Abstract
The present invention relates to glass fibers, especially for reinforcing organic materials and having an alumino-silicate glass composition, containing one or more alkaline earth metal compounds and with a low content of alkali metal compounds, wherein the composition further contains a combination of coloring agents formed from iron oxides, cobalt oxide and, optionally, chromium oxide, which enable the fibers to be dyed in bulk and to have more neutral tones.
