摘要： Provided is a process for producing a pressure-sensitive adhesive sheet by laminating layers of active-energy-ray-curable compositions and irradiating the laminate with an active energy ray. The processes gives a pressure-sensitive adhesive sheet with less defects at low production cost and is applicable to the production of pressure-sensitive adhesive sheets of various kinds. The process includes: Steps A1 and A2 of applying an active-energy-ray-curable composition to one surface of a first carrier and to one surface of a second carrier using a die coater to form coated layers thereon; Step B of placing the resulting first and second carriers so that the coating-layer-side surfaces of the carriers face each other, and introducing an active-energy-ray-curable composition into between the first and second carriers; and Step C of irradiating a multilayer assemblage with an active energy ray, the multilayer assemblage obtained in Step B and including the active-energy-ray-curable compositions between the first and second carriers.
