    • It is an object of the present invention to provide a high performance and highly productive thermal transfer image-receiving sheet which solves drawbacks of the prior art, i.e., drawbacks such as the deterioration in sensitivity in using a pulp paper such as a coated paper as a substrate, and the reduction in productivity and the increase in cost in using a laminated and bonded sheet of a void-containing biaxially stretched film and a core material, is inexpensive, and can attain high-density and high-resolution images having no density irregularity and dot missing.A method of producing a thermal transfer image-receiving sheet in which at least an insulating layer 15 and an image-receiving layer 8 are formed in this order on a substrate 11, comprising the steps of melt-coextruding the insulating layer including a thermoplastic resin (A) and a resin or filler which is not compatible with the thermoplastic resin (A) and the receiving layer including a thermoplastic resin (B) to form a film, and then stretching this melt-coextruded film to form a layered body of a film, and then laminating the layered body on a substrate with the insulating layer side of the layered body faced with the substrate, wherein said image-receiving layer or a release layer provided on said image-receiving layer side of said layered body contains modified silicone oil and the void fraction of the insulating layer is 15 to 65%.
    • 本发明的目的是提供一种解决现有技术缺陷的高性能和高生产率的热转印图像接收片,即诸如涂布纸等纸浆纸的灵敏度劣化的缺点 基板,并且使用含空隙的双轴拉伸膜和芯材的层叠和粘合片材的生产率的降低和成本的增加是便宜的,并且可以获得没有密度的高密度和高分辨率图像 不规则和点缺失。 一种制造热转印图像接收片的方法,其中至少在衬底11上依次形成绝缘层15和图像接收层8,包括以下步骤:将包含热塑性树脂的绝缘层熔融共挤出 (A)和与热塑性树脂(A)不相容的树脂或填料和包含热塑性树脂(B)的接收层以形成膜,然后拉伸该熔融共挤出膜以形成层压体 膜,然后将层叠体层叠在基板上,层叠体的绝缘层侧面向基板,其中设置在所述层叠体的所述图像接收层侧的图像接收层或剥离层包含改性聚硅氧烷 油和绝缘层的空隙率为15〜65%。
