Abstract:
Provided is a durable abrasive article which can conform even to a surface of a complicated shape and has an excellent abrasive power and which does not give any deep flaw to become a problem at a subsequent step and is not broken even when used in sanding the surface of the complicated shape. The abrasive article comprises a flexible resin film, an abrasive grain layer formed on the surface of the resin film, and an extremely flexible resin layer formed on the abrasive grain layer, wherein the flexible resin film has a thickness of 10 to 200 μm, a tensile strength of 30 to 130 MPa and an elongation of 3 to 250%, wherein the abrasive grains of the abrasive grain layer are of P280 to P12, and wherein the extremely flexible resin layer has a 100% M of 1 to 20 MPa, a tensile strength of 20 to 90 MPa and an elongation of 250 to 1000%.
