[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial marble and a method for producing the same, and more particularly to an artificial marble having a beautiful raised pattern similar to natural marble and a method for producing the same.

[0002]

2. Description of the Related Art As a conventional artificial marble and its manufacturing method, for example, a molding resin and a handle are mixed nonuniformly in a container in order to impart a pattern similar to natural marble, and this is used for molding. It was known that the composition was poured into a mold and then cured, and then cured.

[0003]

However, in such an artificial marble and the method for producing the same, the pattern of the artificial marble thus produced is attached to the surface or is present inside the molding resin layer, The depth and three-dimensional effect of the handle could be expressed only from the surface of the molding resin layer to the inside of the molding resin layer. And, as a result, such artificial marble does not exhibit a high-grade feeling sufficiently.

The present invention has been made in view of the above-mentioned facts, and its purpose is to be able to sufficiently express the depth and three-dimensional effect of a handle and to produce a high-class feeling. (EN) Provided is an artificial marble and a method for producing the same.
