【Abstract】 microcapsules containing a basic dye precursor and an photo-curing materials as the core there of was made.The wall of the microcapsule were impermeable to both the basic dye precursor and developer at room temperature,but at a temperature of a thermal head during a recording process,become permeable to at least one of the basic dye precursor and developer,thereby permitting formation of a colored image as a result of the reaction between the basic dye precursor and developer.But because of radiation curing reaction,the core of the capsules after exposure were permeable.So the recording material containing the photo-thermal-icrocapsules could sensitive to light,and be developed by heat it.And the photo-thermal curve of the recoding material were obtained.更多还原
