摘要： An anti-halation layer for photographic materials comprising at least one first binder which is swollen by an aqueous alkaline solution and comprises about 10 to about 25% by weight of alkyl acrylate units, 52 to 65% by weight of alkyl methacrylate units and about 18 to about 30% by weight of suitable acid monomer units, and at least a second binder agent which is soluble in an alkaline aqueous solution but which can withstand a strongly alkaline preliminary bath and is readily stripped away only at a successive rinsing operation.

摘要： A plurality of dielectric plates are disposed side by side to form a dielectric plate assembly and matching layers are respectively disposed adjacent to both end faces of the dielectric plates. A plane wave is incident on one of the matching layers perpendicularly thereto and passes through the dielectric plate assembly and are emitted from the other matching layer. Ratios b/a and a/.lambda..sub.0 (a being the distance between the centers of adjacent ones of the dielectric plates, b the thickness of each dielectric plate and .lambda..sub.0 the free space wave length of the electric wave) are selected so that the frequency characteristics of the phase difference between the electric field components of the plane wave respectively perpendicular and parallel to the dielectric plates, which are produced by the passage of the plane wave through the dielectric plate assembly, has a value of 90.degree. at two different values of a/.lambda..sub.0.
