The glass transmittance of UV light having a wavelength of 365 nanometers is reduced by compounding an oxide or salt of at least one of Fe, Cu, Cr, Ce, Mn and mixtures thereof. The fiberglass cloth can be used for providing reinforced prepregs used in producing printed circuit boards or laminated chip carrier substrates.
