Thermal transfer film, and organic electroluminescent device prepared using same

摘要

The present invention relates to a thermal transfer film and to an organic electroluminescent device prepared using same, wherein the thermal transfer film includes a base film and an outermost layer which is formed on the base film and has 2% or more of a thickness change ratio expressed by formula 1.

主权项

1. A thermal transfer film comprising:
a base film; and an outermost layer formed on the base film, wherein the outermost layer has a thickness change rate of about 0.5% or more, as calculated according to Equation 1:
Thickness change rate (%)=(T2−T1)/T1×100,   (wherein Equation 1, T1 is an initial thickness of the outermost layer, T2 is a maximum thickness of the outermost layer, as measured within a temperature range from 25° C. to 170° C. while the thermal transfer film is heated at a heating rate of 5° C./min from a starting temperature of 25° C. to a final temperature of 170° C.).
