    摘要: The present invention provides free-flowing chemically resistant color granulates that are heat resistant and color stable in aggressive media. The color granulates comprise 20-94.8% by weight coloring bodies, 5-75% by weight of one or more frits, 0.220% by weight binder and 0.03-15% by weight organosilanes and/or polyorganosiloxanes. The glass frit comprises by weight 20-90% SiO.sub.2 +B.sub.2 O.sub.3 +Al.sub.2 O.sub.3, 0-6% Na.sub.2 O+Li.sub.2 O, 0-6% K.sub.2 O, 10-25% CaO+MgO+ SrO, 0-35% TiO.sub.2 +ZrO.sub.2, 0-40% Bi.sub.2 O.sub.3 +P.sub.2 O.sub.5 +V.sub.2 O.sub.5 +MoO.sub.3 +WO.sub.3 and 0-10% ZnO.
