    摘要: A retroreflective film comprising a lamination of a first base layer having vacuum metallized hemispherical depressions on one surface thereof and a second layer having substantially hemispherical projections from the surface thereof formed from an optically transparent film wherein the first and second layers are arranged so that the hemispherical depressions of the base layer and the substantially hemispherical projections of the intermediate layer are concentrically arranged and the radius of the hemispherical depressions of the base layer is greater than the radius of the substantially hemispherical projections of the second layer. A laminate construction with matched opposing substantially hemispherical projections on the second layer is preferably provided with a third optically clear overlay film.

    摘要: A method for providing nylon substrates with a durable, adherent silver coating and product by electroless deposition from a plating bath comprising silver salt, ammonia, anionic surfactant, formaldehyde, and sufficient acid to bring the pH to about 8.49.4. The substrates are sensitized with stannic chloride solution.

    摘要: Polyfunctional ester oxazolidines of the general formula

    WHEREIN Z is a polyvalent alkylene, arylene, or alkenylene radical, R1 and R2 are hydrogen, alkyl, phenyl, or benzyl, X and Y are divalent (C2-C3)alkylene radicals, and N IS AN INTEGER EQUAL TO THE VALENCE OF Z, produced by means of a transesterification process are useful in preparing or formulating adhesives, caulks, lacquers, paints, varnishes, leather impregnants and moisture-cured coating systems.
