A primary object of the present invention is to provide a polarizing plate excellent in durability. A polarizing plate (100) according to an embodiment of the present invention includes: a polarizer (10); and a protective film (21 and 22) arranged on at least one side of the polarizer (10). The polarizing plate (100) has a dimensional change ratio of 0.2% or more in a transmission axis direction thereof when the polarizing plate (100) cut into a size measuring 100 mm by 100 mm is bonded to a glass plate with a pressure-sensitive adhesive and the following operation is repeated 100 times: the polarizing plate (100) bonded to the glass plate is left to stand under an atmosphere at 40 C. for 30 minutes and then left to stand under an atmosphere at 85 C. for 30 minutes.

A process for the production of a polymeric article directed to (a)forming apply having successive layers, namely, (i) a first layer made up of strands of an oriented polymer material; (ii)a second layer of a polymeric material; (iii)a third layer made up of strands of an oriented polymeric material, wherein the second layer has a lower peak melting temperature that of the first and third layers; (b)subjecting the ply to conditions of time, temperature, and pressure sufficient to melt a proportion of the firsts layer to melt the second layer entirely, and to melt a proportion of the third layer, and to compact the ply; and (c)cooling the compacted ply. The resultant articles have good mechanical properties yet may be made at a lower compaction temperature than articles not employing the second layer, leading to a more controllable manufacturing process.
