Abstract

An acrylic film having few fish eyes and a method for producing latex of an acrylic rubber-containing polymer having low amounts of coarse particles, excellent filtering properties, and low filter clogging frequency during a filtration step for removing foreign substances. An acrylic film containing an acrylic rubber-containing polymer and a thickness of 30 to 300 μm, wherein the number of fish eyes that are 0.001 mmor greater in size is 130/mor fewer when a section having a light transmission rate of 75% or less for light having a wavelength of 400 to 1100 nm was detected as a fish eye A laminate film formed by laminating the acrylic film and a layer of at least one resin selected from thermoplastic resin, thermosetting resin, and photo curable resin. A laminated injection molded article formed by laminating the acrylic film on an injection molded article.
