Title:
OPTICAL LAMINATE
Document Type and Number:
Japanese Patent JP2015093419
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a colloidal crystal cured film which can be formed even on a resin substrate having low solvent resistance.SOLUTION: There is provided an optical laminate in which a primer layer (P) and a colloidal crystal cured film layer (C) are sequentially laminated on a resin substrate, the colloidal crystal cured film layer (C) is obtained by curing core-shell particles (A) having a core part and a shell part and a monomer (B), the core-shell particles (A) are regularly and periodically arranged in the cured film layer, the core part has an average particle diameter of 50 to 900 nm, the refractive index of the core part satisfies a predetermined expression, one end of the shell part is a linear polymer covalently bonded to the core part, the primer layer (P) is a cured product of an epoxy(meth)acrylate or an urethane(meth)acrylate having two or more (meth)acryloyl groups in one molecule and an acrylic equivalent of 120 to 500.
