Crosslinked polymer particles, and a manufacturing method thereof

The mother particles formed from crosslinked polymer having a functional group, in contact with the first amino compound having two or more amino groups, the reaction by crosslinking polymers with some amino groups of said functional groups Furthermore the process of crosslinking (a), after step (a), the by reaction with the functional groups remaining second amino compound and a crosslinking polymer having an amino group, a bonded mother particles and the base particles two and step (b) to obtain a cross-linked polymer particles having an amino group derived from amino compounds, can be obtained by a production method comprising a crosslinked polymer particle. .FIELD 1
