium consists of a fluorescent color means, capable of absorbing writing radiation produced by a laser, a compound capable of generating free radicals upon influence of heat produced by the writing radiation and a polymer capable of producing a translucent film enabling high quantum yield of the fluorescence induced in the color means. The color means can be selected from xanthene dyes of the eosine and rhodamine groups, acridine, oxazine, azine, peylene, violanthrone, cyanine, phtalocyanine, indigoide colors and porphyries. The free radicals generating compound can be chosen from the group of compounds comprising azo and diazoi compounds or peroxyde compounds. The film producing polymer can be selected from the group of compounds comprising cellulose ethers, vinyl resins or acrylic resins.
