Three-dimensional image, and methods for the production thereof

Abstract

A three-dimensional image is produced using an imaging medium having a lenticular screen, the lenticles of the screen dividing the opposed surface of the imaging medium into a plurality of elongate image areas, the imaging medium having on the opposed side thereof a radiation-sensitive layer, the radiation-sensitive layer comprising a color-forming composition adapted to undergo a change of color upon increase in the temperature of the radiation-sensitive layer above a color-forming temperature for a color-forming time. The radiation-sensitive layer is imagewise exposed to actinic radiation which does not pass through the lenticular screen, thereby causing the color-forming composition to undergo its change in color in exposed areas and to form in the radiation-sensitive layer a composite image, the composite image comprising, in each of the image areas, a plurality of image strips extending lengthwise along the image area, each of the image strips containing information from a view of the object, each of the plurality of image strips in one image area containing information from a different view of the object thereby forming a copy of the composite image in the radiation-sensitive layer, so that a three-dimensional orthoscopic image of the object will appear to an observer seeing the composite image in the radiation-sensitive layer through the lenticular screen.
