    • A process to mark a multilayered article with a laser (20). The multilayered article (10) includes a laser-markable layer (14) having at least one organic polymer and at least one light-sensitive pigment therein, and including at least one release agent associated with the laser-markable layer. Laser-marking of the laser-markable layer is accomplished by directing laser radiation (22) into the multilayered article through the release agent (12) to induce an interaction between the light-sensitive pigment and the organic polymer. As a result of the interaction, a visually perceptible marking (16) is formed in the article. The laser-marked article includes a laser-markable layer and a first release agent associated with a surface of the laser-markable layer. The marking(s) in the laser-markable layer is visible through the layer of release agent, and the marking is a result of the laser-induced interaction between the light-sensitive pigment and the organic polymer.
    • 用激光(20)标记多层物品的过程。 多层制品(10)包括其中具有至少一种有机聚合物和至少一种光敏颜料的可激光标记层(14),并且包括与可激光标记层相关联的至少一种脱模剂。 可激光标记层的激光标记通过将激光辐射(22)通过脱模剂(12)引导到多层制品中以诱导感光颜料和有机聚合物之间的相互作用来实现。 作为相互作用的结果,在制品中形成视觉上可察觉的标记(16)。 激光标记制品包括可激光标记层和与可激光标记层的表面相关联的第一释放剂。 可激光标记层中的标记通过剥离剂层是可见的,并且标记是光敏颜料和有机聚合物之间的激光诱导相互作用的结果。

    • An image receptor medium including an image reception layer having two major opposing surfaces. The image reception layer comprises a polymer comprising at least two monoethylenically unsaturated monomeric units, wherein one monomeric unit comprises a substituted alkene where each branch comprises from 0 to about 8 carbon atoms and wherein one other monomeric unit comprises a (meth)acrylic acid ester of a nontertiary alkyl alcohol in which the alkyl group contains from 1 to about 12 carbon atoms and can include heteroatoms in the alkyl chain and in which the alcohol can be linear, branched, or cyclic in nature and an efficacious amount of a free-radical scavenger. Alternatively, the image receptor medium includes a substrate layer comprising a polymer substrate layer having two major opposing surfaces and an image reception layer on a first major surface of the substrate layer. The image reception layer has an outer surface for receiving images, and comprises a polymer identified above. Either embodiment of the image receptor medium may further include an optional prime layer, an optional adhesive layer, and an optional inkjet layer.
    • 包括具有两个主要相对表面的图像接收层的图像接收介质。 图像接收层包括包含至少两个单烯属不饱和单体单元的聚合物,其中一个单体单元包含取代的烯烃,其中每个分支包含0至约8个碳原子,并且其中一个单体单元包含(甲基)丙烯酸酯 非烷基烷基醇,其中烷基含有1至约12个碳原子,并且可以在烷基链中包括杂原子,其中醇可以是直链,支链或环状的,并且有效量的自由基清除剂 。 或者,图像接收介质包括基底层,该基底层包括具有两个主要相对表面的聚合物基底层和在基底层的第一主表面上的图像接收层。 图像接收层具有用于接收图像的外表面,并且包括上述的聚合物。 图像接收介质的任一实施方案可以进一步包括任选的初始层,任选的粘合剂层和任选的喷墨层。
