ANTIREFLECTION FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE

摘要

PURPOSE: An anti-reflection film, a polarizing plate and an image display device are provided to maintain anti-reflection property, scratch-resistant property and anti-fouling property, by preventing a low refractive index layer from being damaged by an alkali water solution. CONSTITUTION: An anti-reflection film includes a transparent base film consisting of triacetyl cellulose and a low refractive index layer. The low refractive index layer is formed with a curable layer of an ionizing radiation curable resin. The low refractive index layer is formed on one plane of the transparent base film. The low refractive index layer contains hollow type silica particles and has a lower refractive index than a lower layer stacked below. A polymerizable compound included in the ionizing radiation curable resin is one of a multi-functional polymerizable compound not having hydroxyl radical among the molecule, a multi-functional polymerizable compound having hydroxyl radical containing rate below 0.2 where the hydroxyl radical containing rate is defined as the value obtained by dividing the number of hydroxyl radicals included in one molecule by molecular weight and then multiplying by 100, and a multi-functional polymerizable compound having hydroxyl radical containing rate below 0.2 where there are more than one kind of polymerizable compound is included in one molecule. The functional group number of multi-functional polymerizable compound is between 3 and 9, and the molecular weight is between 300 and 1000.
