(57) [Summary] [Structure] A core composed of a (co) polymer having a specific glass transition point, and a copolymer containing a vinyl cyanide monomer and a carbonyl group-containing monomer as essential components. An aqueous dispersion of multi-layer particles composed of a shell part composed of a coalescence, wherein the glass transition point of the shell part copolymer is the core part. A carbonyl group-containing copolymer aqueous dispersion having a glass transition temperature higher than that of the (co) polymer and a weight ratio of the core portion to the shell portion within a specific range. [Effect] As a binder for textile resin processing, it is particularly flexible for pigment printing with excellent fastness, dry cleaning resistance, blocking resistance, etc., excellent in substrate adhesion, heat resistance, etc. It is useful as a binder for a coating agent having good properties or a binder for a backing agent for carpet. |
