Sheet shaped detecting material for leakage check

Abstract

Abstract PURPOSE:To provide excellent adhesion with a body, whose leakage is checked, to ensure the sealing of a defective part and to detect the defective part accurately, by using an additive product, which is obtained by the reaction of gelatin and N-hydroxyimide ester compound as a base material. CONSTITUTION:For example, 2 mols of maleic anhydride is made to react with polyethylene glycol, whose number of additional mols is 141, and half ester is prepared. Then, two mols of N-hydroxysuccinimide is made to react with the half ester. Thus a bridging agent expressed by the Formula is prepared. An adhesive coloration layer, which is obtained by compounding a coloration agent into the bridging agent, is applied on a sheet shaped supporting body. Thus a sheet shaped detecting material can be obtained. In this way, adhesion with a body, whose leakage is checked, is made excellent, a defective part can be positively sealed and the defective part can be accurately detected.
