Document Type and Number:
Japanese Patent JP7239490
Kind Code:
B2
Abstract:
[Problem] To provide: an anti-fogging film capable of sustainably exhibiting excellent anti-fogging properties; and an acrylic block copolymer for forming same. [Solution] The present invention pertains to: an acrylic block copolymer which comprises repeating hydrophilic blocks and hydrophobic blocks, and which is characterized in that (1) the solubility parameter of a polymer that constitutes a hydrophobic block is less than 10 [cal/cm2]1/2 and the solubility parameter of a polymer that constitutes a hydrophilic block is 10 [cal/cm2]1/2 or more, and (2) the hydrophobic block is a polymer having a glass transition temperature of 50°C or lower; and an anti-fogging film containing the acrylic block copolymer.
