    摘要: A developer suitable for use with positive photoresists is based on a buffered aqueous-alkaline solution containing non-ionic surfactants and contains in the solution 1-100 ppm of the surfactants, preferably of the ethoxylated-alkylphenol type. The resultant photoresist shows outstanding properties with respect to the resolution and edge sharpness obtainable in the developed resist image and with respect to its developing activity, developing capacity and stability.

    摘要: The invention relates to the use of momodisperse, non-porous, spherical particles based on SiO.sub.2, TiO.sub.2, ZrO.sub.2, Al.sub.2 O.sub.3, V.sub.2 O.sub.5, Nb.sub.2 O.sub.5 or mixed systems thereof, which are optionally modified on the surface by covalently bonded organic groups, as fillers in organic matrix materials, the refractive index of the particles being adapted to the refractive index of the organic matrix according to the use.Polymeric or polymerizable systems which comprise these particles can be used, for example, as embedding compositions for optical, electro-optical and optoelectronic components. Such embedding compositions show an improved optical homogeneity. Light-emitting diodes produced with them are distinguished, inter alia, by an improved light yield.
