| 摘 要： | 光热敏微胶囊材料可作为新型非银盐信息记录媒质,其囊芯光敏反应是实现光信息记录的关键。本文利用傅立叶变换红外光谱技术,通过监测囊芯TMPTA单体的C=C双键在1650-1626cm-1处特征吸收峰随曝光时间的变化,发现在紫外光照射下,TMPTA分子C=C双键在光引发剂自由基作用下发生交联聚合而引起微胶囊囊芯固化,随曝光时间增长,囊芯固化程度表现为先快速增加,再到曝光20s后基本达到稳定。显影密度检测表明,光热敏微胶囊内部固化程度直接决定了后续热显影的影像密度,进而在不同曝光时间下形成了影像密度反差。

| Abstract: | The photo-heat sensitive microcapsule material can be acted as novel non-silver information recording medium,and the photo-sensitive property in microcapsule core is the key factor to affect the information recording efficiency.The C=C bonds characteristic absorption around 1650~1626 cm-1 of TMPTA monomer,which comprises of the microcapsule core compound,has been detected with FTIR spectra technique.Results imply that the C=C bonds of TMPTA has been photo-crosslinked initiated by the photoinitiator radicals... |
