Verfahren zur Erzeugung eines dreidimensionalen Bildes und Trennmittel für das Bild

摘要

A three-dimensional image formation process and an image separating agent used therefor are provided. The process comprises the steps of passing a flowable image forming material through a perforated stencil sheet having a perforated image from one surface to the other to form a three-dimensional image consisting of a flowable image forming material (ex. silicone resin) corresponding to the perforated image of the stencil sheet on the other surface; pushing out an image separating agent (ex. CaCO3 paste) from the stencil sheet side to the three-dimensional image side to form a separation layer between the three-dimensional image and the stencil sheet; hardening the three-dimensional image in this condition; and separating the three-dimensional image from the stencil sheet. The above image separating agent contains a fine particulate thixotropic agent (ex. CaCO3) as a main component, and has one minute spread value SP of the following formula: $$ wherein\; X\; is\; the\; weight\; percent\; of\; the\; fine\; particulate\; thixotropic\; agent.\mathop{\mathrm{image}}$$
