PROBLEM TO BE SOLVED: To improve the contrast of a visual image by constituting a lenticular sheet so that a light shielding pattern may be formed on a diffusion layer and it may directly face to an observer. SOLUTION: A film is laminated on the flat surface of the transparent resin lenticular sheet 10 so as to form the diffusion layer 20. On the diffusion layer 20 formed on the flat surface of the lenticular sheet, photosensitive resin ('Cromalin' film) 30 is laminated. Next, by irradiating the sheet with ultraviolet ray from an ultraviolet ray irradiation device, non-adhesive and adhesive parts are formed on the photosensitive resin ('Cromalin' film) 30 in accordance with the condensing and non-condensing parts based on the condensing work of a lenticular lens, thereafter, the sheet is made to pass through a pair of laminating rollers, then, a black transfer layer is transferred from a transfer sheet supplied by the rolls only to the adhesive part, then, the light shielding pattern (black stripe) 40 is formed. Besides, a protecting layer 50 is formed on the outmost surface positioned on the opposite side of a lens part. |
