摘要

A dry type analysis element for detecting a specific constituent in a liquid is provided. The dry type analysis element comprises a light-transmissive support having thereon at least one water-penetrative layer, at least one of said water-penetrative layer(s) containing a composition capable of interacting with said specific constituent in said liquid, wherein said composition contains a leuco dye comprising at least one compound selected from the group consisting of compounds represented formula [I] and salts of these compounds wherein R<1> represents a substituted or unsubstituterd aryl group, R<2> represents a substituted or unsubstituterd alkyl group, and R<3> represents a substituted or unsubstituterd aryl group, and said leuco dye is dissolved in a hydrophobic solvent to form a solution that is contained in said water-penetrative layer as a dispersion in a hydrophilic medium.
