PROBLEM TO BE SOLVED: To obtain an active energy beam-curable agent for imparting resistance to contamination with which properties preventing adhesion of fingerprint and sebum and a wiping property can remarkably be improved, and further, excellent hardness/wear resistance, transparency and a low curling property can be realized by irradiating an active energy beam to cure the agent, and to provide a contamination-resistant article by using the agent. SOLUTION: In the agent for imparting resistance to contamination, pencil hardness of a coating film formed from the agent is≥5B and a contact angle with water is≥80°and contact angles with oleic acid, triolein and squalene is≤10°. The agent for imparting the resistance to contamination comprises a (meth)acrylic copolymer (A) containing (meth)acrylate having a water repellent group not containing silicon and fluorine as a copolymer component or a complex of the copolymer (A) with inorganic oxide fine particles and preferably further an organic compound having a (meth)acryloyl group curable with active energy beam. The agent enables formation of the coating film having excellent resistance to stain caused by fingerprint/resistance to stain caused by serum and simultaneously having excellent hardness, scratch resistance, transparency and low curling property, or the like. The agent can preferably be used for wide applications such as touch-resistant panels, displays, housings for cellular phones, optical discs, or the like. COPYRIGHT: (C)2005,JPO&NCIPI
