摘要： A magnetic recording medium is disclosed. The medium is comprised of a non-magnetic flexible support having a subbing layer coated thereon with a magnetic layer coated on the subbing layer. The subbing layer is comprised of a copolymer of a diolefin and a vinyl monomer. The subbing layer provides excellent adhesiveness between the support and the magnetic layer and can be produced without the use of organic solvents. Accordingly, the subbing layer can be economically produced without environmental pollution.

摘要： This invention discloses a heat sensitive recording material having a heat sensitive layer on a support; either of a color forming material or a developer which are contained in the heat sensitive layer is encased in a microcapsule. Since a plasticizer for a wall material of the microcapsule and a compound having an effect to depress the melting point of at least one member out of developers, a color forming reaction is carried out smoothly under a recording condition, therefore, a density of an obtained image is sufficient. Especially good results are obtained when a macromolecule substance selected from a group of polyurethane, polyurea, polyamide, polyester and polycarbonate is used as a wall material of the microcapsule. A coloring reaction assistant may be contained in any place of the heat sensitive layer.A preferable plasticizer can be selected from a group of phenols, alcohols, ureas, sulfonamides, carbamates and aromatic methoxy compounds.
