    摘要: A method for forming selectively colored printing plates using photosensitive recording elements is disclosed wherein the photosensitive recording element contains a photopolymerizable recording layer comprising a photopolymerizable monomer, a radical photoinitiator, a color former, and a color photoinitiator. A method for producing a printing plate from the photosensitive recording element involves exposing the back surface of the recording layer to a dose of actinic radiation, imagewise exposing the front of the photopolymerizable recording layer to another dose of actinic radiation thereby forming exposed and unexposed areas on the front of the recording layer wherein the exposed areas are cured and undergo a color change by exposure to the actinic radiation, and then removing the unexposed areas of the imagewise exposed recording layer thereby forming an image in relief wherein the image portion and the non-image portion are of different color and wherein the contrast between these portions due to the color difference is visually detectable.

    摘要: Selectively colorable polymerizable compositions and a method for forming selectively colored polymeric bodies using such compositions are disclosed. In accordance with the invention, a selectively colorable polymerizable composition comprising both a leucobase color former and a leuconitrile color former is irradiated with light of a particular wavelength and specific intensity for a specified duration. Exposure to actinic radiation cures the composition and activates the color formers. The irradiation dosage can be varied to selectively color the polymeric body whereby the resultant color of any particular area depends on the exposure dose received at that location. By varying the dose, a polymeric body can be prepared having distinctly colored elements at specific locations.

In accordance with the invention, a selectively colorable polymerizable composition comprising a leucobase color former is irradiated with light of a particular wavelength and specific intensity for a specified duration.
