SURFACE UNEVENNESS FORMING METHOD, OPTICAL FILM AND DIFFUSE REFLECTION PLATE EACH OBTAINED BY THE SAME AND METHOD FOR MANUFACTURING DIFFUSE REFLECTION PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method for easily and stably obtaining a surface uneven shape having a through hole at low cost and to provide an optical film and a diffuse reflection plate using the same.

SOLUTION: The surface unevenness forming method is achieved by sequentially carrying out a group (A) of surface unevenness forming steps including a step for forming an energy-sensitive negative resin composition layer containing one or more polymerizable monomers or oligomers, a step for irradiating the layer once or more with active energy rays through a patterned mask and a step for postbaking the layer without carrying out etching and a group (B) of through hole forming steps including a step for irradiating the energy-sensitive negative resin composition layer once or more with active energy rays through a mask in which a light shielding pattern for a through hole has been formed and a step for removing the layer in the through hole portion by prescribed etching.
