Title:
ADHESIVE COMPOSITION FOR ORGANIC ELECTROLUMINESCENT DISPLAY DEVICES, ADHESIVE LAYER FOR ORGANIC ELECTROLUMINESCENT DISPLAY DEVICES, POLARIZING FILM EQUIPPED WITH ADHESIVE LAYER FOR ORGANIC ELECTROLUMINESCENT DISPLAY DEVICES, AND ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/034151
Kind Code:
A1
Abstract:
The present invention provides an adhesive composition for bendable organic electroluminescent (EL) display devices which is capable of inhibiting deterioration of an organic EL element by being used in a bendable organic EL display device. Furthermore, the adhesive composition for bendable organic EL display devices is capable of forming an adhesive layer for bendable organic EL display devices which does not break, peel, crease or the like during bending (flexing), exhibits excellent flexing resistance, inhibits bleed out of an ultraviolet absorbing agent or the like therein, and exhibits excellent stain resistance. This adhesive composition for bendable organic EL display devices includes: a base polymer including a monofunctional monomer as a monomer component; an ultraviolet absorbing agent; and a dye compound of which the maximum absorption wavelength in the absorption spectrum is present in the wavelength range of 380-430 nm. The adhesive composition for bendable organic EL display devices is characterized in that the total amount of the ultraviolet absorbing agent and the dye compound included therein is 0.1-15 parts by weight per 100 parts by weight of the monofunctional monomer.
