    Abstract: A pressure-sensitive-adhesive layer attached polarizing film comprises a polarizing film in which a transparent protective film is laid on/over at least one surface of a polarizer to interpose an adhesive layer between the surface and the transparent protective film, and a pressure-sensitive-adhesive layer laminated on a transparent protective film side of the polarizing film. The adhesive-layer-laid surface of the polarizer is subjected to an activating treatment. The adhesive layer is a cured product layer of an adhesive composition. The adhesive composition comprises an active-energy-ray-curable component, and a shrinkage inhibitor having a structural formula having an M-O bond wherein M is silicon, titanium, aluminum or zirconium, and O represents an oxygen atom.

    Abstract: A plastic optical fiber includes a plastic optical fiber body and a coloring member covering a peripheral surface of the plastic optical fiber body. The coloring member is made from a cured product of a curable composition containing an active-energy-ray-curable multifunctional acrylate and a coloring agent. The reaction percentage yield of the vinyl group of the active-energy-ray-curable multifunctional acrylate in the coloring member is 85% or more.
