Description
現在のところベンゾフェノンが、その優れた表面硬化、低黄変、および優れた相溶性のため、紫外線(UV)硬化型オーバープリントニスの光開始剤として最も広く使用されている。これはまた、非常に安価で入手が極めて容易である。しかしながらベンゾフェノンは、その比較的強い臭気と並外れた移行性のため、ダンボールやプラスチック包装などの遮断包装さえも通し、印刷物から食品に抽出されることでも知られている。
nは1から6までの数で、
R3は水素原子、メチル基あるいはエチル基を表し、nが1より大きい場合はR3によって表される基、または原子は同じものあるいは互いに異なるものであり;
Aは化学式−[O(CHR2CHR1)a]y−、−[O(CH2)bCO]y−、または -[O(CH2)bCO](y-1)-[O(CHR2CHR1)a]-の基を表し、このとき:
R1および R2のうち一つが水素原子で、もう一つは水素原子、メチル基またはエチル基を表し;
aは1から2までの数であり;
bは4から5までの数であり;
Qは2つから6つのヒドロキシ基を有するポリヒドロキシ化合物の残基であり;またxは1より大きくQに含まれるヒドロキシ基の数以下の数であり;
xが1より大きく2以下の場合、yは1から10までの数であり;
あるいは、
xが2より大きい場合、yは3から10までの数である。
(a)少なくとも一つがエチレン不飽和モノマーあるいはオリゴマーである、重合可能な成分;および
(b)本発明に従う光開始剤。
特に好ましい化合物は、xが2であり、またyが1から10までの数である化合物である。
(HA)x-Q (III)
このとき、A、xおよびQは上記で定義されたものである。

比較例3の生成物の相溶性
比較例3の生成物の相溶性を、25% のアクリル酸エポキシオリゴマー(CN104A80 ex Cray-Valley)、およびグリセロールプロポキシレートトリアクリレート(GPTA)モノマーのバランスを備えた、8%のアミノアクリレート類似体(Actilane 715 ex Akcros Chemicals)を含む、通常のUV硬化型オーバープリントニス調合物で分析した。光開始剤レベル1、2、3、4、5、6、および7%を含むニスを用意し、加熱板攪拌器により、光開始剤をすべて溶解するのに要される100°Cで加熱した。室温で72時間おいた後、1%光開始剤含有のサンプル以外のすべてのサンプルの溶液中に光開始剤が戻った。

例9硬化性能の比較
上記の例および比較例に記述された方法で生成された、各々のテスト用光開始剤が、以下を含むUV硬化型ニス調合物中に調整された;
7% 光開始剤
8% アミノアクリレート類似体(Actilane 715 ex Akcros)
25% アクリル酸エポキシオリゴマー(CN104 A80 ex Cray-Valley)
60% 多官能モノマー、GPTA(グリセロールプロポキシレートトリアクリレート)
ニスの調合物を、ナンバー0 のKバー を使用してLenetaチャート上に印刷し、また出力140W/インチ(56W/cm)で作動する単一の中圧水銀灯を使用して、100m/minで硬化させた。良質の表面と完全な硬化を得るため、ランプの下のパスの数が記録された。結果の差異を明確に表すために、ランプの出力が意図的に最大出力の半分程度にセットされていることに注意されたい。結果は以下の表に示す。表1
例10反応速度の比較
(a) ベンゾイル安息香酸ベースの多官能光開始剤
両方の反応を並行して行った。両方の反応からサンプルを採取し、300nmで得られたクロマトグラムを酸性機能性ベンゾフェノン出発物質、単機能性エステル化生成物、および二機能性エステル化生成物の三つの異なった部分に分けて、HPLCにより分析した。各ベンゾフェノン酸タイプの二機能性エステル化生成物形成のグラフを、添付の図1に示す。
例11
光開始剤の接触移行分析
ニス調合物を以下の調合に基づいて製造した:
表2
例12光開始剤気相移行分析
硬化された印刷のサンプルを例11に説明されたのと同様に製造した。これらの50cm2のサンプルを、ペトリ皿におき、1.0gのTenaxでカバーした。これを180°Cまで10分間加熱し、ジエチルエーテルによりTenaxを抽出した後、HPLCによって存在する光開始剤を定量化した。
表3
表3の結果は、本発明の多官能光開始剤が、ベンゾフェノンやSpeedcure MBBなど、市販の単一機能性光開始剤に比べ、著しく低い気相移行を示す(検出されない)ことを明確に表している。比較例5もまたベンゾフェノンやSpeedcure MBBに比べ著しく低い気相移行を示している。これは検知はされているが、他の成分との共溶出現象により正確な定量化が不能であった。
