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.
摘要:
The invention relates to the use of polyarylene sulphides (PAS), preferably polyphenylene sulphide (PPS) for the preparation of a structrual foam, a process for the production of this foam, and moldings obtainable by this process.

The present invention relates to new dihydrobenzothiazine compounds, to the production thereof and to the use thereof as stabilizers and co-stabilizers against the oxidative and/or thermal degradation of organic polymers.
摘要:
An extruded polycarbonate article suitable as an energy absorber is disclosed. The article includes a plurality of honeycomb chambers that are aligned substantially in the same direction, extend in the direction of the extrusion and are disposed adjacent to one another. A method of using the article entails aligning the honeycomb chambers in a direction parallel to the direction of the impact energy.

摘要:
The invention relates to two-component injection-molded articles in which polyarylene sulfides (PAS), preferably polyphenylene sulfide (PPS), are present as at least one component and to a process for their production.
