PURPOSE:To increase color density and to improve the shelf stability of a non- image area by enveloping a color developing component in microcapsules and using an org. compd. having specified max. absorption wavelength in a specified spectral absorption wavelength range as a photopolymn. initiator. CONSTITUTION:At least one kind of component taking part in color development or vanishment is enveloped in microcapsules and a prescribed photopolymn. initiator is used in a photosetting compsn. for forming a latent image by exposure. This initiator is a 2-substd. phenyl-4,6-bistrihalomethyl-s-triazine deriv. having 330-345nm max. absorption wavelength in the spectral absorption wavelength range of 270-400nm in acetonitrile. |
