    • The object of the present invention is to provide a producing method for a lengthwise optical laminate exhibiting high contrast ratio and adaptable to a large-sized display.The present invention provides a producing method for a lengthwise optical laminate, which comprises a step 1 of coating and drying a coating solution comprising a birefringent material and a solvent on a surface of a lengthwise base material to form a birefringent film such that a birefringence index (Δnxz[590]) in the thickness direction at a wavelength of 590 nm is 0.02 or more, and produce a lengthwise sheet (A) comprising the base material and the birefringent film; a step 2 of drawing a lengthwise film of a hydrophilic polymer containing a dichroic material so that a draw ratio is from 3 times to 5 times based on the original length and a neck-in ratio is 55% or less to produce a lengthwise polarizer (B); and a step 3 of laminating the lengthwise sheet (A) obtained in the step 1 on one plane of the lengthwise polarizer (B) obtained in the step 2 to produce the lengthwise optical laminate.
    • 本发明的目的是提供一种显示高对比度并适应于大尺寸显示器的纵向光学层叠材料的制造方法。 本发明提供一种纵向光学层叠体的制造方法,该方法包括在纵向基材的表面上涂布并干燥包含双折射材料和溶剂的涂布溶液以形成双折射膜的步骤1,以使双折射率 (&Dgr; nxz [590])在波长590nm处的厚度方向为0.02以上,并且制造包括基材和双折射膜的纵向片材(A) 绘制含有二色性材料的亲水性聚合物的纵向膜的步骤2,使得基于原始长度的拉伸比为3倍至5倍,并且收缩率为55%以下以产生纵向偏振片( B); 以及将在步骤1中获得的纵向片材(A)层叠在步骤2中获得的纵向偏振片(B)的一个平面上以制造纵向光学层压体的步骤3。

The present invention provides a producing method for a lengthwise optical laminate, which comprises a step 1 of coating and drying a coating solution comprising a birefringent material and a solvent on a surface of a lengthwise base material to form a birefringent film such that a birefringence index (Anxz[590]) in the thickness direction at a wavelength of 590 nm is 0.02 or more, and produce a lengthwise sheet (A) comprising the base material and the birefringent film; a step 2 of drawing a lengthwise film of a hydrophilic polymer containing a dichroic material so that a draw ratio is from 3 times to 5 times based on the original length and a neck-in ratio is 55% or less to produce a lengthwise polarizer (B); and a step 3 of laminating the lengthwise sheet (A) obtained in the step 1 on one plane of the lengthwise polarizer (B) obtained in the step 2 to produce the lengthwise optical laminate.
