An adhesive composition for a polarizing plate includes a specific (meth)acrylic polymer (A), an ionic liquid (B) and an isocyanate-based crosslinking agent (C) each in a specific amount. When an adhesive layer obtained from the adhesive composition for a polarizing plate is provided on a surface of a polarizing plate, the adhesive layer is appropriately plasticized and has improved compatibility with an adherend. Thus, the adhesive layer can eliminate the problems of separation or lifting due to the deflection caused by the weight of the polarizing plate, which is significant when a large polarizing plate is laminated to a liquid crystal cell. Furthermore, the adhesive layer can follow fine unevenness on a surface of glass that is a liquid crystal cell substrate, and thus can reliably prevent the separation or lifting of the polarizing plate from the liquid crystal cell even at a high temperature or under a hot and humid environment. The adhesive layer provides excellent adhesion to the liquid crystal cell.

A firm but pliable medical device for use as a bone graft substitute or bone graft extender retains its shape without the requirement of a containment device, such as a syringe. Because the device is solid, it is easy to locate or position in-vivo and, in the moist environment of the body, it will hold its shape well, for an extended time. Because the lyophilized pliable medical device is porous, it adsorbs blood and other beneficial cells containing body fluids, such as bone marrow, contributing to its superior bone repair efficacy in comparison to an analogous putty that has not been lyophilized. In addition these lyophilized pliable medical devices are easier to terminally steam sterilize than the analogous putty because there is no moisture present to boil and “blow-out” of the containment device (syringe). The glycerin that is present in the formulation lends pliability but has a low vapor pressure.
