Definitions

  • U.S. Pat. No. 5,942,554 discloses a method for the formation of highly colored polymeric bodies which includes subjecting a curable composition containing a color precursor and an onium salt to heat or actinic radiation to cure the composition where the color precursor is converted to its colored form.
  • the method provides for simultaneous color development and photopolymerization of curable films using a color precursor such as a lactone and an onium salt such as iodonium or sulfonium salt.
  • the curable composition includes curable compounds, such as free-radical curable and/or cation curable monomers.
  • a photoinitator may optionally be present in the curable composition.
  • solid refers to the physical state of the layer which has a definite volume and shape and resists forces that tend to alter its volume or shape.
  • a solid layer of the photopolymerizable composition may be polymerized (photohardened), or unpolymerized, or both.
  • cyclic lactone dyes which include, but are not limited to, aminotriarylmethane compounds, amino-2,3-dihydroanthraquinones, and tetrahyhalo-p,p′-bihenols.
  • Particularly preferred cyclic lactone dyes are aminotriarylmethane compounds. Examples of suitable aminotriarylmethane compounds can be found in U.S. Pat. No. 4,857,438 column 3, line 8 through column 5, line 33.
  • Particularly preferred cyclic lactone dyes include:
  • the photopolymerizable composition may also contain an inert dye to provide the unexposed “raw” plate, i.e., photopolymerizable printing element, with a characteristic color.
  • an inert dye to provide the unexposed “raw” plate, i.e., photopolymerizable printing element, with a characteristic color.
  • the reaction of the onium salt with the leuco dye will generate a color form of the leuco dye in those portions of the photopolymerizable layer which were exposed to radiation. If the inert dye and the color form of the leuco dye are too similar in color, the color of the exposed areas and the color of the unexposed areas will not be differentiated enough to provide sufficient contrast to the image.
  • the photosensitive element includes at least one photopolymerizable layer that can be of a bi- or multi-layer construction. Further, the photosensitive element may include an elastomeric capping layer on the at least one photopolymerizable layer.
  • the elastomeric capping layer should have an elastic modulus in the polymerized state not substantially less than the elastic modulus of the photopolymerizable layer in the exposed state.
  • the composition of the elastomeric layer comprises an elastomeric polymeric binder, a second onium salt and a second leuco dye. Both the second onium salt and the second leuco dye can be the same or different than the onium salt and the leuco dye in the photopolymerizable layer.
  • the assemblage is exposed imagewise with infrared laser radiation to selectively transfer or selectively alter the adhesion balance of the radiation opaque layer and form the image on or disposed above the photopolymerizable layer as disclosed by Fan et al. in U.S. Pat. No. 5,607,814; and Blanchett in U.S. Pat. Nos. 5,766,819; 5,840,463; and EP 0 891 877 A.
  • Fan et al. in U.S. Pat. No. 5,607,814
  • Blanchett in U.S. Pat. Nos. 5,766,819; 5,840,463; and EP 0 891 877 A.
  • an elastomeric capping layer may be present next to the photopolymerizable layer and this, in turn, may be overcoated with a release layer.
  • additional layer(s) will depend on the nature of the photopolymerizable layer, whether or not the actinic radiation opaque layer is present, the nature of the radiation opaque layer and other physical requirements of the photosensitive element.
  • the infrared laser exposure can be carried out using various types of infrared lasers, which emit in the range 750 to 20,000 nm. Infrared lasers including diode lasers emitting in the range 780 to 2,000 nm and Nd:YAG lasers emitting at 1064 nm are preferred.
  • a preferred apparatus and method for infrared laser exposure to imagewise remove the actinic radiation opaque layer from the photosensitive element is disclosed by Fan et al. in U.S. Pat. Nos. 5,760,880 and 5,654,125. The in situ mask images remain on the photosensitive element for subsequent steps of overall exposure to actinic radiation and treating.
  • the developers can be organic solvents, aqueous or semi-aqueous solutions, and water.
  • the choice of the developer will depend primarily on the chemical nature of the photopolymerizable material to be removed.
  • Suitable organic solvent developers include aromatic or aliphatic hydrocarbon and aliphatic or aromatic halohydrocarbon solvents, or mixtures of such solvents with suitable alcohols.
  • Other organic solvent developers have been disclosed in published German Application 38 28 551.
  • Suitable semi-aqueous developers usually contain water and a water miscible organic solvent and an alkaline material.
  • Suitable aqueous developers usually contain water and an alkaline material.
  • Other suitable aqueous developer combinations are described in U.S. Pat. No. 3,796,602.
  • Treating the element thermally includes heating the photosensitive element having at least one photopolymerizable layer (and the additional layer/s) to a temperature sufficient to cause the uncured portions of the photopolymerizable layer to soften or melt or flow, and contacting an outermost surface of the element to an absorbent surface to absorb or wick away the melt or flow portions.
  • the polymerized areas of the photopolymerizable layer have a higher melting temperature than the unpolymerized areas and therefore do not melt, soften, or flow at the thermal development temperatures.
  • Thermal development of photosensitive elements to form flexographic printing plates is described by Martens in U.S. Pat. Nos. 5,015,556; 5,175,072; 5,215,859; and by Wang et al. in WO 98/13730.
  • Detackification is an optional post-development treatment that can be applied if the surface of the photosensitive printing element is still tacky, such tackiness not generally being removed in post-exposure. Tackiness can be eliminated by methods well known in the art, such as treatment with bromine or chlorine solutions.
  • detackification is accomplished by exposure to radiation sources having a wavelength not longer than 300 nm, as disclosed in European Published Patent Application 0 017927 and Gibson U.S. Pat. No. 4,806,506. Since the detackification step occurs at a different wavelength than the main exposure and the sensitivity of the onium salt is matched to the wavelength of the main exposure, no change in color contrast will occur as a result of detackification step. However, the presence of excess leuco dye in the photopolymerizable layer when detackifying may result in color change.
  • the coversheet was removed, and an image-bearing negative was placed on a surface of the element opposite the support, and a vacuum was drawn.
  • the element was exposed to UV light (365 nm) through the negative for 12 minutes (12 joules/cm 2 ) on the exposure unit. A change in color was observed between the exposed areas and the unexposed areas of the photopolymerizable layer. The exposed areas (polymerized portions) were dark blue whereas the unexposed areas (unpolymerized portions) remained pink-red.
