Title:
ADHESIVE TAPE HAVING WAVELENGTH CONVERSION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2017/159719
Kind Code:
A1
Abstract:
An adhesive tape having a prescribed wavelength conversion function and having excellent durability is provided. An adhesive tape according to the present invention comprises a substrate and an adhesive layer having a wavelength conversion function. The moisture vapor transmission rate of the substrate is up to 1 g/(m2⋅day). In one embodiment, the adhesive layer contains a rubber polymer selected from a styrene thermoplastic elastomer, an isobutylene polymer, and a combination thereof. In one embodiment, the adhesive layer contains at least two wavelength conversion materials including a first wavelength conversion material and a second wavelength conversion material, wherein the first wavelength conversion material has a light-emission central wavelength in a wavelength band in the range of 515-550 nm, and the second wavelength conversion material has a light-emission central wavelength in a wavelength band in the range of 605-650 nm.
