A method in which a liquid resin in which a coloring agent is dispersed non-uniformly is injected into a molding cell, one or more liquid resins having different colors are laminated to form one or more layers on the liquid resin in which a coloring agent is dispersed non-uniformly, a comb-like tool is allowed to move through the laminated liquid resins while allowing the teeth to contact the bottom surface of the molding cell, and then, liquid resins are cured to produce artificial marble having stripe pattern. Artificial marble having a radial cut moire pattern with a delicate hue of wood and a natural appearance, or a stripe pattern having a natural marble-like appearance excellent in texture and deep feeling can be formed in a simple manner.
A method for producing artificial marble having a stripe pattern by curing liquid resins in a molding cell, comprising injecting a liquid resin in which a coloring agent is dispersed non-uniformly into a molding cell, laminating one or more liquid resins having different colors to form one or more layers on the liquid resin in which a coloring agent is dispersed non-uniformly, and moving a comb-like tool through the laminated liquid resins while allowing teeth of the tool to contact the bottom surface of the molding cell to produce a striped pattern formed from an upper layer liquid resin which flows to the bottom of the molding cell.
