PURPOSE:To obtain an ultraviolet-shielding coating glass composition having low melting point, by adding TiO2, Fe2O3, Cr2O3, CeO2, V2O5, etc. to a matrix glass composed of P2O5, Al2O3, B2O3, F2, a component comprising CaO, ZnO, etc., and a component comprising Li2O, Na2O, etc. CONSTITUTION:The objective ultraviolet-shielding coating glass composition is produced by adding one or more components selected from 0.05-10.0mol of TiO2, 0.10-6.0mol of Fe2O3, 0.03-6.0mol of Cr2O3, 0.03-6.0mol of CeO2 and 0.001-0.5mol of V2O5 to 100mol of a matrix glass composed of 20-50(mol)% P2O5, 15-55% RO, 4-35% R2O, 0-20% Al2O3, 0-20% B2O3 and 0-18% F2 wherein RO is one or more compounds selected from CaO, ZnO, BaO, MgO and SrO, and R2O is one or more compounds selected from Li2O, Na2O, K2O and Cs2O.
