preparation example Construction
[0131]
[0132] The composition of the present invention can be prepared by mixing component (A) to component (C), and optionally component (D) to component (E), and other components at a predetermined ratio, preferably by dissolving in an appropriate solvent. The prepared composition is preferably filtered, for example, with a filter having a pore size of about 0.2 μm.
[0133] As the solvent, one which dissolves or disperses the respective components uniformly without reacting with the respective components can be used. Examples of the solvent include alcohols such as methanol, ethanol, isopropanol, butanol, and octanol; ethyl acetate, butyl acetate, ethyl lactate, γ-butyrolactone, propylene glycol monomethyl ether acetate, Propylene glycol monoethyl ether acetate, 3-methoxymethyl propionate, 3-ethoxy ethyl propionate and other esters; ethylene glycol monobutyl ether, propylene glycol monomethyl ether, diethylene glycol (ethylene diglycol) mono Ethers such as methyl ethe...
Embodiment
[0181] Hereinafter, the present invention will be further specifically described based on examples, but the present invention is not limited to these examples. "Parts" mean "parts by mass" in the description of the following Examples and the like, unless particularly mentioned.
[0182] [Weight average molecular weight (Mw), number average molecular weight (Mn) and degree of dispersion (Mw / Mn)]
[0183] The Mw and Mn of the resin were measured by gel permeation chromatography (GPC method) under the following analysis conditions using Tosoh GPC columns (two G2000HXL columns, one G3000HXL column, and one G4000HXL column). The degree of dispersion (Mw / Mn) was calculated from the measurement results of Mw and Mn.
[0184] (analysis conditions)
[0185] Dissolution solvent: tetrahydrofuran
[0186] Flow: 1.0mL / min
[0187] Sample concentration: 1.0% by mass
[0188] Sample injection volume: 100μL
[0189] Column temperature: 40°C
[0190] Detector: Differential refractom...
Synthetic example 1
[0196] 10 parts of 2,2'-azobis-(2,4-dimethylvaleronitrile) and 200 parts of methyl 3-methoxypropionate were put into the flask equipped with the cooling pipe and the stirrer. Next, 10 parts of methacrylic acid, 25 parts of 3,4-epoxycyclohexylmethyl methacrylate, and 65 parts of cyclohexyl acrylate were injected|thrown-in. After nitrogen substitution, stirring was started slowly. The temperature of the solution was raised to 75° C., and the temperature was maintained for 5 hours, whereby a solution containing the alkali-soluble resin (A-1) was obtained. The solid content concentration of the solution was 34.2% by mass, Mw of the resin (A-1) was 8,300, and Mw / Mn was 2.0.
[0197] [Synthesis Example 2 to Synthesis Example 12]
[0198] Except for using the types and compounding amounts of the components shown in Table 1 as monomers, the same procedure as in Synthesis Example 1 was carried out to obtain a compound containing alkali-soluble resin (A-2) to alkali-soluble resin (A...
