Abstract

Self-adhesive polymer having a relative permittivity of more than 4.5 useful as a matrix of a self-adhesive electroluminescence mass.

Claims (6)

1. A self-adhesive electroluminescent composition comprising 1% to 90% by weight of a particulate phosphor and a self-adhesive having a relative permittivity of more than 4.5.

2. The electroluminescent composition of claim 1 , wherein the particulate phosphor is present in the electroluminescent composition in a mass fraction of between 40% and 75% by weight.

3. The electroluminescent composition of claim 1 wherein the particulate phosphor is a phosphor comprising encapsulated zinc sulfide.

4. A method for bonding components of optical display devices and/or lighting devices which comprises bonding said components with the self-adhesive electroluminescent composition of claim 1 .

5. A self-adhesive sheetlike element comprising an electroluminescent composition of claim 1 .

6. An electroluminescent device comprising an at least substantially transparent first electrode, a second electrode, and an electroluminescent composition of claim 1 .
