PURPOSE:To obtain daily necessaries, constructed from a material impregnated with a required ink capable of changing color thereof with a required moisture, etc., useful as toilet paper for humans or animals, sand for pets, etc., and capable of qualitatively or quantitatively sensing pH, proteins, etc., in urine and testing physical conditions. CONSTITUTION:The objective daily necessaries are obtained by sandwiching a sheet constructed from a material impregnated, coated, printed, etc., with a required ink capable of changing color thereof with a required moisture between a sheet composed of a nonwoven fabric such as rayon through which a liquid passes and a sheet composed of a synthetic resin having properties without passing a liquid therethrough as, e.g. a sheet for pets. Furthermore, the required ink uses phenolphthalein, etc., as a pH testing agent for urine, tetrabromophenol blue, etc., as a protein testing agent and glucose oxidase, etc., as a glucose testing agent. |
