Title:
ACRYLIC FILM, METHOD FOR PRODUCING SAME, LAMINATE FILM, LAMINATED INJECTION MOLDED ARTICLE, AND METHOD FOR PRODUCING RUBBER-CONTAINING POLYMER
Document Type and Number:
WIPO Patent Application WO/2014/038679
Kind Code:
A1
Abstract:
Provided is an acrylic film having few fish eyes. Also provided is a method for producing latex of an acrylic rubber-containing polymer in which the amount of coarse particles is extremely low, and which exhibits excellent filtering properties and has a low filter clogging frequency during a filtration step for removing foreign substances. An acrylic film containing an acrylic rubber-containing polymer (G) and having a thickness of 30 to 300 μm, wherein the number of fish eyes that are 0.001 mm2 or greater in size is 130/m2 or 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 by using a surface inspection device per 1 m2 of the acrylic film. A laminate film formed by laminating the aforementioned acrylic film and a layer of at least one resin selected from among a thermoplastic resin, a thermosetting resin, and a photocurable resin. A laminated injection molded article formed by laminating the aforementioned acrylic film on an injection molded article.
