Artificial marble composition and production method for artificial marble using same

An artificial marble composition comprising:

• a first resin mixture;
• and
• a second resin mixture added to the first resin mixture,
• wherein a viscosity of the second resin mixture is different from a viscosity of the first resin mixture,
• wherein each of the first and second resin mixtures comprises:
• a base resin;
• an inorganic filler;
• a chip, wherein an amount of the chip ranges from 10 parts by weight to 100 parts by weight based on 100 parts by weight of the base resin;
• and
• a catalyst, wherein the catalyst is an organic amine or an organic metal salt, and wherein an amount of the catalyst is 1 part by weight or less based on 100 parts by weight of the base resin,
• wherein the first resin mixture and the second resin mixture are mixed with each other, and a weight ratio between the first resin mixture and the second resin mixture ranges from 1:1 to 10:1, and
• wherein the second resin mixture further comprises a thixotropic agent, and wherein an amount of the thixotropic agent ranges from 0.5 part by weight to 3.0 parts by weight based on 100 parts by weight of the second resin mixture.
