LUMINOUS OR FLUORESCENT ARTIFICIAL STONE COMPOSITILUMINOUS OR FLUORESCENT ARTIFICIAL STONE COMPOSITION ON

摘要

A noctilucent or fluorescent artificial stone composition wherein the resin content is at least 11 % by weight, a transparent inorganic fine grain component accounts for 0.3 to 1.0 W1, the W1 being the weight of a 10- to 70mesh inorganic fine grain component, and the weight (W2) of a 100-mesh-through inorganic fine grain component and the weight (W3) of a 100-mesh-through noctilucent or fluorescent component have the following relationship: W1 : (W2 + W3) = 1:2 to 5:1, and W2 : W3 = 1:2 to 5:1.
