Title:
光学用活性エネルギー線重合性接着剤および光学用積層体
Document Type and Number:
Japanese Patent JP7081411
Kind Code:
B2
Abstract:
To provide an adhesive capable of well dispersing inorganic oxide particles, capable of controlling a refractive index of an adhesive layer after cured to a high level, having good transparency and excellent adhesive force under wide temperature conditions from low temperature to high temperature.SOLUTION: An active energy ray-polymerizable adhesive for an optical use is provided, which comprises: inorganic oxide particles (X) having a specific particle diameter; an epoxy (meth)acrylate oligomer (A-1) or a polyester (meth)acrylate oligomer (A-2) having a mass average molecular weight of 700 or more; and a (meth)acrylate monomer (B) having at least either a hydroxyl group or a heterocyclic skeleton and having a mass average molecular weight of 500 or less. When the epoxy (meth)acrylate oligomer (A-1) is used, the adhesive contains the acrylate monomer (B) more than the epoxy (meth)acrylate oligomer (A-1) and substantially no solvent.SELECTED DRAWING: None
