Description
技术领域
本发明涉及适用于平版印刷版涂料的新材料,以及涉及含这些材料的印刷版、涂层和涂布液。更具体地说,这些新材料和涂布液适用于制备通过近红外激光辐射直接数字成像的平版胶印版的涂层。
背景技术
在印刷机上可显影的阴图平版胶印版(negative-working lithographic offset printing plate)是现有技术已知的。例如,US专利5,569,573教导了包含激光成像层、含有在亲水聚合物粘合剂中的微胶囊化亲油材料的平版印刷版。EP0 770 495A1教导了包含近红外吸收材料、聚合物粘合剂和在热作用下能聚结的热塑性塑料颗粒的平版印刷版。US专利6,983,694教导了涂有近红外敏感涂料组合物的在印刷机上可显影的阴图胶印版,所述涂料组合物包含诸如聚苯乙烯或丙烯腈-苯乙烯共聚物颗粒之类的热塑性聚合物颗粒、非反应性亲水聚合物粘合剂和近红外吸收染料。
此外,US专利6,262,740教导了涂有近红外敏感涂料组合物的阴图胶印版,所述涂料组合物含有甲氧基甲基丙烯酰胺共聚物、酚醛树脂、碘盐和近红外吸收染料。US专利6,124,425和6,177,182教导了涂有热近红外吸收聚合物的在印刷机上可显影的阴图胶印版,所述聚合物在暴露于近红外辐射时通过阳离子聚合发生交联反应。近红外发色部分通过醚和铵键官能化到聚合物骨架上。US专利6,960,422教导了阴图胶印版,它含有近红外敏感底漆组合物,所述底漆组合物包含分子近红外染料、自由基生成物、可自由基聚合的尿烷化合物、反应性聚合物粘合剂和其它添加剂。
此外,US专利6,969,575和7,001,704教导了带有成像层、包含近红外吸收微胶囊和酸生成化合物的在印刷机上可显影的阴图胶印版。US专利6,582,882和未决US专利申请10/066,874;10/119,454和2005/0123853教导了涂有热可成像组合物的在印刷机上可显影的阴图胶印版,所述热可成像组合物含有聚合物粘合剂、引发剂体系和可聚合组分。所述聚合物粘合剂是带有非反应性聚环氧乙烷和聚丙烯嵌段的共 聚物,或含有与丙烯腈、苯乙烯和其它单体共聚的非反应性聚环氧乙烷侧链的接枝共聚物。可聚合组分是含多个丙烯酸官能团的粘性液态低聚物。引发剂体系含近红外吸收染料和自由基生成化合物,如三嗪,和碘鎓盐。
所有上述涂料组合物和印版都具有一些缺点,如具有造成处理和贮存困难的粘性表面、发生相分离和/或表面结晶、难以制备、需要高激光功率来实现成像、基体粘结性差和由此导致的无法提供足够的印刷机上运行时间、在印刷机上不可显影、具有差的耐刮擦性、需要罩面涂层和/或特殊的基体表面处理以及制备成本高。
因此仍需要适用于平版印刷版的能克服现有技术中部分或全部缺点的新材料和新涂料。
