In order to implement the above-described stripe pattern in the present invention, there must be a raw material slurry having two or more colors, and the two slurries are different in color only by pigments, and their components are the same. In addition, chips of the same material or different materials may be mixed in the slurry, and the size of the chips should not be too large for process problems, and 6 to 100 mesh is suitable. The effect of the chip may be a little more scattered stripes and textures for large chips (6 to 30 mesh (0.535 to 3.35 mm)) to look more natural, and for small chips (30 to 100 mesh (0.14 to 0.535 mm)). There is no effect on stripes or texture, but you can add color.

In the present invention, as the resin, acrylic and / or unsaturated polyesters are used, and both may be used in combination. However, if the amount of the two resins is more than one (difference of 10: 1 or more in mass ratio), the interface between the two resins may be split depending on the difference in curing rate. In addition, these two resins may be used alternately to show a texture. In the case of acrylic resin, the texture is excellent, and in the case of unsaturated polyester resin, the transparency is excellent, so when the two raw materials are alternately used as lines, the same color can produce a unique feeling.

In addition, a mixture of peroxides and sulfonic acids of amines or mixtures of peroxides and cobalt compounds can be used to allow polymerization and curing to be carried out at room temperature. The content of the polymerization initiator is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the base resin syrup, and is generally used together with the polymerization accelerator.

Moreover, radical carriers, such as mercaptan compounds, such as a normal dodecyl mercaptan, a tertiary dodecyl mercaptan, a benzyl mercaptan, and a trimethyl benzyl mercaptan, can be used. The content of the radical carrier is preferably 0.1 to 5 parts by weight based on 100 parts by weight of the base resin syrup.
