In an integral multilayer analytical element which comprises a first nonfibrous porous layer, a second nonfibrous porous layer, and a fibrous porous layer superposed in this order to a water-impermeable light-transmissive support, the above three porous layers are integrally laminated to each other substantially closely by an adhesive disposed partially so as to form through microspaces to the degree not to interfere approximately uniform permeation of liquid, a reagent composition to produce an optically detectable change in the presence of an analyte is incorporated into at least one of said three porous layers, the improvement comprising that the void volume and the void volume per unit area of the first nonfibrous porous layer is less than a half of the void volume per the same unit area of the second nonfibrous porous layer. By using the analytical element of the invention, the analytical values of various analytes free from the hematocrit values of blood samples can be obtained from whole blood samples in the range of the hematocrit values of 25% to 55%.

A light-sensitive lithographic printing plate element suitable for the formation of negative and positive images, simultaneously, comprising a hydrophilic support having, in succession, a light-sensitive composition layer and a transparent cover film in which images for printing are formed by imagewise exposing through the cover film and peeling apart to remove, together with the cover film, the areas having a stronger adhesion to the cover film in the light-sensitive composition layer by utilizing the difference in adhesion to the support and to the cover film between the exposed areas and the unexposed areas of the light-sensitive composition layer, whereby the areas of the light-sensitive composition layer having a stronger adhesion to the support remain on the support, wherein the surface of the support adjacent the light-sensitive composition layer is treated with an aqueous solution containing at least one water soluble oxygen acid or water soluble oxygen acid salt selected from the group consisting of boric acid, boric acid salts, molybdic acids, molybdic acids salts, phosphoric acids, phosphoric acid salts, vanadic acids, vanadic acid salts, tungstic acids, tungstic acid salts, chromic acid, chromic acid salts, silicic acids and silicic acid salts.

Method of making a lithographic printing plate

A system for determining photo-chemical reaction heat evolved from a sample material irradiated with radiant energy comprises a calorimeter having a pair of sample holders connected to heat-leakage type thermo-electric elements which develop electric output signals proportionate to the amount of heat energy conducted therethrough. Both sample holders are initially irradiated with radiant energy before disposing the sample material thereon to heat the sample holders and thereby develop electric output reference signals. The amount of radiant energy being irradiated on at least one of the sample holders is then selectively adjusted to effectively compensate for any difference between the two reference signals. Then the sample material is mounted on at least one of the sample holders and both sample holders are irradiated with the adjusted radiant energy thereby enabling determination of the exothermic or endothermic heat value generated by the sample material due to the photo-chemical reaction heat evolved therefrom in accordance with the difference in the electric output signals developed by said thermo-electric elements.
