The present invention provides an anti-reflection material and a polarizing film which can exhibit excellent anti-reflection properties and can obtain a visible image without glittering and without reducing an image contrast while exhibiting an excellent wear resistance and chemical resistance, as well as, exhibiting an excellent stain resistance. A surface-roughened layer (,) is provided on one surface or double surfaces of a transparent substrate (,) directly or via another layer, and the surface-roughened layer (,) comprises an ultraviolet-curing resin comprising at least an epoxy compound and a photo-cationic polymerization initiator.

Anti-reflection material and method for producing the same

The invention provides an antiglare material which exhibits excellent antiglare property by preventing shining of external light in a display and is suitable for display of vivid and high-definition images free of any glare, and a polarizing film using the same. The antiglare material includes a transparent substrate provided with a roughened surface layer on one or both sides thereof. The roughened surface layer is formed from an ultraviolet curing resin containing at least an epoxy compound and a photo-cationic polymerization initiator, and beads of a crosslinked acrylic resin. The polarizing film is constructed by laminating a first protective material, which is provided with a roughened surface layer formed from an ultraviolet curing resin containing at least an epoxy compound and a photo-cationic polymerization initiator, and beads of a crosslinked acrylic resin on one side thereof, on one side of a polarizing substrate, and laminating a second protective material on the other side of the polarizing substrate. The crosslinked acrylic resin beads include at least 60 wt. % of particles having a particle size ranging from 0.5 to 6.0 .mu.m and less than 20 wt. % of particles having a particle size greater than 6.0 .mu.m. The HAZE values of the transparent substrate and first protective material fall within a range of 3-30.
