明細書 樹脂組成物、 その硬化物及びその物品 技術分野  TECHNICAL FIELD Resin composition, cured product thereof and article thereof
本発明は樹脂組成物、 特にフレキシブルプリント配線板等の製造に使用でき るエッチングレジスト又は保護膜 (カバ一レイ) 形成用に好適な感光性樹脂組 成物及びこれを用いた感光性フィルムに関する。 背景技術  The present invention relates to a resin composition, particularly a photosensitive resin composition suitable for forming an etching resist or a protective film (cover layer) which can be used for producing a flexible printed wiring board and the like, and a photosensitive film using the same. Background art
従来、 プリント配線板の製造には、 液状またはフィルム状の感光性樹脂組成 物が用いられている。 例えば、 銅張積層板の銅箔をエッチングするレジストと して、 配線の形成されたプリント配線板には、 はんだ付け位置の限定及び配線 の保護等に用いられている。 プリント配線板には、 カメラ等の小型機器に折り 曲げて組み込めることが可能なフィルム状のものがあり、 これはフレキシブル プリントサ一キットボード (F P C ) と呼ばれている。 この F P Cにも、 はん だ付け位置の限定及び配線の保護のためにレジス卜が必要であり、 それはカバ 一レイ又はカバーコートと呼ばれている。 カバーレイは、 接着剤層を有するポ リイミ ドゃポリエステルを所定の型に打ち抜いた後、 F P C上に熱圧着等で形 成され、 また、 カバーコートは、 熱硬化や光硬化性のインクを印刷、 硬化させ て形成される。  Conventionally, in the production of printed wiring boards, liquid or film-shaped photosensitive resin compositions have been used. For example, as a resist for etching a copper foil of a copper-clad laminate, a printed wiring board on which wiring is formed is used for limiting soldering positions, protecting wiring, and the like. Some printed wiring boards are in the form of films that can be folded and incorporated into small devices such as cameras, and these are called flexible printed circuit boards (FPCs). This FPC also requires a register to limit the soldering position and protect the wiring, and it is called a cover or cover coat. The coverlay is formed by punching a polyimide / polyester with an adhesive layer into a predetermined mold and then thermocompression bonding on the FPC.The cover coat is printed with thermosetting or photocurable ink. It is formed by curing.
F P Cのはんだ付け位置の限定及び配線の保護の目的に用いられるこれらの レジストには、 可撓性が特に重要な特性となり、 そのため可撓性に優れるポリ イミ ドカバ一レイが多く用いられている。 しかし、 このカバーレイは、 型抜き のため高価な金型が必要であり、 また、 型抜きフィルムの人手による張り合わ せ、 接着剤のはみ出し等のため、 歩留まりが低く製造コストが高くなり、 F P Cの市場拡大の障害となっており、 更に、 近年の高密度化に高密度化に対応す ることが困難となっている。 そこで、 写真現像法 (イメージ露光に続く現象により画像を形成する方法) で、 寸法精度、 解像性に優れた高精度、 高信頼性のカバーレイを形成する感光 性樹脂組成物、 特に感光性フィルムの出現が望まれてきた。 この目的のために、 ソルダマスク形成用感光性樹脂組成物を用いることが試みられた。 例えば、 ァ クリル系ポリマー及び光重合性モノマーを主成分とする感光性樹脂組成物 (特 開昭 53— 560 1 8号公報、 特開昭 54— 1 0 1 8号公報等) 耐熱性の良好 な感光性樹脂組成物として、 主鎖にカルコン基を有する感光性エポキシ樹脂及 びエポキシ樹脂硬化材を主成分とする組成物 (特開昭 54 - 82073号公報、 特開昭 58— 62636号公報等) 、 エポキシ基を含有するノボラック型ェポ キシァクリレート及び光重合開始剤を主成分とする組成物 (特開昭 6 1 - 27For these resists, which are used for the purpose of limiting the soldering position of the FPC and protecting the wiring, flexibility is a particularly important characteristic, and therefore, polyimide covers having excellent flexibility are often used. However, this cover lay requires an expensive die for die cutting, and because the die cut film is stuck by hand and the adhesive runs out, the yield is low and the manufacturing cost is high. It is an obstacle to market expansion, and it is difficult to respond to the recent increase in density. Therefore, a photosensitive resin composition that forms a high-accuracy and highly reliable coverlay with excellent dimensional accuracy and resolution by photographic development (a method of forming an image by a phenomenon following image exposure), especially photosensitive The emergence of films has been desired. For this purpose, attempts have been made to use a photosensitive resin composition for forming a solder mask. For example, a photosensitive resin composition containing an acrylic polymer and a photopolymerizable monomer as main components (JP-B-53-56018, JP-A-54-10818, etc.) Good heat resistance JP-A-54-82073 and JP-A-58-62636 disclose a photosensitive resin composition which is mainly composed of a photosensitive epoxy resin having a chalcone group in a main chain and an epoxy resin curing material. Etc.), a composition mainly composed of a novolak type epoxy acrylate containing an epoxy group and a photopolymerization initiator (JP-A-61-27)

