中文摘要： 用涂料墨水替代染料墨水是解决纺织品数码印花技术对织物适应性低、后处理耗水耗能和废水排放问题的有效途径。但涂料墨水存在易堵塞喷嘴的缺点，使得上述途径的实现面临障碍。本项目提出解决上述难题的全新思路：用单体和低聚体代替常规涂料墨水体系中的高分子粘合剂，克服墨水过早成膜堵塞喷嘴的问题；应用蓝光引发聚合技术，使喷印至织物表面的单体和低聚体在原位聚合形成粘合剂大分子固化膜，由此获得所需色牢度并省略耗能耗水并排污的后道加工工序。为达此目标，拟对喷墨印花涂料墨水蓝光引发聚合固化的相关化学基础和应用化学基础理论问题进行系统和深入的研究，包括：确定蓝光引发聚合固化体系的优化构成、研究蓝光引发聚合固化体系与着色剂体系的相容性、揭示蓝光聚合固化反应机理和固化色膜性能调控原理、建立蓝光固化墨水体系与墨水喷印性能和印制效果相关性的理论模型，为研制和应用适用于纺织品的蓝光固化数码喷印涂料墨水提供理论指导。

英文摘要： Substituting pigment ink for dye ink in digital printing technology is an effective way to solve the problems in textile digital inkjet printing, such as poor adaptability to fabrics, water and energy consumption, and pollution emissions in printing aftertreatment. However, pigment ink suffered from nozzle clogging problems, which have been hindering the realization of above way. In this project,a new train of thoughts was proposed to resolve the above problems, including the following two revolusionary changes. Firstly, monomers and oligomers will be used in the new pigment ink system to replace the polymeric binders used in a conventional pigment ink system, in oreder to conque the nozzle clogging problem; Secondary, blue light curing technology will be introduced to initiate the polymerization of the monomers and oligomers printed on the fabric in situ to form a polymer film, so that to achieve an expected colour fastness and omit the water consumption, energy consumption and pollution emissions occured in conventional printing aftertreatments. To achieve this goal, it is neccssary to do further systematically study in fundamental chemistry and application chemistry related to blue light induced polymerization and curing of ink systems, mainly including the compositions of blue light curable ink system, the c
