Abstract
An artificial marble formed by molding a material, in which said material comprises an unsaturated polyester, an unsaturated polymerizable monomer, and a filler. The unsaturated polyester consists essentially of an acid component and an alcohol component, wherein said alcohol component contains at least a glycol selected from a group consisting of 2-methylpropane-1,3-diol, 3-methylpentane-1,5-diol, 3-methyl-2-pentene-1,5-diol, 2-isopropylidene-1,3-propanediol, 2-isopropyl-1,3-propanediol, and 2-methylene-1,3-propanediol.
Claims4
