Abstract
Cross-liked resins exhibiting a high level of optical transparency and little variation of refractive index with temperature are prepared using mixtures of two organosiloxane resins in combination with a reinforcing silica filler. The types and relative concentrations of hydrocarbon radicals in the resins are within specified limits to obtain the required optical properties and each resin contains groups that react with groups on the other resin to form a crosslinked network.
