Abstract: A heat-sensitive transferring recording medium comprises a base film, a heat melting ink layer provided on the under surface of the base film, and a conveyance improving layer provided on the upper surface of the base film, said conveyance improving layer comprising a material selected from the group consisting of compounds having a perfluoroalkyl group and ultraviolet ray-curing type resins.

Abstract: A heat-sensitive transferring recording medium comprises a base film, a heat melting ink layer provided on the under surface of the base film and a conveyance improving layer composed of a material selected from fatty acids, fatty acid derivatives, fatty alcohols, alkali metal salts of mono- or di-alkyl phosphoric acid esters of 8-18 carbon atoms, polyester copolymers, and other phosphoric acid esters.

Abstract: Improved distribution of the tin component of a hydrocarbon conversion catalyst also containing a Group VIII noble metal and halogen on a carrier is obtained by impregnation of the carrier with a solution of an acid amide or derivatives thereof and a soluble tin compound.

Abstract: A heat sensitive recording member is composed of a support and a heat sensitive layer overlying the support. The heat sensitive layer contains an iron salt of a higher fatty acid and gallic acid as color forming components, a stilbene series fluorescent dye as an unusual color forming inhibitor, and hydroxypropyl cellulose and hydroxypropyl methylcellulose.

Abstract: A multiple heat-sensitive copying medium comprises a double-sided heat-sensitive member having a heat-sensitive color forming layer, a good thermally conductive substrate and a heat-sensitive transferring layer containing a heat-sensitive color forming material.
