Abstract
A lenticular lens sheet having ( ) a light-transmitting lens sheet body with a lenticular lens group formed of multiple lenticular lenses placed on a surface of the body and a silver salt emulsion light-shielding layer laminated to the other surface of the light-transmitting lens sheet body. Light-transmitting areas in the light-shielding layer correspond to light-converging parts of the lenticular lenses on the body. The positions of the light-shielding areas correspond to non-light-converging parts of the lenticular lenses. The light-shielding characteristics result from the darkened silver dispersed in the silver salt emulsion. A method for making the lenticular lens sheet is disclosed also.
