Abstract
A photopolymerizable composition is disclosed, which comprises a photopolymerizable compound and a photopolymerization initiator comprising a cationic dye, an organic boron compound and a compound having an --SH group in the molecule thereof, and which can be used for making printing plates, as resist materials for making printed circuit boards, as color proof materials, etc. The photopolymerizable composition can be applied for an image-forming process utilizing microcapsules, which comprises the steps of encapsulating the photopolymerizable composition with a color image-forming material in the core of microcapsules, coating the microcapsules on a support to form a photosensitive sheet, imagewise exposing the photosensitive sheet, superposing the photosensitive sheet on an image-receiving sheet, pressing the whole surface of the assembly to rupture the microcapsules at the unexposed portions, and transferring the color image-forming material into the image-receiving sheet. The color image obtained by using the photopolymerizable composition exhibits high sensitivity.
