| abstract | (Project) To provide a film containing polyvinyl alcohol, which has little coloration by heating and is excellent in the dispersed state even when it contains a surfactant. (Solution) A film containing polyvinyl alcohol having a saponification degree of 50 to 99.99 mol% and a viscosity average degree of polymerization of 200 to 5,000, wherein the content of the alkali metal salt of carboxylic acid is 0.5 mass% or less in terms of the mass of the alkali metal, The peak top molecular weight (A) measured by a differential refractive index detector when the polyvinyl alcohol heated at 120° C. for 3 hours was measured by gel permeation chromatography, and an absorption spectrophotometer (measured with a measurement wavelength of 280 nm) The peak top molecular weight (B) used is the following formula (1) (A-B)/A < 0.75 (1) is satisfied, and the absorbance at the peak top molecular weight (B) is 0.25×10 −3 to 3.00×10 −3 . |
