ことを特徴とするものである。
ガラス基板と、
前記ガラス基板の一方の面の少なくとも一部に設けられた、上記硬化物からなる隠蔽層と、
を少なくとも備えることを特徴とする。
本発明の黒色感光性樹脂組成物は、(A)感光性樹脂、(B)光重合開始剤、(C)黒色顔料、および(D)フィラーを必須成分として含むものであり、(A)感光性樹脂として、結合部と、前記結合部に連結部を介して少なくとも2個の(メタ)アクリロイル基が結合したアクリレート化合物であって、連結部がカプロラクトン基、エチレンオキサイド基およびプロピレンオキサイド基からなる群より選択される少なくとも1種であり、一つの連結部中の炭素原子および酸素原子の総数が3~15個であるアクリレート化合物を含み、(D)フィラーとして、炭酸カルシウムを含むものである。以下、本発明の黒色感光性樹脂組成物を構成する各成分について詳細に説明する。
本発明の黒色感光性樹脂組成物に含まれる(A)感光性樹脂は、結合部と、前記結合部に連結部を介して少なくとも2個の(メタ)アクリロイル基が結合したアクリレート化合物であって、連結部がカプロラクトン基、エチレンオキサイド基およびプロピレンオキサイド基からなる群より選択される少なくとも1種であり、一つの連結部中の炭素原子および酸素原子の総数が3~15個であるアクリレート化合物を含む。このような特定のアクリレート化合物を感光性樹脂として用い、フィラーとして後記する炭酸カルシウムと併用することにより、カーボンブラックを含む黒色感光性樹脂組成物であっても、隠蔽性を維持しながら、絶縁性とガラスへの密着性とを向上させることができる。この理由は明らかでないが、黒色感光性樹脂組成物は、露光時に深部まで光が届きにくくガラス基板との密着性が不十分となり易いが、上記したような特定のアクリレート化合物を感光性樹脂として使用することによりガラスとの密着性を向上させることができると考えられる。
光重合開始剤としては、具体的には例えば、ビス-(2,6-ジクロロベンゾイル)フェニルフォスフィンオキサイド、ビス-(2,6-ジクロロベンゾイル)-2,5-ジメチルフェニルフォスフィンオキサイド、ビス-(2,6-ジクロロベンゾイル)-4-プロピルフェニルフォスフィンオキサイド、ビス-(2,6-ジクロロベンゾイル)-1-ナフチルフォスフィンオキサイド、ビス-(2,6-ジメトキシベンゾイル)フェニルフォスフィンオキサイド、ビス-(2,6-ジメトキシベンゾイル)-2,4,4-トリメチルペンチルフォスフィンオキサイド、ビス-(2,6-ジメトキシベンゾイル)-2,5-ジメチルフェニルフォスフィンオキサイド、ビス-(2,4,6-トリメチルベンゾイル)-フェニルフォスフィンオキサイド等のビスアシルフォスフィンオキサイド類;2,6-ジメトキシベンゾイルジフェニルフォスフィンオキサイド、2,6-ジクロロベンゾイルジフェニルフォスフィンオキサイド、2,4,6-トリメチルベンゾイルフェニルフォスフィン酸メチルエステル、2-メチルベンゾイルジフェニルフォスフィンオキサイド、ピバロイルフェニルフォスフィン酸イソプロピルエステル、2,4,6-トリメチルベンゾイルジフェニルフォスフィンオキサイド等のモノアシルフォスフィンオキサイド類;フェニル(2,4,6-トリメチルベンゾイル)フォスフィン酸エチル、1-ヒドロキシ-シクロヘキシルフェニルケトン、1-[4-(2-ヒドロキシエトキシ)-フェニル]-2-ヒドロキシ-2-メチル-1-プロパン-1-オン、2-ヒドロキシ-1-{4-[4-(2-ヒドロキシ-2-メチル-プロピオニル)-ベンジル]フェニル}-2-メチル-プロパン-1-オン、2-ヒドロキシ-2-メチル-1-フェニルプロパン-1-オン等のヒドロキシアセトフェノン類;ベンゾイン、ベンジル、ベンゾインメチルエーテル、ベンゾインエチルエーテル、ベンゾインn-プロピルエーテル、ベンゾインイソプロピルエーテル、ベンゾインn-ブチルエーテル等のベンゾイン類;ベンゾインアルキルエーテル類;ベンゾフェノン、p-メチルベンゾフェノン、ミヒラーズケトン、メチルベンゾフェノン、4,4’-ジクロロベンゾフェノン、4,4’-ビスジエチルアミノベンゾフェノン等のベンゾフェノン類;アセトフェノン、2,2-ジメトキシ-2-フェニルアセトフェノン、2,2-ジエトキシ-2-フェニルアセトフェノン、1,