<P>PROBLEM TO BE SOLVED: To provide a transparent pressure-sensitive adhesive functional film which includes a functional layer for exerting scratch resistance and/or antireflection function and a pressure-sensitive adhesive layer for fixing by laminating to the adherend and in which interference fringes hardly occur and corrosion resistance is excellent. <P>SOLUTION: The pressure-sensitive adhesive functional film includes at least one functional layer selected from the group consisting of a hard coat layer and an antireflection layer on one surface of a transparent substrate, and a pressure-sensitive adhesive layer on the other surface of the transparent substrate, wherein a total amount of an acrylic acid ion and a methacrylic acid ion, extracted from the pressure-sensitive adhesive functional film with pure water under the condition of 100°C and 45 min, is ≤20 ng/cm<SP POS="POST">2</SP>per unit area of the pressure-sensitive adhesive layer, as measured by an ion chromatograph method, and an approximate integral value calculated by using a transmittance curve at a wavelength of 400 to 780 nm is ≤50, as measured by a spectral transmittance meter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
