Problems solved by technology

[0005] As an adhesive composition that can be used as a low-dielectric material, a polyimide formed by reacting aromatic tetracarboxylic dianhydride and dimer diamine, a cross-linking agent such as epoxy resin, and a polyimide compound of an organic solvent are used. Imine-based adhesives are known (see Patent Document 1), but low dielectric properties may not be sufficient
[0006] On the other hand, polyimide-based adhesives excellent in low dielectric properties include cross-linking agents such as polyimides formed by reacting aromatic tetracarboxylic dianhydride and diaminopolysiloxane, and epoxy resins. , and organic solvent polyimide adhesives are known (refer to Patent Document 2), but within the range recognized by the applicant, the low dielectric properties are not sufficient

manufacture example 1

[0130] Add commercially available aromatic tetracarboxylic dianhydride (trade name " BTDA-UP ", manufactured by Ebonick Japan Co., Ltd.; 3, 3 ', 4, The content of 4'-benzophenone tetracarboxylic dianhydride is 99.9% or more) 210.0 g, cyclohexanone 1008.0 g, and methylcyclohexane 201.6 g, and the solution was heated to 60°C. Next, 341.7 g of hydrogenated dimerized diamine (trade name "PRIAMINE 1075", manufactured by Croda Japan Co., Ltd.) was added dropwise, and imidization reaction was carried out at 140° C. for 10 hours, thereby obtaining a softening point of A solution of a polyimide resin (A1-1) at about 80° C. and a weight average molecular weight of about 35,000 (30.0% of nonvolatile content). In addition, the molar ratio of acid component / amine component was 1.03.

manufacture example 2

[0132] In the same reaction vessel as in Production Example 1, commercially available aromatic tetracarboxylic dianhydride (trade name "BisDA2000", manufactured by SABIC Japan Contract Co., Ltd.; 4,4'-[propane-2,2-diylbis( The content of 1,4-phenyleneoxy)] diphthalic dianhydride is 99.5% or more), 60.0 g of cyclohexanone 165.0 g, and 27.5 g of methylcyclohexane, and the solution was heated to 60°C. Next, 59.3 g of PRIAMINE 1075 was added dropwise, and then imidization was carried out at 140° C. for 10 hours, thereby obtaining a polyimide resin (A1 -2) solution (non-volatile content 31.9%). In addition, the molar ratio of acid component / amine component was 1.05.

Embodiment 1

[0150] 100.00 g of a solution of component (A1-1), 1.67 g of tetraglycidyl xylylenediamine (trade name "Tetrad-X", manufactured by Mitsubishi Gas Chemical Co., Ltd.) as component (B) and hydroxyl-containing Polyphenylene ether (trade name "SA90", manufactured by SABIC Corporation) 1.67 g, toluene 7.87 g as (C) component, and a commercially available amino group-containing silane coupling agent as (D) component (trade name "KBM603 ", manufactured by Shin-Etsu Chemical Co., Ltd.; 0.07 g of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane) was mixed to obtain a resin composition (adhesive) with a nonvolatile content of 30.0%.

Abstract

The invention relates to a resin composition, an adhesive, a film type adhesive substrate, an adhesive sheet, a resin attached copper foil, a copper-clad laminate board and a wiring board. The invention provides a novel polyimide adhesive having an adhesive layer with good adhesiveness, heat resistance and low dielectric properties. A resin composition comprises polyimide (A1) obtained by performing reaction of a monomer group (1) comprising: an aromatic tetracarboxylic acid dianhydride (a1) having a free carboxylic acid content of less than 1 wt%; and hydrogenated dimer diamine (a2), and not comprising diaminopolysiloxane (a3).

Description

technical field [0001] The present invention relates to a resin composition, an adhesive, a film-like adhesive material, an adhesive sheet, a multilayer wiring board, a resin-coated copper foil, a copper-clad laminate, and a printed wiring board. Background technique [0002] Flexible printed wiring boards (FPWB: Flexible Printed Wiring Board) and printed circuit boards (PCB: Printed Circuit Board) and multilayer wiring boards using the above boards are used in mobile communication devices such as mobile phones and smartphones or their base station devices, servers It is widely used in network-related electronic equipment such as routers and large computers. [0003] In recent years, in these products, in order to transmit and process large-capacity information at high speed, high-frequency electrical signals are used, but high-frequency signals are easily attenuated. Therefore, it is required to suppress transmission loss as much as possible for the above-mentioned multilay...
