Curved polarizing sheet protected with polycarbonate and process for producing the same.

摘要

A process for producing a curved polarizing sheet having a polycarbonate protective layer, which comprises laminating a polycarbonate film or sheet on both sides of a polarizing film comprising a high polymer film containing an orientated dichroic dye to prepare a polarizing laminate and forming the polarizing laminate so as to have a curved surface while heating at a temperature ranging from 120 DEG C to a temperature higher than the glass transition temperature of the polycarbonate by 30 DEG C and applying a force of 1.2 Kg/cm<2> or less to the polarizing laminate before the heating temperature reaches the glass transition temperature of the polycarbonate; and a product obtained thereby are disclosed. The curved polarizing sheet is free from optical strain and excellent in impact strength.
