ABSTRACT:
The present invention provides a glass flake that is substantially free of boron trioxide (B2O3), barium oxide (BaO), zinc oxide (ZnO), and fluorine (F) and has sufficient heat resistance and good formability for glass flake. The glass flake of the present invention includes a glass composition that contains the following components, expressed in mol %; 50≦SiO2≦65; 4≦Al2O3<12; 5≦SrO≦25; 10<(MgO+SrO)≦30; 20≦(MgO+CaO+SrO)≦45; and 0<(Li2O+Na2O+K2O)<2; wherein the glass composition is substantially free of B2O3, BaO, ZnO, and F. This glass flake is useful for resin compositions, paints, cosmetics, ink compositions, and the like.
