Abstract
The hollow particles comprise a shell containing a resin and a hollow portion surrounded by the shell. A void ratio is 50% or more. The shell contains, as the resin, a polymer in which from 60 parts by mass to 100 parts by mass of a crosslinkable monomer unit is contained in 100 parts by mass of all monomer units. The hollow particles have at least one kind of reactive group selected from the group consisting of a carboxy group, a carboxylic anhydride group and a sulfo group on a surface thereof. An acid value is 0.20 mmol/g or more.
