The present invention provides an anti-transfer floor tile including a high hardness layer and a method for manufacturing the same. 1. An anti-transfer floor tile , comprising: a printed layer , a high hardness layer , and a lower layer ,wherein the high hardness layer comprises at least one polymer resin selected from the group consisting of: polyethylene resin, polypropylene resin, ABS resin, polyvinyl chloride resin, acrylic resin, polyester resin, polystyrene resin, polytetrafluoroethylene, ethylene-vinyl acetate copolymer, ethylene propylene copolymer, thermoplastic polyurethane (TPU), andthe high hardness layer comprises a plasticizer in an amount ranging from 5 to 20 phr and a filler in an amount ranging from 50 to 300 phr.2. The anti-transfer floor tile of claim 1 , wherein the high hardness layer has a plasticizer and filler content ratio (plasticizer:filler) in a range from 0.02 to 0.4:1 by weight.3. The anti-transfer floor tile of claim 1 , wherein a specific gravity of the high hardness layer is in a range from 1.5 to 2.5.4. The anti-transfer floor tile of claim 1 , wherein the polymer resin included in the high hardness layer is the same as polymer resins included in the printed layer and the lower layer.5. The anti-transfer floor tile of claim 1 , wherein each layer is bonded without an adhesive.6. The anti-transfer floor tile of claim 1 , further comprising an intermediate layer on the lower layer and an upper layer on the printed layer.7. The anti-transfer floor tile of claim 1 , further comprising an anti-noise layer below the lower layer.8. The anti-transfer floor tile of claim 6 , further comprising a dimension stabilization layer between the lower layer and the intermediate layer claim 6 , or between the intermediate layer and the printed layer.9. The anti-transfer floor tile of claim 6 , further comprising a surface protection layer on the upper layer.10. The anti-transfer floor tile of claim 1 , wherein each layer is bonded by heat fusion.11. A ...
