[0167] (6) Organic peroxides:

[0168] In the case of using an organic peroxide-based initiator compound, generation of radicals as an active source can be performed with very high sensitivity.

[0169] "Organic peroxides" (6) as other examples of the initiator compound (compound (B)) used in the present invention include almost all organic compounds containing one or more oxygen-oxygen bonds in the molecule. Examples include: methyl ethyl ketone peroxide, cyclohexanone peroxide, 3,3,5-trimethyl-cyclohexanone peroxide, methylcyclohexanone peroxide, acetylacetone peroxide, 1 , 1-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane, 1,1-bis(tert-butylperoxy)cyclohexane, 2,2-bis(tert-butyl Butane peroxide, tert-butyl hydroperoxide, cumene hydroperoxide, di-isopropylbenzene hydroperoxide, p-methane hydroperoxide, 2,5-dimethylhexane-2,5- Dihydrogen peroxide, 1,1,3,3-tetramethylbutyl hydroperoxide, di-tert-butyl hydroperoxide, tert-butyl...

[0601] (preparation of carrier)

[0602] Etching was performed by immersing an aluminum plate having a thickness of 0.3 mm in 10% by weight sodium hydroxide at 60° C. for 25 seconds, washed with running water, neutralized and rinsed with 20% by weight of nitric acid, and then washed with water. In 1% by weight nitric acid aqueous solution, the anode current is 300 coulomb / dm 2 , using a sinusoidal alternating current waveform, electrolytic roughening was performed on the obtained aluminum plate. Next, after immersing the obtained aluminum plate in 40 degreeC 1 weight% sodium hydroxide aqueous solution for 5 seconds, it immersed in 30 weight% sulfuric acid aqueous solution, and performed desmutting treatment at 60 degreeC for 40 seconds. Then, in 20% by weight sulfuric acid aqueous solution, the current density is 2A / dm 2 Next, anodize the aluminum plate for 2 minutes so that the thickness of the anodized film is 2.7g / m 2. The surface roughness was measured and found to be ...

Abstract

A photosensitive composition containing: a sensitizing dye represented by the formula (1) as defined herein; an initiator compound capable of generating a radical, an acid, or a base; and a compound whose physical or chemical characteristic irreversibly changes by at least one of a radical, an acid, and a base.

Description

technical field [0001] The present invention relates to a photosensitive composition which cures at high sensitivity by exposure and to a novel compound for its use. In detail, the present invention relates to a photosensitive composition used as a photosensitive layer of a lithographic printing plate precursor forming an image by digital signal-based scanning exposure, and to a novel dye compound having excellent photothermal conversion performance. Background technique [0002] Here, a PS plate having a structure in which a lipophilic photosensitive resin layer is provided on a hydrophilic support is widely used as a planographic printing plate. As for its production method, in general, a desired printing plate is obtained by dissolving and removing non-image areas after exposure from a mask of a lithographic film (surface exposure). [0003] In recent years, digital technology of electronic processing, storage and output of image information using computers have become w...
