    • Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images. The recording sheets are suitable for use in high speed printing applications such as computer print out paper, battery operated printers for digital camera or personal digital assistance, labels, medical imaging, and color proofing films.
    • 公开了一种用于彩色成像的光敏记录片,其包括透明支撑片,其具有设置在支撑体的一个表面上的热滑层和在支撑体的相对表面上的热敏图像层。 将第二不透明(纸)或透明(塑料)片层压到着色层。 图像层包含含有可光聚合或可光交联的化合物,光引发剂和染料前体以及微胶囊外部的显影剂材料的可光硬化微胶囊。 记录片材对光化辐射的图像曝光导致对该辐射敏感的微胶囊的选择性光硬化。 将得到的曝光记录片材加热至高于显影剂熔点的温度,例如热敏头使得显影剂能够选择性渗透非光硬化胶囊,从而形成包括全色图像在内的图像。 记录纸适用于高速打印应用,如计算机打印纸,数码相机的电池供电打印机或个人数字助理,标签,医疗成像和彩色打样胶片。
