    摘要: A mesh screen of polyester filaments for screen printing is subjected to a treatment with low temperature plasma in an atmosphere of a non-oxidizing inorganic gas to such an extent that a crosslinked layer having a thickness of 0.001 to 0.1 .mu.m is formed on the surface of the polyester filaments and the surface of the filaments is provided with protrusions and concavities having a diameter of 0.01 to 0.1 .mu.m in a distribution density of 1000 to 6000 per .mu.m.sup.2 of the surface area of the filament. The thus treated mesh screen is advantageously improved, with no adverse influences on the mechanical strength, in respect of the adhesion between the filament surface and a photosensitive resin composition applied to the mesh screen for photolithographic patterning. The plasmatreated mesh screen is also advantageous in respect of the decreased resistance against transfer of a printing ink through open meshes.

    摘要: The resin-impregnated composite prepreg based on a fabric material of an aromatic polyamide fiber is prepared by exposing the fabric material to low temperature plasma generated in an atmosphere of an inorganic gas, which is preferably oxygen or an oxygen-containing gaseous mixture, under a pressure of 0.5 to 5 Torr to such an extent that ruggedness of 0.01 to 0.5 .mu.m is formed on the surface and then impregnating the fabric material with an organic resinous binder. The adhesive bonding strength between the binder and the fiber surface can further be increased when the plasma-treated fabric material is brought into contact with an unsaturated compound polymerizable by free radical polymerization without contacting with air so as to form a graft-polymerized layer on the fiber surface.

    摘要: The invention provides a novel and efficient method for the improvement of the surface properties of a shaped article of a synthetic resin such as a vinyl chloride-based resin. In particular, the outstanding defective point of the plastic resin articles toward accumulation of static electricity on the surface is greatly reduced by the inventive method, in which the surface of the article is exposed to the low temperature plasma generated in a gaseous atmosphere containing an organic silicon compound followed, preferably, by contacting treatment with a halogen or a halogen compound such as hydrogen halides and halogen-containing organic compounds in a gaseous phase. The organic silicon compound in the gaseous plasma atmosphere is preferably diluted with a diluent gas which may be nitrogen, nitrogen oxides, ammonia or rare gases at a specified partial pressure.

    摘要: The invention provides a novel method for obtaining a shaped article of a vinyl chloride-based resin which is markedly insusceptible to the undesirable phenomenon of exudation or bleeding of the plasticizer and other additive ingredients contained therein on to the surface of the article. The method comprises formulating the resin composition for the fabrication of the shaped article with an epoxy compound containing, preferably, at least 2% by weight of the oxirane oxygen in the molecule in an amount of at least 0.05% by weight based on the vinyl chloride-based resin and irradiating the shaped article with ultraviolet light having a substantial energy distribution in the wavelength region of 200 nm or shorter. The shaped article obtained by the inventive method is remarkably insusceptible to the plasticizer bleeding even after prolonged outdoor exposure or irradiation with ultraviolet light having wavelengths longer than 290 nm.
