【摘要】 光热敏微胶囊信息记录技术充分结合热敏微胶囊信息记录技术和辐射固化技术,集光信息的记录、存贮和再现为一体,既可应用于数字影像领域又能达到银盐信息记录技术的记录水平,有望在将来成为一种新型光信息记录技术和数字信息复现技术。光热敏微胶囊材料的热显影特性是其重要性质,其显影后的影像密度情况可以直接反映其成像质量。本文介绍了光热敏微胶囊材料的制备过程,对光热敏微胶囊材料的选材、光敏波段以及粒度的影响因素进行了分析,在制备得到成像单元(最小可在0.5μm左右)达到传统银盐胶片中卤化银微晶大小的光热敏微胶囊的基础上,进一步以光热敏微胶囊信息记录材料的热显影特性为研究对象进行了分析研究。设计制作了热显影装置,利用该显影装置,实现了100-150℃范围内、1-10s内的精确控温,为对所制备的光热敏微胶囊记录材料进行热显影特性研究提供了基础；通过对囊壁材料的差热分析确定了囊壁材料的玻璃点转化温度；利用热显影装置对涂布制备的光热敏材料进行了热显影研究,通过对显色剂的微胶囊化,降低了记录材料的灰雾,改善了材料记录信息的保存稳定性；研究了不同显色剂分散方式对影像密度的影响,研究了显影温度和显影时间对影像密度的影响；确定的优选的热显影条件为：单位体积涂布液中染料与显色剂的质量比为1／2.2,热显影温度为130℃,热显影时间为4s,这些显影条件为对该型材料进行进一步研究乃至实用化生产提供了技术参考。更多还原

【Abstract】 Photo-heat sensitive microcapsule technology for information recording combined heat-sensitive microcapsule technology with photo-harden technology. It can record, store and display optical information, and can both be used in the field of digital image technology and reach the information recording level of silver salts materials. Therefore, this technology may well become a promising optical information recording technology and digital information display technology in the future. The heat developing properties, which can directly reflected the imaging quality of this material, are the most important properties of photo-heat sensitive microcapsule material.In this thesis, the preparation process of photo-heat sensitive microcapsule was introduced. The selection principle of preparation materials, the photo-sensitive wavelength band and the granularity of microcapsules were analyzed. On the basis of the successful preparation of microcapsule, which diameter was as small as that of silver salts microcrystal, the heat-sensitive properties of prepared microcapsules were studied.In this thesis, the heat developing device was produced. It can control temperature 100-150℃and time 0-10s precisely. Through the DTA curve of the wall material, the glass transition temperature was obtained. By the heat developing device, the heat developing properties of photo-heat sensitive materials were studied. Through the microcapsulation of developer, fog in the material was reduced, while the preservation stability of recorded information was enhanced. Relations between imaging density and the three influencing factors (the processing agents dispersing styles, developing temperature and developing time) were obtained. The preferential developing temperature was 130℃, the preferential developing time was 4s, and the optimum ratio of dye to developer was 1 to 2.2. The optimum conditions could provides a basis for further research and industrial production either.更多还原
