Title:
PH RESPONSIBLE MICROCAPSULE
Document Type and Number:
Japanese Patent JP2003200035
Kind Code:
A
Abstract:
To provide a novel pH responsible microcapsule which uses a graft copolymer making an aliphatic ester chain with an amino group on the terminal a graft chain as wall material for microcapsule.
This pH responsible microcapsule is prepared from a polymer compound which consists essentially of a macromonomer having a polymerization reactive double bond on the one side terminal of an aliphatic polyester, on the other hand, having the amino group on the other terminal and represented by formula (1) or which consists essentially of a graft copolymer having aliphatic polyesters as side chains, having amino groups on the terminals of the side chains and containing the repeated units represented by formulae (3) and (4).
