Abstract
Composite particles are provided, including: a copolymer, and a tackifier, in which the copolymer has a first structural unit derived from a monomer (a1) and a second structural unit derived from a monomer (a2), the monomer (a1) is a nonionic compound having only one ethylenically unsaturated bond, and the monomer (a2) is a compound having a carboxy group and only one ethylenically unsaturated bond.
