Abstract: PURPOSE: To make it possible to obtain a thin layer having a specific dyestuff concn. per unit area by dissolving lipophilic dyestuff and org. polymer into an org. solvent immiscible with water and spreading the soln. to the boundary between water/air, then evaporating the soln. CONSTITUTION: The monomolecular layer obtd. after evaporation of the org. solvent by dissolving the lipophilic dyestuff and the org. polymer into the org. solvent immiscible with water and spreading the soln. to the boundary between the water/air is transferred onto a solid layer carrier according to a Langmuir- Blodgett method. The lipophilic dyestuff is evidently embedded into the polymer in the monomolecular layer and is dissolved therein. Namely, the homogeneous mixture composed of the dyestuff and the polymer is obtd. as the monomolecular layer. As a result, the thin layer of the specific dyestuff concn. per unit area equal with respect to the fluctuation in the dyestuff concn. and the layer thickness (the number of the monomolecular layer) as well is reproducibly produced.

Abstract: PURPOSE: To attain the reading out of high sensitivity with slight electric power by reading out the information written into a specific polymer layer coating a metallic layer or semiconductor layer by surface plasmon. CONSTITUTION: The information written by image exposure by a laser beam 1 into the polymer layer 2 of a thickness of the layer of 0.1μm below with which the surface of a metallic layer 3 is coated is read out by the surface plasmon 6. The polymer layer 2 contains at least one kind of dyes at the prescribed concn. per unit surface area. The dyes are preferably lipophilic dyes which are soluble in an org. solvent and are dispersed uniformly into a polymer matrix. As a result, the memory of the information in the thin medium and the reading out at the high signal-to-noise ratio to the extent of allowing quantitative understanding are made possible.
