<P>PROBLEM TO BE SOLVED: To provide a laminated sheet for optical purposes, which is excellent in flaw resistance with high transmittance, and can prevent adhesion of foreign matter by dust or the like. <P>SOLUTION: An easily adhesive layer 12 is formed on one surface of a support 11 formed of biaxially-stretched polyester. A protective layer 13 is formed on the other surface of the support 11. The protective layer 13 includes: a binder that is a water-soluble or water-dispersive polymer; organic fine particles; a betaine-based antistatic agent having an imidazolium skeleton; and a lubricant. According to this, a laminated sheet excellent in flaw resistance with high transparency, and which can prevent adhesion of foreign matter by dust or the like can be obtained. Luminance unevenness decreases by using the laminated sheet for a diffusion sheet. Further, front luminance rate increases by using it for a prism sheet. <P>COPYRIGHT: (C)2009,JPO&INPIT |
