Disclosed herein is a composition for anti-reflection coating which comprises a perfluoroalkyl sulfonic acid, an organic amine, a polyvinyl pyrrolidone, a water-soluble alkylsiloxane polymer, and water. The composition is able to be an anti-reflection coating film which has a low refractive index, reduces the degree of forming insoluble layer, and does not generate fine particles and minute crystalline matters in its surface layer.
