本発明は、感光性樹脂組成物及びこれを用いた感光性樹
脂組成物積層体(以下、単に「感光性フィルム」とよぶ
)に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a photosensitive resin composition and a photosensitive resin composition laminate (hereinafter simply referred to as "photosensitive film") using the same.

Time is short;
The present invention relates to an excellent photosensitive resin composition having a small peelable piece shape and a photosensitive film using the composition.

アルカリ現像型感光性フィルムとがあるが、コスト、作
業環境等の面からアルカリ現像型感光性フィルムが多く
使用されている。(Prior Art) Conventionally, in fields such as manufacturing of printed wiring boards and precision processing of metals, photosensitive resin compositions and photosensitive resin compositions obtained using the same have been used as resist materials for etching, plating, etc. Film is widely used. There are two types of photosensitive films: solvent-developable photosensitive films that are developed using chlorinated organic solvents and alkaline-developable photosensitive films that are developed using alkaline aqueous solutions. Alkaline developable photosensitive films are often used.

多く、使用に際して問題となることが多かった。エツチ
ング液には大別して。However, this alkali-developable photosensitive film has low resistance to etching, especially alkali etching, compared to conventional organic solvent-developable photosensitive films, and therefore has many limitations in processing and often causes problems in use. Broadly divided into etching liquids.
2種類有シ、1)酸性エツチング液2例えば、塩化第2
銅、塩化第2鉄、2)アルカリ性エツチング液。There are two types: 1) Acidic etching solution 2 For example, dichloride
Copper, ferric chloride, 2) alkaline etching solution.
例えば、アンモニアをベースとしたアルカリエツチング
液が多く使用されている。従来の有機溶剤現像型感光性
フィルムは、この2種のエツチング液に対し同等の耐性

性があるが、エツチング液である比較的強いアルカリエ
ツチング液に対し、耐性が十分でなくアルカリエツチン
グ液のpH,温度、エツチング時間等に極めて敏感であ
わ2作業条件の裕度が非常に狭いことが問題であった。For example, ammonia-based alkaline etching solutions are often used. Conventional organic solvent-developable photosensitive films exhibit equivalent resistance to these two types of etching solutions, but alkaline-developable photosensitive films use a high molecular weight material containing a large number of carboxyl groups as a polymer that imparts film properties. Because of this, it is resistant to weakly alkaline developers, but it is not sufficiently resistant to relatively strong alkaline etching solutions and is extremely sensitive to the pH, temperature, etching time, etc. of the alkaline etching solution. The problem was that the latitude for foam 2 working conditions was very narrow.
また、アルカリ現像型感光性フィルムは、有機溶剤現像

パターン形成後のレジストの剥離性が劣っていることも
問題とされていた。すなわち、有機溶剤現像型感光性フ
ィルムを使用した場合、そのレジストの剥離は一般的に
塩化メチレンのような溶剤で行なわれ、剥離片が細片と
なり。Another problem with alkali-developable photosensitive films is that they are inferior in resist removability after pattern formation by etching or plating compared to organic solvent-developable photosensitive resin compositions. That is, when an organic solvent developable photosensitive film is used, the resist is generally removed using a solvent such as methylene chloride, and the peeled pieces become fine pieces.

ンスが簡単である。一方、アルカリ現像型感光性フィル
ムを使用した場合、そのレジストの剥離は一般的に加温
した水酸化ナトリウム水溶液又は水酸化カリウム水溶液
によって行なわれるが。The printed wiring board is easy to clean, and the stripping solution or stripping machine is easy to maintain. On the other hand, when an alkali-developable photosensitive film is used, the resist is generally removed using a heated aqueous solution of sodium hydroxide or aqueous potassium hydroxide.
剥離片は細分化せず、いわゆる“ワカメ”状となう印刷
配線板に再付着し、また、剥離液のろ過による再生が困
難であることが作業上大きな問題となっている。The peeled pieces do not break into small pieces, but re-adhere to the printed wiring board in a so-called "seaweed" shape, and it is difficult to regenerate the peeling solution by filtration, which poses a major operational problem.

Thereafter, the alkali etching resistance was examined using two evaluation methods. To examine adhesion and non-biting, cellophane tape was applied to the photocured film, and this was quickly peeled off in the vertical direction (90° beer-off test) to check for peeling of the photocured film.
