Composition including particles and two liquid phases and related process

Abstract

A curable composition includes 25 to 70 volume percent particles, 25 to 74.8 volume percent of a primary liquid phase, and 0.15 to 20 volume percent of a secondary liquid phase, based on the total volume of the curable composition. The primary liquid phase includes a first monomer containing at least one of n-butyl acrylate, an alkyl acrylate monomer, or an alkyl methacrylate monomer, wherein alkyl is linear or branched and has at least five carbon atoms. The secondary liquid phase and the primary liquid phase form separate phases after mixing within a temperature range of from −20° C. to 30° C., and the particles are insoluble in the primary liquid phase and in the secondary liquid phase within a temperature range of from −20° C. to 30° C. A pressure-sensitive adhesive precursor capillary suspension, a pressure-sensitive adhesive made from a capillary suspension, and a process for making a pressure-sensitive adhesive are also described.
