Problems solved by technology

If the heat aging stability is low, dark polymerization will proceed in the lithographic printing plate precursor due to heat aging, and as a result, on-press developability will decrease
In addition, in lithographic printing plate precursors containing acid-developing dyes such as leuco dyes, there is a problem of ring-shaped color development due to heat and time.

Embodiment

[0656] Hereinafter, the present invention will be described in detail through examples, but the present invention is not limited to these. In addition, among the polymer compounds, except for the specifically specified polymer compounds, the molecular weight is the weight average molecular weight (Mw) as a polystyrene conversion value obtained by gel permeation chromatography (GPC), and the ratio of the repeating unit is the mole percentage . In addition, unless otherwise specified, "parts" and "%" mean "parts by mass" and "% by mass". In addition, Me represents a methyl group.

Synthetic example 1

[0657] [Synthesis Example 1: Synthesis of Compound 1]

[0658] (Synthesis of intermediate SM-5)

[0659] The synthesis scheme of intermediate SM-5 is shown below.

[0660] [Chemical formula 43]

[0661]

[0662] Add 217.2g (1.12mol) of 5-methyl-2,3,3-trimethylindole (the above SM-1) and 3-methoxypropyl tosylate (the above SM-1) to a 3L three-necked flask -2) 305.7 g (1.25 mol) and stirred at 120°C for 3.5 hours to obtain intermediate SM-3. After cooling this reaction liquid to 60 degreeC, 976.3 g of isopropanol was added, and it stirred at 40 degreeC. Furthermore, the aforementioned SM-4 was added to 265.0 g (0.50 mol) and 127.8 g (1.25 mol) of acetic anhydride. After 316.6 g (3.13 mol) of triethylamine was dropped, the mixture was stirred at 80°C for 2 hours. This reaction liquid was cooled to 5 degreeC, 500g of distilled water was added, and it stirred for 1 hour. The precipitated solid was collected by filtration, washed with 1000 g of distilled water, and dried with an air dr...

[0676] (Synthesis of Compound 2)

[0677] The synthesis scheme of compound 2 is shown below.

[0678] [Chemical formula 46]

[0679]

[0680] To a 100L three-necked flask, 2.23 g (0.004 mol) of the above intermediate SM-6 and 20 ml of methanol were added, and 0.32 g (0.008 mol) of a 50% by mass aqueous sodium hydroxide solution was further added and stirred for 30 minutes to prepare SM-6. Dissolve. Next, 1.34 g (0.002 mol) of synthesizable SM-7 was added and dissolved by a known method. 10 ml of water was added thereto and stirred for 1 hour. Then, the precipitated solid was recovered by filtration, washed with 20 g of distilled water, and dried at room temperature to obtain 1.8 g (0.0019 mol) of compound 2.

[0681] The structure of the obtained compound 2 was identified by NMR. Below, the results of the evaluation are shown.

Abstract

Provided are: a curable composition including a salt compound provided with a) an organic anion of which the values of the Hansen solubility parameters [delta]d, [delta]p, and [delta]H are respectively 16 or higher, in the range of 16-32 inclusive, and not more than 60% of [delta]p, and b) a counter cation; a lithographic printing plate precursor provided with an image recording layer including the curable composition; a method for preparing a lithographic printing plate which uses the lithographic printing plate precursor; and a compound which is used in the image recording layer of the lithographic printing plate precursor.

Description

Technical field [0001] The invention relates to a curable composition, a lithographic printing plate precursor, a method for making a lithographic printing plate, and a compound. Background technique [0002] A curable composition, wherein the photocurable composition is a composition having a property of being partially cured by irradiation of light, and a coating liquid formed by appropriately dissolving or dispersing the composition in a solvent is applied to a suitable support And it is dried to form a photocurable film, and an image forming material can be produced. Examples of image forming materials include lithographic printing plate precursors, printed wiring boards, color filters, photomasks, and the like that are cured by image exposure. [0003] The following is an example of a planographic printing plate precursor. [0004] Generally, a lithographic printing plate is composed of a lipophilic image portion that receives ink during a printing process and a hydrophilic no...
