Hollow particles, method for producing hollow particles, and resin composition

Abstract

To provide hollow particles configured to improve adhesion to resin. Hollow particles which comprise a shell containing a resin and a hollow portion surrounded by the shell, wherein, as the resin, the shell contains a polymer which contains 60% by mass or more of crosslinkable monomer units; wherein the hollow particles have amino groups on a surface thereof; and wherein an amine amount per unit area of the hollow particles, which is obtained by the following formula (A) using an amine value of the hollow particles and a specific surface area of the hollow particles, is 5.00 μmol/m2 or more: Amine amount (μmol/m2)=Amine value (μmol/g)/Specific surface area (m2/g) Formula (A).