INDUSTRIAL APPLICABILITY The photosensitive resin composition and the photosensitive film of the present invention are particularly useful as etching resists for flexible printed wiring boards and resists such as solder resists, and can also be used as paints, coating agents, adhesives, and the like. . The printed wiring board of the present invention can be obtained, for example, as follows. That is, when a liquid resin composition is used, a film thickness of 5 to 160 m is applied to a printed wiring board by a screen printing method, a spray method, a roll coating method, an electrostatic coating method, a curtain coating method, or the like. By applying the resin composition of the present invention at a temperature of 60 to 110 ° C., preferably at a temperature of 60 to 100 ° C., a tack-free coating film can be formed. After that, a photo with an exposure pattern such as a negative film The mask is brought into direct contact with the coating (or placed on top of the coating in a state where it does not come into contact with the coating) and irradiated with ultraviolet light at an intensity of about 10 to 200 mJ / cm. The unexposed portion is developed using a developing solution described later, for example, by spraying, rocking immersion, brushing, scrubbing, or the like. After that, if necessary, it is further irradiated with ultraviolet rays, and then heat-treated at a temperature of 100 to 200 ° C., preferably 140 to 180 ° C., so as to have excellent flexibility and resist. A printed wiring board having a permanent protective film that satisfies various characteristics such as heat resistance, solvent resistance, acid resistance, adhesion, and electrical characteristics of the film can be obtained. Examples of the organic solvent used in the development include octogens such as trichloroethane, aromatic hydrocarbons such as toluene and xylene; esters such as ethyl acetate and butyl acetate; 1,4-dioxane; Ethers such as tetrahydrofuran; ketones such as methyl ethyl ketone and methyl isobutyl ketone; lactones such as carb tyrolactone; butyl acetate sorb acetate, carbitol acetate, diethylene glycol dimethyl ether, propylene glycol monomethyl ether acetate Alicyclic hydrocarbons such as cyclohexanone and cyclohexanol; petroleum solvents such as petroleum ether and petroleum naphtha; water and alkaline aqueous solutions such as potassium hydroxide and sodium hydroxide; , Sodium carbonate , Potassium carbonate, sodium phosphate, Gay acid sodium, ammonia, an aqueous solution of an alkali such as amines can be used. As a method for producing a photoresist image using the photosensitive film of the present invention, when the protective film is present, the protective film is removed, and then the photosensitive film is pressure-bonded to the substrate while heating. By doing so, they can be laminated. At this time, it is preferable to laminate under reduced pressure. The surface to be laminated is not particularly limited, and is preferably an FPC on which wiring is formed by etching or the like. The heating temperature of the light-sensitive layer is not particularly limited, and is preferably 90 to 130 ° C. The pressing pressure is not particularly limited, and the pressing is preferably performed under reduced pressure. The photosensitive layer thus laminated is brought into direct contact with a photomask having an exposure pattern such as a negative film or the like (or placed on the coating film in a state where the photomask is not in contact with the photomask). Irradiate at an intensity of about 0 mJ / cm. At this time, if the polymer film present on the photosensitive layer is transparent, it can be exposed as it is, but if it is opaque, it must be removed. From the viewpoint of protecting the photosensitive layer, the polymer film is preferably transparent, and it is preferable to expose the polymer film while leaving the polymer film remaining. Suitable light sources for photocuring include low-pressure mercury lamps, medium-pressure mercury lamps, high-pressure mercury lamps, ultra-high-pressure mercury lamps, xenon lamps, and metal halide lamps. In addition, a laser beam or the like can also be used as active light for exposure. Next, after the exposure, if a polymer film is present on the photosensitive layer, the polymer film is removed and then removed by a known method such as spraying, rocking immersion, and brushing using the developing solution. The exposed portion can be removed for development. Then, if necessary, further irradiating with ultraviolet rays, and then performing heat treatment at a temperature of 100 to 200 ° C., preferably 140 to 180 ° C., provides excellent flexibility, A printed wiring board having a permanent protective film that satisfies various properties such as heat resistance, solvent resistance, acid resistance, adhesion, and electrical properties of the resist film can be obtained.
