Title:
METHOD FOR MANUFACTURING POLARIZER
Document Type and Number:
WIPO Patent Application WO/2013/051553
Kind Code:
A1
Abstract:
This method for manufacturing a polarizer is provided with the following steps, in this order: an adhesive application step in which an active-energy-ray-curable adhesive is applied to one surface of a transparent film or transparent films or one or both surfaces of a polarizing film; a bonding step in which a layered body comprising the transparent film(s) layered to one or both surfaces of the polarizing film with the aforementioned adhesive interposed therebetween is sandwiched between a pair of bonding rollers rotating in the conveyance direction and pressure is applied to the layered body so as to bond the transparent film(s) to the polarizing film; and a first active-energy-ray exposure step in which the adhesive is cured by exposing the layered body to active-energy rays while said layered body is being conveyed in close contact with a roller rotating in the conveyance direction. At least one of the bonding rollers is a rotationally driven rubber roller that has a rubber surface, and the rotating roller rotates faster than said rubber roller.
