Surface conservation manner of the polarizing plate conservation with the polarizing plate surface conservation film and said surface conservation film and the polarizing plate which uses the said surface conservation film

摘要

To provide a polarizing plate surface-protecting film which has a peelable adhesive layer to the surface of a polarizing plate ON one side of a plastic film and does not float in a tunnel like and even when subjected to a thermal treatment process. SOLUTION: This polarizing plate surface-protecting film satisfies the following expressions (1) to (3) in the relation of the film with a polarizing plate to which the film is adhered. [F (MD) - P (MD)]+ [F (TD-P (TD)] =0.3(1), F (MD) - P (MD) =0.4(2), F (TD) - P (TD) =0.4(3) [F (MD) and F (TD) are the dimensional change rates of the polarizing plate surface-protecting film in its flow direction (MD) and width direction (TD), respectively; P (MD) and P (TD) are the dimensional change rates of the polarizing plate in its flow direction (MD) and width direction (TD), respectively.
