Abstract:
A highly crosslinked polysiloxane dye comprising at least 10 Si atoms, including at least one moiety of the formula (I) whose open Si-bonds each are linked to an oxygen atom and open O-bond is linked to a silicon atom in the rest of the polysiloxane, and wherein T is a direct bond or an organic spacer group such as C1-C18alkylene, C2-C12alkenylene, C5-C10cycloalkylene, C5-C10arylene, —C5-C10arylene-(C1-C10alkylene)- each of which may be end-capped towards the linkage to Dye by CO, COO, NR1, CONR1, NR1CONR1, CS, CSS, CSNR1, NR1CSNR1, O, S, SO, SO2, C5-C10cycloalkylene, C5-C10arylene; or T is C3-C18alkylene interrupted, and optionally end-capped towards the linkage to Dye, by CO, COO, NR1, CONR1, NR1CONR1, CS, CSS, CSNR1, NR1CSNR1, O, S, SO, —SO2—, C5-C10cycloalkylene, C5-C10arylene; or is CO; (CH2CH2—O)1-5; COO; N(R1); CON(R1); O; S; SO; SO2; R1 is hydrogen; unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl); and Dye is a residue of an organic dye, is useful for dyeing of organic materials, such as keratin-containing fibers, wool, leather, silk, cellulose or polyamides.
Abstract:
PROBLEM TO BE SOLVED: To provide a means which improves the dispersibility of a nanoparticle when dispersing the nanoparticles in a silicone resin which is used in a high-output light source such as a UV-LED. SOLUTION: The siloxane dispersing agent contains a head part having affinity with the nanoparticle and a tail part having affinity with the silicone resin. The nanoparticle paste composition contains the siloxane dispersion agent, the nanoparticles and the silicone resin. The nanoparticles are dispersed in the silicone resin using the siloxane dispersion agent which contains the head part having a nitrogen-containing group, a carboxyl group, a mercapto group or a phosphate group and the tail part having a silicone part and further a silicone resin having an epoxy resin is added thereto, and then the obtained mixture is thermally processed to form silicone rubber.

Abstract:
PROBLEM TO BE SOLVED: To provide a luminescent material which can emit a light from the blue region to the red region through the triplet MLCT(Metal-to-Ligand Charge-Transfer) and to provide an organic electroluminescence element using this. SOLUTION: A luminescent material emitting a phosphorescence is synthesized by bonding an organic metal complex to the side chain of a polysilsesquioxane. This luminescent material can be used when an organic film of an organic electroluminescence element is formed. This luminescent material emits a light in the wavelength range of 430-650 nm and is excellent in color purity and light emitting efficiency characteristics. COPYRIGHT: (C)2005,JPO&NCIPI
