Paper Abstract
The microcapsules can act as novel optical functional material in which the optical recording substance such as
color-forming substance, photoinitiator and prepolymer are encapsulated. In this paper, the microcapsules with average
particle diameter of 300nm are prepared with interfacial polymerization method. The optical responding character of the
microcapsule is analyzed based on IR spectra and image density technique. Results show that the microcapsule material
encapsulated prepolymer TMPTA and photoinitiator Irgacure-ITX, TPO has thermal phase-change at 140°C, at which
the penetrability of the microcapsule has the highest efficiency. With the increase of exposure time, the reduction in
absorption intensities of the prepolymer TMPTA are observed at 1635cm-1 of C=C stretching and 898cm-1 of C-H
stretching on the C=C molecular bond. Such a result can be ascribed to the double bond cleavage process of the
prepolymer TMPTA is initiated by the optical-exposed photoinitiator, and superpolymer network is formed. The image
density contrast between the unexposed and exposed microcapsule is enhanced with exposure time increased.
