Abstract: A layer forming method is disclosed which comprises the steps of supplying power of not less than 1 W/cm2 at a high frequency voltage exceeding 100 kHz across a gap between a first electrode and a second electrode opposed to each other at atmospheric pressure or at approximately atmospheric pressure to induce a discharge, generating a reactive gas in a plasma state by the charge, and exposing a substrate to the reactive gas in a plasma state to form a layer on the substrate.

Abstract: By carrying out a plasma discharge treatment for a support in which an image receiving layer comprising a void structure is formed, the void structure of the surface layer is subjected to hydrophilic treatment to enhance the water absorption capability of a recording media in the thickness direction (in the depth direction) and to enhance image receiving capability. Further, by making a portion more adjacent to the surface hydrophobic, an image disorder after receiving ink droplets is minimized. Still further, by continually carrying out an image receiving layer forming plasma treatment, it is possible to more efficiently produce an ink jet recording medium.

Abstract: An abrasive solid is composed of a resinous matrix and an abrasive material dispersed in the matrix to form a solid mass, whose resistance to cutting is from 2 kgf (19.6N) to 15 kgf (147N) so that the abrasive solid is severable into two with use of a knife, cutter or the like tool and highly effective to remove rust from any target article. Two or more of such abrasive solids each having these properties are consolidated to form an integral piece that can be trimmed into any desired shape so as to perform both the rough and smooth abrasion works for removal of rust, without using and changing any ordinary abrasive tools one after another.

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.
