Translation of "Licht absorbierende" in English

In this case, the light-absorbing potting material can be transparent.

By way of example, both the housing body and the light-absorbing material may be black.

By way of example, the light-absorbing material is black.

Materials that are transparent to light or that absorb light can also be used as backing materials.

The sand, which absorbs the light, forms a contrast to the silver reflections of the aluminum.

In this case, the light-absorbing material can be applied in a targeted manner where it covers a connection region.

The light-absorbing material may comprise, for example, carbon black and/or color pigments and/or CNT.

By way of example, the light-absorbing material, at side areas of the radiation-emitting semiconductor chip, can directly adjoin the latter.

Preferably, light-absorbing material is introduced into the polymer material of at least some of the yarns.

Materials that absorb light are also suitable for obtaining electrical energy from irradiated light energy.

The top material would absorb the water and carbon dioxide from the air, and the next, light-absorbing layer would harness the sun’s energy to produce the fuel.

Light absorbing test materials may give rise to a growth rate reduction because shading reduces the amount of available light.

Substances which absorb ultraviolet light, for example benzophenone derivatives or benzotriazole derivatives, such as 2-(2-hydroxy-5-methylphenyl)-benzotriazole or 2-(2'-hydroxy-3'-tert.-butyl-5'-methylphenyl)-5-chloro-benzotriazole, can be added in an amount of 0.05 to 2% by weight, relative to the total weight of the molding composition, in order to improve the stability to light.

The light-absorbing compound is present in the form of a dye salt of at least one benzothiazole which is converted into its leuco base under the action of an alkaline medium.

The diazotype material described in German Pat. No. 1,263,505 comprises a single layer which contains the diazonium salt, the coupler component and, in addition, an ultraviolet absorbing compound which effectively absorbs radiation in the spectral region from 300 to 460 nm and is changed by actinic radiation in such a way that it is no longer capable of absorbing radiation in this spectral region.

German Pat. No. 2,035,392 (corresponding to U.S. Pat. No. 3,679,415) discloses a diazotype material for the reproduction of continuous tone originals which contains, as the ultraviolet absorbing compound, a specific pyrylium or thiapyrylium salt, which is completely bleachable in an alkaline medium. The disclosed diazotype material has an extended exposure latitude and shows hardly any staining in the highlight image areas.

In accomplishing these objects, there has been provided according to the present invention a two-component diazotype material in which the light-absorbing compound is present in the form of a dye salt of at least one benzothiazole which is converted into its leuco base by the action of an alkaline medium, and thus partially or completely loses its absorptivity towards radiation in the long-wave ultraviolet and short-wave visible spectral regions.

If several light-sensitive layers are used, the light-absorbing compound is preferably contained in the last-irradiated light-sensitive layer.

The most preferred light-absorbing compounds are 6-methyl-2(4'-aminophenyl)-benzothiazole, which is commercially available under the name of DEHYDROTHIOTOLUIDINE, and 6-methyl-2(4'-benzylaminophenyl)-benzothiazole.

For improving the light stability substances absorbing the UV light, for example, benzophenone or benztriazole derivatives, for example, 2-(2'-hydroxy-5' methylphenyl)-benztriazole or 2-(hydroxy-3'-tertiarybutyl-5'-methylphenyl)-5-chloro-benztriazole may be added to the mixtures.

The light-absorbing compound comprises a benzothiazole, in particular according to the general formula: ##STR1## wherein R1 denotes hydrogen, alkyl or aralkyl,
