The invention concerns a stabilising composition, comprising: at least one antioxidant comprising one or more of: a phenolic antioxidant, a phosphite antioxidant, a sulphur-containing antioxidant, and an aminic antioxidant; and at least one buffering agent, wherein the buffering agent has the capacity to buffer in aqueous solution at a pH range from 4 to 8.

Post-consumer recycled polyethylene terephthalate (PCR-PET) flake is treated with chelant to reduce discoloration and generation of non-intentionally added substances (NIAS) upon melt-processing for use in making thermoplastic articles from the PCR-PET flake.

A light scattering sheet (light scattering body) is constituted of a molded resin body in which light scattering particles are distributed in a resin. The light scattering particles are particles of a phosphate of a rare earth element. The surface area of the light scattering particles per unit volume of the molded resin body is not greater than 0.600 m2/cm3. Preferably, the cumulative-volume particle diameter D50 of the light scattering particles with a cumulative volume of 50 vol %, obtained by using the laser diffraction/scattering particle-size-distribution measurement method, is 0.1-20 m. Also preferably, the value of D99/D50, which is the ratio of D99 to D50 of the light scattering particles, where D99 signifies the cumulative-volume particle diameter with a cumulative volume of 99 vol %, obtained by using the laser diffraction/scattering particle-size-distribution measurement method, is not greater than 10.

The invention relates to an optoelectronic component (100) comprising a semiconductor chip (1) configured for emitting radiation, a conversion element (2) comprising quantum dots (5) and configured for wavelength conversion of radiation, wherein the conversion element (2) comprises a layer structure (7) having a plurality of inorganic barrier layers (31, 32, 33, 34), wherein the inorganic barrier layers (31, 32, 33, 34) are spatially separated from one another at least regionally by a hybrid polymer (4), wherein the hybrid polymer (4) comprises organic and inorganic regions that are covalently bonded to one another, wherein the quantum dots (5) are embedded in the hybrid polymer (4) and/or at least in one of the barrier layers (31, 32, 33, 34).

Highly reliable interconnections for microelectronic packaging. In one embodiment, dielectric layers in a build-up interconnect have a gradation in glass transition temperature; and the later applied dielectric layers are laminated at temperatures lower than the glass transition temperatures of the earlier applied dielectric layers. In one embodiment, the glass transition temperatures of earlier applied dielectric films in a build-up interconnect are increased through a thermosetting process to exceed the temperature for laminating the later applied dielectric films. In one embodiment, a polyimide material is formed with embedded catalysts to promote cross-linking after a film of the polyimide material is laminated (e.g., through photo-chemical or thermal degradation of the encapsulant of the catalysts). In one embodiment, the solder resist opening walls have a wettable layer generated through laser assisted seeding so that there is no gap between the solder resist opening walls and no underfill in the solder resist opening.

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.
