Abstract:
A luminous or fluorescent artificial stone composition comprising a fine powder component of an inorganic material having a size of from 5 to 70 mesh, a finely divided component of an inorganic material having a size of 100 mesh-under, a luminous or fluorescent component of 100 mesh-under having a luminescence or a luminousness accompanied by ultraviolet absorption, and a resin component, whereinthe sum of the weights of said fine powder component of the inorganic material, finely divided component of the inorganic material and luminous or fluorescent component is 89% by weight or more based on the total artificial stone composition, the weight of said resin component is 11% by weight or less based on the total artificial stone composition,a ratio of from 30 to 100% of the weight (W.sub.1) of said fine powder component of the inorganic material is a fine powder component of a transparent inorganic material,the ratio of the weight (W.sub.1) of said fine powder component of the inorganic material to the sum (W.sub.2 +W.sub.3) of the weight (W.sub.2) of said finely divided component of the inorganic material and the weight (W.sub.3) of said luminous or fluorescent component isW.sub.1 :(W.sub.2 +W.sub.3)=1:2 to 5:1,andthe ratio of the weight (W.sub.2) of said finely divided component of the inorganic material to the weight (W.sub.2) of said luminous or fluorescent component isW.sub.2 :W.sub.3 =1:2 to 10:1.
