Abstract: The present invention provides a thermal recording material having a thermosensitive layer comprising single phase diffuser polymer particles. Each of the diffuser polymer particles has a refractive index at the center thereof (RIcenter) different from a refractive index at the surface thereof (RIsurface), and a continuous refractive index gradient, sometimes referred to as GRIN technology. The diffuser polymer particles may have a RIcenter of from 1.46 to 1.61 and a particle size of 0.85 to 15 microns. Additionally, the thermal recording material of the present invention may also include heat deformable particles and a binder.The present invention also provides a method for providing an image by subjecting selected portions of a recording material such as that described above to a physical agent selected from the group consisting of heat, pressure, and combinations thereof, sufficient to reduce the opacity of said selected portions.

Abstract translation: 本发明提供一种具有包含单相扩散聚合物颗粒的热敏层的热敏记录材料。 每个扩散聚合物颗粒在其中心处的折射率（RIcenter）与其表面处的折射率（RIsurface）不同，并且连续折射率梯度有时称为GRIN技术。 扩散聚合物颗粒可以具有1.46至1.61的RI中心和0.85至15微米的粒度。 此外，本发明的热敏记录材料还可以包括热变形颗粒和粘合剂。 本发明还提供了一种用于通过将选自上述记录材料的选定部分从选自热，压力及其组合的物质中选出的一部分来提供图像的方法，其足以减少所选择的不透明度 部分。
