Abstract: Deep-colored fibrous articles, such as fabrics colored in a deep black shade, having on it surfaces a film coating of a resin mixture comprising at least two resins that are mutually miscible but incompatible and in phase-separated conditions. Color-deepening effect is augmented by forming pits and/or recesses and projections on the surfaces of the film coating by using resins different in solvent-solubility and eluting the resin having a larger solubility with a solvent. The above effect is further augmented by using resins different in plasma etching resistance and subjecting the formed film coating to a low-temperature plasma etching treatment. The plasma etching is effectively conducted by placing the fibrous article within a plasma sheath, preferably contacting with an antenna electrode. The deep color can be made abrasion resistant by further depositing an abrasion resistant resinous film on the pit-formed resinous film coating without filling up the pits.

Abstract: Process of producing metal-resin composite, and the composite resulting therefrom, are provided. The process comprises providing a solution or dispersion of a resin, for example, an epoxy resin, said solution or dispersion having dispersed therein at least one particulate metal compound, for example, an oxide, of the Group I A and II A metals of the Periodic Table, the amount of metal compound being 1-500 parts by weight per 100 parts by weight of resin, then coating the solution or dispersion on a metal substrate and heating the coated substrate to evaporate the solvent for the resin and cure the resin. The resultant metal-resin composite is corrosion resistant, especially under acidic conditions, since the resin layer having the Group I A or II A metal compound dispersed therein serves to control the pH on the surface of the metal substrate to within the range of from 4 to 12 under acidic conditions in the atmosphere surrounding the metal-resin composite.

Abstract: A noise control apparatus for reducing a sound volume of a noise propagating from a noise source such as a railroad includes a sound arresting wall placed apart from the noise source. Means for shifting in phase and refracting the acoustic wave of the noise is disposed at substantially the top of the noise arresting wall.
