The inkjet ink of the present invention may further contain a phenol resin or a ring as needed. An oxygen resin, an epoxy curing agent, a surfactant, a coloring agent, a polymerization inhibitor, a solvent, etc. ❹ The inkjet ink of the present invention preferably contains at least a weight average molecular weight of 300 to 12,000, and a ? molecule An acid-modified epoxy (meth)acrylic acid having a weight greater than two or more polymerizable double bonds and having more than one carboxyl group, (A)' photopolymerization initiator (8), and having a large = equal to i molecule a compound (c) having a radically polymerizable double bond; wherein, in the molecule of 1 or more, a compound having one or less free filamentity, preferably a monofunctional monomer having a cyclic structure (C1) Is a monofunctional monomer having a cyclic structure C1) is a monomer (C2) having one or more carboxyl groups in i. It is an acid-modified epoxy (meth)acrylic acid of the present invention: a molecular weight of ~12, _, and In the i molecule) = 3 4 in the 2 kakissen pour bond and 1 or more filaments = ΐ 丙烯酸 丙烯酸 i i i 裟 的 的 的 的 的 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 双 双 双Imino group. The polymerizable double bond may have a thermal polymerization property of < For the light I combined weight acrylic vinegar (4) in terms of polystyrene conversion of 300~12, _ range, preferably 700~ 11 201024380 32133pif 11,500 range, better is 900~11, 〇 (8) The range, and thus the better, is in the range of 900 to 8,000, and particularly preferably in the range of 9 〇〇 to 6 〇〇 (). When it is in this range, film properties such as etching resistance and plating resistance are excellent, and ejection characteristics are also good. Further, the obtained cured film was also excellent in solubility in the test, and the insoluble component did not become a residue. Here, the weight average molecular weight in the present specification is a THF-based column manufactured by p〇lymer Laboratories as a column, by Gpc (gd pe pemeation Chr0mat0graphy, gel permeation chromatography) method (column temperature: 35 C, The value obtained by the flow rate··1 ml/min). Further, the weight average molecular weight of the commercially available product in the present specification is a catalogue value. The acid-modified epoxy (meth) acrylate (A) has two or more polymerizable double bonds in the ruthenium molecule, and the number of preferred polymerizable double bonds and the acid oxygen (mercapto) acrylate vinegar (A) The molecular weight is related, so it is difficult to specify only I and the number. For example, it is preferably 2 to 4, and more preferably ~35, and then preferably 2 to 3, especially preferably 2 The material is 2 to 15 pieces. When the number of the silk bond (four) bond is equal to two, the film can be formed into a solid coffee structure and can be formed into an etch-resistant film. On the other hand, when the === solid of the polymerizable double bond, the hardening shrinkage can be lowered, so that the substrate and the cured film are in good contact with each other. In addition, in the case of "polymeric double bond equivalent === number of polymerizable double bonds plus == good 疋200 (g/equivalent)~_(equivalent)~(10) amount, especially good is two: 12 201024380

JziMpir (g/ though). The polymerizable double bond equivalent means the molecular weight of the acid-modified epoxy (methyl) 7 dibasic acid ester (A) divided by the acid-modified epoxy (meth)acrylic acid (A) 1 molecule. A value obtained by the number of polymerizable double bonds. The number of the acid-modified epoxy (meth) acrylate (A) having 1 or more carboxyl groups in one molecule is preferably the same as that of the acid-modified epoxy (fluorenyl) acrylic acid (A). The molecular weight side is therefore difficult to specify only for its number. For example, it is preferably 1 to 4G, more preferably 2 to 35, and preferably = 2 to 3, especially The good is 2 ~ 2 〇 a particularly good is 2 ~ 15. When it has at least one carboxyl group, the hardening enthalpy can be provided to the alkaline peeling liquid. On the other hand, if it is less than or equal to the same, the mineralization resistance of the cured film can be maintained. Therefore, if it is within these ranges, the solubility in alkali is good and does not occur. The undissolved component becomes a residue after the peeling step. In addition, film properties such as plating resistance and etching resistance are also good, and the balance between alkali peeling property and etching resistance and plating resistance is good. Further, when the number of carboxyl groups contained in the acid-modified epoxy (meth) acrylate (A) is described as "carboxy equivalent", it is 35 〇 (g/eq) to 2000 (g/equivalent). (acid value is equivalent to 3 〇 mg KOH / g) 'better 400 (g / equivalent) ~ 9 〇〇 (g / equivalent) (acid value equivalent to 60 mgKOH / g ~ 130 mgKOH / g), better It is 45 〇 (g / ^ 篁) ~ 8 〇〇 (g / equivalent) (acid value is equivalent to 70 mg K 〇 H / g ~ 120 mg KOH / g), and further preferably 500 (year-old equivalent) ~ 7 〇〇 ( g/equivalent) (acid value equivalent to 80 mgKOH/g to 110 mgKOH/g), particularly preferably 53 〇 (g/eq) to 660 (g/eq) (acid value equivalent to 85 mgK〇H/g~ 1〇5 13 201024380 32133pif mgKOH/g). The term "equivalent" refers to the value obtained by dividing the molecular weight of the acid-modified epoxy (meth) acrylate (A) by the number of carboxyl groups contained in the acid-modified epoxy (meth) acrylate (4) i molecule. . Specific examples of the acid-modified epoxy (meth)acrylic acid g (A) include an epoxy (methyl and polybasic acid) obtained by reacting an epoxy group with a reduced (meth)_ meaning and an epoxy compound.

Photolithography. In the method of manufacturing an electronic circuit board using the photolithography method, for example, when a wiring board is printed, a photoresist layer is formed on a copper foil of a copper foil laminate, and the surface thereof is exposed through a mask or the like, and then removed. A resist pattern is formed without uncured portions. Next, the copper foil of the portion not covered by the photoresist pattern is removed by etching, and the photoresist pattern is removed, whereby a printed wiring board can be obtained.