1-ジクロロアセトフェノン、1-ヒドロキシシクロヘキシルフェニルケトン、2-メチル-1-[4-(メチルチオ)フェニル]-2-モルフォリノ-1-プロパノン、2-ベンジル-2-ジメチルアミノ-1-(4-モルフォリノフェニル)-ブタノン-1、2-(ジメチルアミノ)-2-[(4-メチルフェニル)メチル)-1-[4-(4-モルホリニル)フェニル]-1-ブタノン、N,N-ジメチルアミノアセトフェノン等のアセトフェノン類;チオキサントン、2-エチルチオキサントン、2-イソプロピルチオキサントン、2,4-ジメチルチオキサントン、2,4-ジエチルチオキサントン、2-クロロチオキサントン、2,4-ジイソプロピルチオキサントン等のチオキサントン類;アントラキノン、クロロアントラキノン、2-メチルアントラキノン、2-エチルアントラキノン、2-tert-ブチルアントラキノン、1-クロロアントラキノン、2-アミルアントラキノン、2-アミノアントラキノン等のアントラキノン類;アセトフェノンジメチルケタール、ベンジルジメチルケタール等のケタール類;エチル-4-ジメチルアミノベンゾエート、2-(ジメチルアミノ)エチルベンゾエート、p-ジメチル安息香酸エチルエステル等の安息香酸エステル類;1,2-オクタンジオン,1-[4-(フェニルチオ)-,2-(O-ベンゾイルオキシム)]、エタノン,1-[9-エチル-6-(2-メチルベンゾイル)-9H-カルバゾール-3-イル]-,1-(O-アセチルオキシム)等のオキシムエステル類;ビス(η5-2,4-シクロペンタジエン-1-イル)-ビス(2,6-ジフルオロ-3-(1H-ピロール-1-イル)フェニル)チタニウム、ビス(シクロペンタジエニル)-ビス[2,6-ジフルオロ-3-(2-(1-ピル-1-イル)エチル)フェニル]チタニウム等のチタノセン類;フェニルジスルフィド2-ニトロフルオレン、ブチロイン、アニソインエチルエーテル、アゾビスイソブチロニトリル、テトラメチルチウラムジスルフィド等が挙げられ、これらは1種を単独で用いてもよく、2種以上の混合物として用いてもよい。
黒色顔料は、無機顔料であっても、有機顔料であってもよく、例えば、カーボンブラック、四三酸化鉄、黒酸化チタン、銅マンガンブラック、銅クロムブラックおよびコバルトブラック等の無機顔料、並びにシアニンブラックおよびアニリンブラック等の有機顔料が挙げられ、これらは1種を単独で用いてもよく、2種以上の混合物として用いてもよい。また、赤、青、緑、黄色等の顔料を混合し黒色とした顔料混合物も黒色顔料に含まれる。また、黒色顔料は、本発明の効果を阻害しない範囲内で、他の顔料や染料などの着色剤を併用しても良い。
本発明の黒色感光性樹脂組成物は、フィラーとして炭酸カルシウムを含む。上記したように、黒色感光性組成物は露光した際の深部硬化が不十分であるという問題を有するものの、本発明においては、感光性樹脂として、上記した変性多官能(メタ)アクリレート化合物を使用し、フィラーとして、炭酸カルシウムを使用することにより、隠蔽性を維持しながら、ガラスへの密着性や絶縁信頼性を向上させることができる。従来から、シリカ、タルク、硫酸バリウム等はフィラーとして、黒色感光性組成物に添加されることがあったが、上記した特定の変性多官能(メタ)アクリレートと炭酸カルシウムとを併用すると、予想外にも絶縁信頼性とガラス基板との密着性とを両立できることがわかった。その理由は明らかではないが、特定の変性多官能(メタ)アクリレートと炭酸カルシウムとの併用により、隠蔽性を維持できる程度のOD値を有する樹脂組成物とした場合であっても、絶縁信頼性とガラスへの密着性とを高い次元で両立できるものと考えられる。
黒色感光性樹脂組成物には、必要に応じてさらに、密着促進剤、酸化防止剤、紫外線吸収剤、分散剤などの成分を配合することができる。これらは、黒色感光性インクの分野において公知の物を使用することができる。また、シリコーン系、フッ素系、高分子系などの消泡剤およびレベリング剤の少なくともいずれか1種、イミダゾール系、チアゾール系、トリアゾール系等のシランカップリング剤、防錆剤、蛍光増白剤などのような公知慣用の添加剤類の少なくともいずれか一種を配合することができる。
OD値=-log10(T/100)
(式中、Tは透過率(%)を表す)
に基づいて算出することができる。
