Abstract
The present invention aims to provide a luminescent curved glass which, despite being curved with a small radius of curvature, can provide a clear display on its entire surface when irradiated with light, and curved digital signage including the luminescent curved glass. Provided is a luminescent curved glass including a laminate including a transparent plate having a radius of curvature of 3,000 mm or lower and a luminescent sheet, the luminescent sheet containing a thermoplastic resin and a luminescent material that emits visible light having a wavelength of 380 to 750 nm under excitation light.
Claims9
A luminescent curved glass comprising
- a laminate including a transparent plate having a thickness of 1.5 mm to 15 mm and a radius of curvature of 3,000 mm or lower, and a luminescent sheet,
- wherein the luminescent sheet contains a thermoplastic resin, a luminescent material that emits visible light having a wavelength of 380 to 750 nm under excitation light, and a plasticizer,
- the thermoplastic resin is a polyvinyl acetal resin and/or an ethylene-vinyl acetate copolymer resin, and
- an amount of the luminescent material in the luminescent sheet is 0.001 parts by weight or more and 10 parts by weight or less relative to 100 parts by weight of the thermoplastic resin.
