Linsenrasterscheibe und Verfahren zu deren Herstellung

摘要

A lenticular lens sheet comprising a base member in the form of a film or sheet, and a lens area including lenticular lenses convexly formed on the light-entering surface of the base member. The lens area is formed by using an ionizing- radiation-curable resin such as an ultraviolet-light- or electron-beam-curable resin. A non-colored layer which is substantially transparent and non-colored is formed in each lenticular lens on the base side thereof; and a colored layer is formed in each lenticular lens along the light-entering surface thereof. The colored layer has the function of enhancing the contrast of the incident-side single lenticular lens sheet. According to this lenticular lens sheet, it is possible to obtain enhanced contrast by preventing the reflection of extraneous light without lowering the intensity of imaging light so much, and to make the lenticular lens pitch extremely small.
