A shadow mask for a color picture tube a thermal includes insulating layer preventing heat transfer to an apertured shadow mask. The side of the mask directed toward the cathode of the color picture tube is coated with a heat-insulating layer including particles having a porous structure. The pores may contain heavy metals or heavy metal compounds so that electron reflection and absorption occurs directly within the layer. The resulting heat is transferred to the interior of the picture tube instead of to the mask.
