Description
米国政府は、本発明における一括払いのライセンスと、限定された状況において、特許所有者が、「軽量および低コストの柔構造繊維」、米陸軍第一次中小企業技術革新研究補助金、契約番号DAAD16-03-C-0011の契約条件によって提供される妥当な条件で、他の者にライセンスを供与することを義務付ける権利とを有する。
本出願は、シリアル番号第61/167,409号を有し、2009年4月7日に出願した米国仮出願の優先権を主張するものである。本出願は、シリアル番号第12/652,670号を有し、2010年1月5日に出願した同時係属出願の一部継続である。
3光触媒+3O2→光触媒+1O2
アルミニウムフタロシアニンテトラスルホニルクロリド190(2g)を10mLのアセトン中に溶解した。超音波処理を使用することによって、染料の溶解を促進させた。炭酸カリウム(無水;>4当量、約1.3g)を染料溶液に加えた。結果として生じた混合物を室温で撹拌した。アミノプロピルトリエトキシシラン(Silquest A-1100、Momentive Performance materials、Inc.、North Greenbush、NY);2当量、0.91g)およびn-ドデシルアミン(2当量、0.76g)を、5mLのエタノール(200プルーフ)に混合すると、透明な溶液が生じた。この透明な混合物を、アルミニウムフタロシアニンテトラスルホニルクロリド溶液に、10分の時間内でゆっくりと滴加することによって、光触媒組成物192を調製した。追加のエタノール(5mL)を、光触媒組成物192溶液に加えた。結果として生じた光触媒組成物192溶液は、コーティング配合物中での使用の少なくとも2時間前から室温で激しく撹拌させておいた。
TABLE 4(表4)は、光触媒組成物192を用いた出願人のコーティング配合物を要約している。
実施例45の方法を利用した。処理された布帛を75℃(オーブン設定80℃)で13〜16分間乾燥させた。
本明細書中で上の実施例49において記載されているAATCC 100試験手順を用いて、この実施例50の処理された布帛を評価した。TABLE 5(表5)は、K. pneumoniaeおよび本明細書中ですぐ上に記載されている光触媒組成物192を含むコーティング配合物のバッチ番号1で処理された布帛を用いたAATCC試験結果を要約している。
