LENTICULAR LENS SHEET HAVING LIGHT-SHIELDING LAYER AND METHOD FOR MANUFACTURE THEREOF |
摘要 |
A lens sheet body 2 is prepared by laminating, to a transparent film 6, a lenticular lens layer 7 having aplurality of lenticular lenses arranged, and a silver salt emulsion layer 10 is laminated to this lens sheet body 2 on its light-emerging surface side. For example, lamination of the silver salt emulsion layer 10 to the lens sheet body 2 is conducted by backing a silver salt emulsion layer 10 with a transparent film 8 to obtain a silver salt photosensitive film 5 and adhering this silver salt photosensitive film 5 to the lens sheet body 2 with the use of an adhesive agent layer 9, with the transparent film 8 of the silver salt photosensitive film 5 facing the lens sheet body 2. Next, parallel rays 40 are applied to the lens sheet body 2 from the lenticular lens layer 7 side to expose those parts of the silver salt emulsion layer 10 that correspond to the light-converging parts of the lenticular lenses 3a. Thereafter, the silver salt emulsion layer 10 exposed is developed. As a result, there is obtained a light-shielding layer 4 having light-transmitting areas 4a in the positions corresponding to the light-converging parts of the lenticular lenses 3a and light-shielding areas 4b in the positions corresponding to the non-light-converging parts of the lenticular lenses 3a. The light-shielding areas 4b in the light-shielding layer 4 have light-shielding characteristics owing to the darkened silver dispersed in the silver salt emulsion. <IMAGE> |
