Title:
ADHESIVE COMPOSITION
Document Type and Number:
Japanese Patent JP2015221891
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive composition usable for long time at low viscosity by suppressing viscosity change of an adhesive composition after preparation, and an adhesive sheet shot in curing time needed for becoming available of processing such as cutting without problem after forming the adhesive composition with a sheet shape, and excellent in processability, an optical film with an adhesive where the adhesive sheet is applied to the optical film, and an optical laminate by laminating the optical film with the adhesive on a glass substrate for example a liquid crystal cell.SOLUTION: There are provided an adhesive composition containing an acryl resin (A) which is a polymer of monomers containing (meth)acrylic acid ester (A-1) represented by the formula (I), where Rrepresents a hydrogen atom or a methyl group, Rrepresents an alkyl group having 14 or less carbon atoms, a crosslinking agent (B), an organic acid salt (C) and organic acid (D) and an adhesive sheet by forming the same with a sheet shape.
