Embodiment
[0154] The present invention is specifically illustrated by examples below, but the present invention is not limited by these examples. In addition, "part" means a mass part.
[0155]
[0156] The copper layer of the glass epoxy board|substrate in which the circuit was formed with the 18 mm thick copper layer was treated and roughened with CZ8100 (surface treatment agent containing an organic acid, Meck Co., Ltd. product). Next, the resin composition layer of the photosensitive film with a support obtained in Examples and Comparative Examples was laminated using a vacuum laminator (manufactured by Nichigo Motorton Co., Ltd., VP160) so that the surface of the copper circuit was in contact with the resin composition layer. , to prepare a laminate in which the above-mentioned glass epoxy substrate, the above-mentioned resin composition layer, and the above-mentioned support are sequentially laminated. The crimping conditions were performed at a crimping temperature of 80° C., ...

[0187]
[0188] Add 2050 g (equivalent: 10.0) of cresol novolac epoxy resin [DIC Co., Ltd., EPICLONN-660, epoxy equivalent weight 205], 360 g (equivalent: 5.0) to 700 g of diethylene glycol monoethyl ether acetate. ), and 1.5 g of hydroquinone, heated and stirred at 90° C., and dissolved uniformly. Next, 5.9 g of triphenylphosphine was added, and the temperature was raised to 120° C. to react for 12 hours. The obtained reaction solution was diluted with a solvent to obtain an acrylate compound (Product A),
[0189] ? Epoxy equivalent: 427
[0190] ?Acid value: 0.49mgKOH / g
[0191] ?Weight average molecular weight: 2000
[0192] • A diethylene glycol monoethyl ether acetate solution having a solid content of 65% by mass.

[0193]
[0194] Add bixylenol type epoxy resin (Mitsubishi Chemical Co., Ltd. YX4000, epoxy equivalent 185) 190g, bisphenol acetophenone (phenolic hydroxyl equivalent 145) 14g, biscresol fluorene (JFE Chemical ( Co., Ltd., 170 g of phenolic hydroxyl equivalent weight 190), and 150 g of cyclohexanone were stirred and dissolved. Next, 0.5 g of a tetramethylammonium ammonium chloride solution was added dropwise, and reacted at 180° C. for 5 hours under a nitrogen atmosphere. Next, the temperature was lowered to 60° C., and 100 parts of ethyl isocyanate methacrylate (manufactured by Showa Denko Co., Ltd., trade name Karenz MOI, methacryloyl equivalent weight: 155) and dibutyltin dimethacrylate were added dropwise through the dropping channel (dropping lot). The mixed solution of 0.04 parts of lauric acid esters, after completion|finish of dripping, kept the reaction system at 70 degreeC for 4 hours, and the isocyanate group disappeared by this, and the methacrylate compound was ...
