PROBLEM TO BE SOLVED: To obtain a laminate excellent in designability, which improves a luminance efficiency of a fluorescence emission display in a fluorescence emission laminate expressing different color phases under visible light and under ultraviolet irradiation. SOLUTION: The laminate emits light by irradiation with an ultraviolet source. A fluorescence emission layer (A) showing a fluorescence emission and an ultraviolet reflection layer (B) which is transparent or semi-transparent in an ultraviolet reflection coefficient of 10% or above at the total range of the wavelength region 300-400 nm are laminated from the side irradiated with the ultraviolet. Further, a transparent base material (C) is laminated so as to contact with at least one of the (A) and the (B). COPYRIGHT: (C)2010,JPO&INPIT |
