Abstract
The photosensitive color-producing microcapsules have been prepared with melamine/formalin resin by in situ polymerization method. The leucocompound and the photoacid generator dissolved in diisopropylnaphthalene were successfully loaded in the interior of microcapsules. Preparation of microcapsules that have uniform particle size could also be attained. Irreversible development of microcapsules was examined by an irradiation of UV light. The leucocompound in the microcapsule was sensitively reacted with the acid produced from the photoacid generator without destruction of capsule walls. It has also been found that the development in the microcapsule progresses quickly compared to the bulk condition.
