  • Patent number: 7462400
    Abstract: Disclosed herein are a caster-resistant surface laminate using a synthetic resin and a flooring comprising the surface laminate. The surface laminate utilizes buffering properties of a synthetic resin layer, thus minimizing damage to the surface of the flooring. The surface laminate uses a resin selected from PVC, PE, PET, PETG, PCTG and PU in order to enhance the caster resistance, impact resistance and water resistance. As a result, the surface laminate has improved physical properties without occurrence of damage, such as hollowing and breakage, caused by external impacts, as compared to conventional surface laminates. In addition, the caster-resistant surface laminate attains interior decorative effects by coloration of the synthetic resin layer.
