Pressure-sensitive adhesive composition, production method therefor, pressure-sensitive adhesive layer, and pressure-sensitive adhesive sheet

Abstract

A pressure-sensitive adhesive composition, including: (meth)acrylic resin particles having an average particle diameter of from 5 nm to 160 nm and containing a constituent unit (A) derived from an alkyl (meth)acrylate monomer, a constituent unit (B) derived from (meth)acrylonitrile, a constituent unit (C) derived from a (meth)acrylic monomer having a carboxy group, and a constituent unit (D) derived from a reactive surfactant, in which a content ratio of the constituent unit (B) is from 10 mass % to 25 mass % with respect to all the constituent units excluding the constituent unit (D), a content ratio of the constituent unit (C) is from 0.2 mass % to 6.0 mass % with respect to all the constituent units excluding the constituent unit (D), and a content amount of the constituent unit (D) is from 0.1 parts by mass to 1.0 part by mass with respect to 100 parts by mass of all the constituent units excluding the constituent unit (D); and water.
