Abstract:
The present invention relates to a photocurable composition and an encapsulated device including a barrier layer made of the composition. More specifically, the present invention includes a photocurable monomer and a phosphorous monomer which is represented by chemical formula 1. The photocurable monomer according to one embodiment of the present invention includes 1 to 30 monomers having a substituted or non-substituted vinyl group, an acrylate group, or a methacrylate group.
Abstract:
The present invention relates to a photo curable composition comprising (A) a photo curable monomer and (B) a monomer comprising a hydroxyl group of the following chemical formula 1, a barrier layer comprising the same, and an encapsulated device comprising the same. The present invention can form a high organic barrier layer having a significantly low out gas generation amount and a high attachment to an inorganic barrier layer, and can form an organic barrier layer having a high photo curable ratio, so that not generating a shift after cured.
Abstract:
PURPOSE: A photocurable adhesive composition is provided to have excellent outdoor visibility, to minimize substrate corrosion by having 4 or more of pH, to minimize shrinkage at curing, and to have excellent elongation, light transmittancy, and adhesion. CONSTITUTION: A photocurable adhesive composition comprises 35-75 wt% of a urethane (meth)acrylate resin 5-30 wt% of a hydroxy group-containing polybutadiene, 15-40 wt% of a photocurable monomer, and 1-5 wt% of a photoinitiator. The pH of the photocurable composition is 4 or more, curing shrinkage ratio of 3% or less, elongation due to ASTM D638 is 200-800%, and modulus is 10-50 kPa. The mixing ratio of the urethane (meth)acrylate resin and the hydroxy group-containing polybutadiene is 70:30-95:5.
