Document Type and Number:
Japanese Patent JP6936330
Kind Code:
B2
Abstract:
A sealing agent for organic electroluminescent display elements, which contains (A) an acyclic alkanediol di(meth)acrylate having 6 or more carbon atoms, (B) a cyclic monomer and (C) a photopolymerization initiator, and wherein the cyclic monomer (B) contains a cyclic monofunctional (meth)acrylate and a cyclic bifunctional (meth)acrylate, while satisfying the following formula (I) and formula (III). (I): 8 mPa·s ≤ η ≤ 50 mPa·s (III): γ/2η < 0.9 m/s (In the formulae, η represents the viscosity as measured at 25°C with use of an E-type viscometer; and γ represents the static surface tension as measured by a pendant drop method.)
