Embodiment 1

[0173] 2.06 parts of dyes with the following structure

[0174]

[0175] Suspended in 45 parts of completely demineralized water. Use a high-performance disperser (such as Ika ) 50 parts of polydimethylsiloxane with amino groups (amine value: 92 micromole amine groups per gram; viscosity: 300 mm2 / s) were processed for 3 minutes, thereby heated to about 30° C., and then The aqueous dye solution was uniformly dispersed in the silicone using a high performance disperser for 10 minutes, during which time the reaction mixture was heated to about 60°C. The remaining water was removed under reduced pressure and after cooling to room temperature the product was filtered through a depth filter. 100 parts of yellow silicone oil can be obtained.

Embodiment 2

[0177] A mixture of 4.52 parts of three dyes with the following structure

[0178]

[0179] Suspended in 9 parts of completely demineralized water. With a high-performance disperser (such as Ika ) 100 parts of polydimethylsiloxane with amino groups (amine value: 92 micromole amine groups per gram; viscosity: 300 mm2 / s) were processed for 3 minutes, thereby heated to about 30° C., and then The aqueous dye solution was uniformly dispersed in the silicone using a high performance disperser for 10 minutes, during which time the reaction mixture was heated to about 60°C. The remaining water was removed under reduced pressure and after cooling to room temperature the product was filtered through a depth filter. 99 parts of black silicone oil can be obtained.

Embodiment 3

[0181] 7.37 parts of the dye mixture described in Example 2 were suspended in 15 parts of completely demineralized water. Use a high-performance disperser (such as Ika ) 50 parts of polydimethylsiloxane with amino groups (amine value: 300 micromole amine groups per gram; viscosity: 301 mm2 / s) were processed for 3 minutes, thereby heated to about 30° C., and then The aqueous dye solution was uniformly dispersed in the silicone using a high performance disperser for 10 minutes, during which time the reaction mixture was heated to about 60°C. The remaining water was removed under reduced pressure and after cooling to room temperature the product was filtered through a depth filter. You can get 100 parts of black silicone oil.

Abstract

The present invention relates to colored organopolysiloxanes containing units of the general formula (I) in which R, R, R, A, a, b, c and d are each defined as specified in claim 1, to processes for their preparation and to their use.

Description

technical field [0001] The present invention relates to functionalized organosilicon compounds to which additional chromophore molecules are covalently bonded, to processes for their manufacture, and to the use of these colored organosilicon compounds. Background technique [0002] The simultaneous use of silicon compounds and dyes can be problematic due to the immiscibility or immiscibility of most dyes in silicon compounds. Therefore, lack of compatibility between the two substances often results in an unevenly colored product and / or slow exudation of one of the product components, thus resulting in overall poor product performance. For example, the use of defined physical blends of dyes with specific silanes and / or siloxanes, as disclosed in U.S. Patent No. 5,281,240, can somewhat reverse these adverse results, but does not prevent separation of the individual components in the long term . [0003] Instead, if the dye molecules are chemically bonded to the organosilicon...
