Abstract: A process for forming an ultrafine pattern on a surface of a substrate, which includes steps of irradiating the substrate surface with radiation modulated according to information to be patterned, subjecting the substrate surface to deposition with a material reactive or not with the substrate, and subjecting the substrate surface to etching if a substrate-reactive material is used for deposition. By this process, an ultrafine pattern can easily be formed with a high accuracy.

Abstract: A process for producing a photographic material, which comprises dispersing, in a solution of an organic resin, a material which is incompatible with the organic resin to form a dispersion, coating the resulting dispersion on at least one side of a support to form a coated layer, and then drying the coated layer, the material dispersed being a solid at ordinary temperature and in a liquid phase during the dispersing, whereby the coated layer when dried contains solid particles dispersed therein due to solidification of the dispersed material.The present invention also provides a photographic material obtained by the above process.

Abstract: A magnetic recording medium excellent in adhesiveness and surface property is produced by a process comprising treating the surface of a plastic substrate by glow discharge, then subjecting the substrate to a surface activating treatment and forming a magnetic metallic plating layer on the surface of the substrate by an electroless plating method.

Abstract: The present invention relates to a leader or trailer tape for a magnetic recording medium, which comprises a non-magnetic flexible support having a surface roughness of at least 0.15 .mu.m, at least one side thereof being optionally subjected to a surface activating treatment, and a transparent and electrically conductive metal oxide layer provided thereon.

Abstract: A photographic material comprising a support having thereon at least one photographic layer with the layer adjacent the support containing non-volatile or low volatile liquid droplets having smaller diameters than the thickness of the layer adjacent the support and a process for producing the photographic material.
