    • The present invention relates to a sterilization indicator using a chemical indicator that is useful for hydrogen peroxide plasma sterilization treatment and a sterilization packaging material for storing an article to be sterilized by plasma sterilization treatment that has an indicator area formed from the sterilization indicator provided thereon. The plasma-sterilization indicator according to the invention, which includes one or more compounds (A) selected from the group consisting of adsorption indicators and metal chelate-titration indicators, and an organic metal compound (B) and is irreversible in discoloration and higher in discoloration speed, allows definite judgment of whether or not an article in a sterilization packaging material was previously subjected to plasma sterilization treatment and thus is useful as a plasma-sterilization indicator. It becomes possible to increase or control the discoloration speed and obtain a superior display performance by adding additionally a polyvalent alcohol (C) to the plasma-sterilization indicator. The sterilization packaging material according to the invention is a sterilization packaging material for storing an article to be sterilized by plasma sterilization treatment, part of which is made of a gas permeable paper or nonwoven fabric and which uses the plasma-sterilization indicator according to the invention for the indicator area, and allows definite judgment of whether or not an article therein was previously subjected to plasma sterilization treatment without affecting the sterilization performance.
    • 本发明涉及使用可用于过氧化氢等离子体灭菌处理的化学指示剂的灭菌指示剂和用于通过等离子体灭菌处理存储具有由设置在其上的灭菌指示剂形成的指示剂区域的待灭菌物品的杀菌包装材料。 根据本发明的等离子体灭菌指示剂,其包括一种或多种选自吸附指示剂和金属螯合滴定指示剂的化合物(A)和有机金属化合物(B),并且在变色中不可逆,并且在 变色速度允许确定灭菌包装材料中的物品是否先前经过等离子体灭菌处理,因此可用作等离子体灭菌指示剂。 通过向等离子体灭菌指示剂添加另外的多元醇(C),可以增加或控制变色速度并获得优异的显示性能。 根据本发明的杀菌包装材料是一种灭菌包装材料,用于通过等离子体灭菌处理来存储待灭菌的物品,其一部分由透气纸或无纺织物制成,并且使用根据本发明的等离子体灭菌指示剂 对于指示器区域,并且允许确定其中的制品是否先前经过等离子体灭菌处理而不影响灭菌性能。
