Embodiment 1 to 8

[0182] Embodiment 1 to 8: the preparation of carrier:

[0183] Pure and cast molten JIS Al050 alloys containing at least 99.5% Al, 0.30% Fe, 0.10% Si, 0.02% Ti and 0.013% Cu. To purify it, the alloy melt is degassed, from which unnecessary gases such as hydrogen are removed, and filtered through a ceramic tube filter. The alloy melt is cast by direct current casting. The solidified blank with a thickness of 500mm was cut 10mm deep from the surface, and then homogenized at 550°C for 10 hours while preventing the intermetallic compounds therein from forming rough grains. Then it is hot rolled at 400°C, and then annealed in a continuous annealing furnace at 500°C for 60 seconds (this is the annealing treatment), and then cold rolled into an aluminum sheet with a thickness of 0.30mm. In this way, the surface roughness rolled out by rolling can be controlled at the average height of the center line, Ra, and the average height of the center line of the cold-rolled aluminum sheet i...

Embodiment 9 and 10

[0204] A coating liquid [R] for the photosensitive layer was prepared (its composition is shown below). Immediately after preparation, the aluminum sheet was coated with the coating liquid [R] with a wire rod (the preparation method was the same as that in Examples 1-8), and then dried in hot air at 115° C. for 45 seconds. Thus, lithographic printing plate precursors [R-1] and [R-2] were prepared. After drying, the amount of photosensitive layer formed on each precursor was 1.3 g / m 2 . The infrared absorbers and radical generators used in the coating liquid [R] are given in Table 11. Coating liquid [R] for photosensitive layer: Infrared absorber (given in Table 11) 0.10 g free radical generator (given in Table 11) 0.30 g polyfunctional monomer (whose structure is given below ) 1.00 g additional 4,4'-diphenylmethane diisocyanate, ethylene diisocyanate, tetraethylene glycol and 2,2-bis(hydroxymethyl)propionic acid copolymer in a molar ratio of 30 / 20 / 30 / 20 , (weight average m...

Embodiment 11 to 14， comparative example 5 and 6

[0213] However, the printing plate [S-1] of Comparative Example, which printed a large number of good prints, is different from the printing plate of Example 9 of the present invention only in that the photosensitive layer of the former contains an infrared absorber outside the scope of the present invention. The number of good prints printed is less than that printed by the printing plate of the present invention. Examples 11 to 14, Comparative Examples 5 and 6: Preparation of the carrier:

[0214] Aluminum supports were prepared in the same manner as in Examples 1-8, except that the silicate was used for hydrophilization treatment. Inner coating:

[0215] The coating liquid (whose composition is given below) was then applied to the aluminum support with a wire rod and dried in hot air at 90°C for 30 seconds. After drying, the thickness of the inner coating formed is 10mg / m 2 . Inner coating liquid: β-alanine 0.1g propyl phosphoric acid 0.1g methanol 40g pure water 60g Ph...

Abstract

The present invention provides a negative image recording material for use in a thermal exposure system, comprising (A) an infrared absorber comprising a cyanine dye having a substituent containing an atom having an atomic weight of at least 28, such as a halogen atom , or substituents containing non-shared electron pairs such as carbonyl, (B) radical generators and (C) radical polymerizing compounds, and imaging on it requires exposure to infrared radiation.

Description

[0001] Background technology of the invention technical field [0002] The present invention relates to an image recording material useful in lithographic printing plate precursors, color inspection, photoresists and color filters, and novel cyanine dyes useful therein. In particular, the present invention relates to a negative image recording material for a thermal mode exposure system, which can be used for a lithographic printing plate precursor on which an infrared laser is scanned based on a digital signal from a computer or the like to directly manufacture a lithographic printing plate ; and relates to new cyanine dyes with high infrared absorption. Background technique [0003] For a system that can fabricate printing plates directly from computer digital data, (1) electrophotography, (2) exposure of photopolymerizable material to blue or green emitting lasers, (3) silver on photosensitive resin Salt thin printing plates, and (4) silver diffu...
