Method for producing polarizing film protected on one side and equipped with adhesive layer

Abstract

A method for producing a polarizing film protected on one side and equipped with an adhesive layer, by positioning a transparent resin layer and an adhesive layer, in this order, from the polarizer side thereof onto a polarizing film protected on one side as a result of having a protective film on only one surface of the polarizer, which exhibits specific optical properties and has a thickness of10[mu]m or less, the method involving: forming a transparent resin layer by transporting the polarizing film protected on side, and while doing so, performing a step (1) for coating the polarizer-sideof the polarizing film protected on one side with a coating solution that contains a resin component or a curable component capable of forming a resin layer, and also performing a step (2) for solidifying or curing the coating solution after the coating step (1) has been performed; and thereafter, also performing a step (3) for forming an adhesive layer on the transparent resin layer without rolling the obtained polarizing film protected on one side and equipped with the transparent resin layer into a rolled shape. Thus, even when using a thin film protected on one side, it is possible to stably form a transparent resin layer and then an adhesive layer.

Description

technical field [0001] The invention relates to a method for manufacturing a single-sided protective polarizing film with an adhesive layer. The one-sided protective polarizing film with an adhesive layer obtained by the above-mentioned production method can be used alone to form image display devices such as liquid crystal display devices (LCD) and organic EL display devices, or as a single-sided protective film laminated with the above-mentioned adhesive layer. In the form of an optical film of a polarizing film, an image display device such as a liquid crystal display device (LCD) or an organic EL display device is formed. Background technique [0002] Liquid crystal display devices are rapidly expanding in market demand for clocks, mobile phones, PDAs, notebook computers, monitors for personal computers, DVD players, and TVs. A liquid crystal display device visualizes a polarization state by switching of liquid crystals, and a polarizer is currently used based on the di...

Problems solved by technology

[0006] On the other hand, the durability of the one-side protective polarizing film against the above-mentioned thermal shock is insufficient, so polarizing films provided with a protective layer (transparent resin layer) on the polarizer side have been proposed (Patent Documents 2 and 3)
