Disperse blue 2BLN with polyamide microcapsules was prepared with p-benzoyl chloride and different diamine monomers through interfacial polymerization.The particle size and size distribution of the microcapsules were detected and analyzed by Scanning Electron Microscopy.The release of the dye from the microcapsules into an acetone solution was measured by UV-Vis.It was found that with the increase of the number of the methylene units in the diamine,both the particle size and size distribution increased,and the controlled release performance was improved.
