Problems solved by technology

For example, OLEDs generally include a functional organic material layer that exists between a pair of electrodes containing metal or metal oxide, and the organic material layer is peeled off from the interface of the electrodes due to the influence of moisture in the external environment, and the resistance value decreases due to the oxidation of the electrodes by the moisture. increase, or the organic material deteriorates, thus causing problems such as loss of emission function or reduced luminescence

Embodiment 1

[0097] (1) Preparation of pressure-sensitive adhesive composition

[0098] 5% by weight of nanoclay modified with bis(hydrogenated tallow)dimethyl quaternary ammonium ion (trade name: Cloisite93A, manufacturer: Southern Clay Products) was added to xylene and mixed using an impeller. In addition, the obtained mixture was dispersed with an ultrasonic generator for about 1 hour, thereby preparing a dispersion liquid.

[0099] A polyisobutylene resin (weight average molecular weight: 1,000,000) was added to xylene so that the solid content was 10% by weight. Subsequently, 40 parts by weight of a hydrogenated terpene resin (softening point: 100° C.) was added to the above xylene and mixed with respect to 60 parts by weight of the polyisobutylene resin, thereby preparing a solution containing a binder resin.

[0100] The prepared dispersion liquid was added to the solution containing the binder resin so that the solid content of the modified nanoclay was 10 parts by weight relative...

Abstract

Provided are a pressure-sensitive adhesive composition, a pressure-sensitive adhesive film, and an organic electronic device. The exemplary pressure-sensitive adhesive composition may provide an encapsulating layer of the pressure-sensitive adhesive film and the organic electronic device, which exhibits excellent moisture blocking property, transparency, durability and reliability at a high temperature and high humidity, step difference compensating property and adhesive strength.

Description

technical field [0001] The present application relates to pressure sensitive adhesive compositions, pressure sensitive adhesive films and organic electronic devices. Background technique [0002] Pressure sensitive adhesive films can be used to protect components or devices that are sensitive to external factors such as moisture or oxygen. Elements or devices capable of being protected by the pressure-sensitive adhesive film may include, for example, organic electronic devices, solar cells, or secondary batteries such as lithium secondary batteries. Specifically, among the elements or devices, organic electronic devices are susceptible to external factors such as moisture and oxygen. [0003] The organic electronic device is a device including a functional organic material. A photovoltaic device, a rectifier, an emitter, or an organic light emitting diode (OLED) may be used as the organic electronic device or an organic electronic element included in the organic electronic...
