Zusammenfassung:PURPOSE:To manufacture the card in a maintenance-free manner by forming a latent image through a pattern exposure to a photosensitive material using a photosensitive microcapsule and overlapping this image on a developer layer on the base of the card, pressurizing and transferring the image. CONSTITUTION:A microcapsule layer 2 is provided on the support 3 of a capsule sheet 1. Each microcapsule contains a dye precursor of different color such as yellow, magenta and cyan. In addition, each microcapsule contains three different types of a photocuring composition with a spectral sensitivity in each wavelength area such as blue, green and red, for instance, against each dye precursor. Next, an image of a color copy is exposed to a capsule sheet 1 while an exposure color is selected by a color filter, and thereby a latent image is formed. After this, the microcapsule layer 2 of the capsule sheet 1 is overlapped on a developer layer 5 provided on the base 6 of an image-receptive sheet (card), then is pressurized to form a color image. Thus the card can be manufactured promptly in a maintenance-free manner.
