Water-dispersed pressure-sensitive adhesive composition, pressure-sensitive adhesive and pressure-sensitive adhesive sheet
Abstract:
Provided is a water-dispersed pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive that exhibits good adhesiveness to a non-polar adherend and maintains its properties at a low temperature. The water-dispersed pressure-sensitive adhesive composition according to the present invention comprises a (meth)acrylic polymer obtained by polymerizing a monomer composition containing as a primary component an alkyl (meth)acrylate having an alkyl group with 1 to 18 carbon atoms, a latex containing a rubber component that is immiscible with the (meth)acrylic polymer and has a loss tangent peak temperature of −5° C. or below when determined by a dynamic viscoelastic measurement in which shear strain is applied at a frequency of 1 Hz, and a tackifier that is miscible with the rubber component, but immiscible with the (meth)acrylic polymer.
