POLYMERIZABLE COMPOSITION, POLYMER, OPTICAL ADHESIVE SHEET, IMAGE DISPLAY DEVICE, AND METHOD FOR PRODUCING SAME

摘要

Provided is a polymerizable composition for forming a polymer layer to be interposed between an image display part of an image display device and a light-transmissive protective part, the polymerizable composition exhibiting excellent peeling resistance with respect to the display part and the protective part. This polymerizable composition comprises a (meth)acryloyl-group-containing polymer compound having a number-average molecular weight within the range of from 1000 to 15000, and a photopolymerization initiator, wherein the polymer obtained by polymerizing said polymerizable composition has a storage modulus of from 1×103 to 1×105 Pa at 25°C at a frequency of 0.1 Hz. The polymerizable composition may also comprise, for example: a radical-polymerizable-unsaturated-group-containing compound including an alcoholic hydroxyl group and/or an amido group; a (meth)acryloyl-group-containing compound that includes no alcoholic hydroxyl group nor amide group and that has a viscosity of 500 mPa·s or less at 25°C; and/or a nonionic surfactant that includes no (meth)acryloyl group.
