Definitions

  • the present invention relates to a lithographic printing plate precursor assured of good image visibility after exposure and a lithographic printing method using the same. More specifically, the present invention relates to a lithographic printing plate precursor from which a printing plate can be directly produced by scanning an infrared laser based on digital signals of a computer or the like and which are assured of good image visibility after exposure and usable for printing without passing through a development processing step, and also relates to a lithographic printing method of performing printing by using the lithographic printing plate precursor.
  • a photosensitive lithographic printing plate precursor is exposed to an image pattern at a low to medium illumination intensity, and the property changes in the image pattern induced from a photochemical reaction in the image-recording layer is utilized in the implementation of image recording.
  • an area to be exposed is radiated with a large quantity of light energy in an extremely short period of time to convert the light energy efficiently into beat energy, this heat energy induces thermal changes such as chemical changes, phase changes, or morphological or structural changes in the image recording layer, and these changes are utilized in the implementation of image recording.
  • a lithographic printing plate precursor comprising a support and an image recording layer capable of drawing an image by exposure with an infrared laser, wherein the image recording layer comprises (A) an infrared absorbent and (B) an iodonium salt represented by the following formula (1): Ar 1 —I ⁇ circle around (+) ⁇ —Ar 2 Z ⁇ circle around ( ⁇ ) ⁇ (1) wherein Ar 1 and Ar 2 each represents a benzene ring which may have a substituent, provided that two benzene rings are differing in the substituent from each other and the total of Hammett's ⁇ values of substituents on at least one benzene ring is a negative value, and Z represents a counter anion.
  • the lithographic printing plate precursor may allow for printing by loading it on a printing press without passing through a development processing step after recording an image or by recording an image after loading it on a printing press.
  • a cyanine dye preferred are a cyanine dye, a squarylium dye, a pyrylium salt, a nickel thiolate complex and an indolenine cyanine dye, more preferred are a cyanine dye and an indolenine cyanine dye, still more preferred is a cyanine dye represented by the following formula (I):
  • n and n each represents an integer of 1 to 3, provided that m+n is from 2 to 4. In view of sensitivity, it is preferred that m is 1 and n is 3, or m is 2 and n is 2.
  • the film thickness of the hydrophilic film is preferably 0.1 ⁇ m or more, more preferably 0.3 ⁇ m or more, and particularly preferably 0.6 ⁇ m or more, in the aspects of the anti-damaging property and the resistance to printing. Furthermore, in the aspect of the production costs, it is preferable, upon consideration of the requirement of enormous energy to construct a thick film, that the film thickness be 5 ⁇ m or less, more preferably no more than 3 ⁇ m, and particularly preferably 2 ⁇ m r less.
  • hydrophilization treatment is carried out on the surface of the aluminum plate.
  • Such hydrophilization treatment may be exemplified by the methods using alkali metal silicates as described in the specifications of U.S. Pat. Nos. 2,714,066, 3,181,461, 3,280,734 and 3,902,734.
  • the support is subjected to the immersion treatment or electrolysis treatment using an aqueous solution of sodium silicate or the like.
  • a test pattern was image-exposed by an image setter (Trendsetter 3244VX, manufactured by Creo) at a beam intensity of 10.2 W and a drum rotation speed of 150 rpm.
  • Coating Solution (1) for Water-Soluble Overcoat Layer having the following composition was coated by a wire bar to give a dry coated amount of 1.5 g/m 2 and then dried at 100° C. for 90 seconds to produce a lithographic printing plate precursor.
  • the produced lithographic printing plate precursor was evaluated in the same manner as in Example 1. The results are shown in Table 2.
