摘要： An aqueous suspension of a multivalent-metal-modified salicylic acid resin, which is suitable for use in the production of color-developing sheets for pressure-sensitive recording paper sheets, contains a specific multivalent-metal-modified salicylic acid resin at the first-mentioned resin. Fine particles of the specific multivalent-metal-modified salicylic acid is dispersed in an aqueous solution of a dispersant composed of at least one compound selected from the group consisting of:(a) water-soluble anionic high-molecular compounds composed of polyvinyl alcohol derivatives containing sulfonic acid groups in their molecules, and salts thereof,(b) acrylamide-modified polyvinyl alcohols, and(c) water-soluble anionic high-molecular compounds composed of polymers or copolymers comprising particular styrenesulfonic acid derivatives as their essential components.The aqueous dispersion is prepared by finely grinding the specific multivalent-metal-modified salicylic acid in the aqueous solution of the dispersant.

摘要： When obtaining microcapsules by covering a hydrophobic material with an aminoaldehyde polycondensation product as a wall-forming material in an acidic aqueous medium containing an anionic water-soluble polymer, a microcapsule slurry having a high solid content and low viscosity can be obtained by using as the anionic water-soluble polymer a multi-component copolymer consisting as essential monomer components thereof of at least three types of acrylic monomers selected respectively from (A) acrylic acid and/or methacrylic acid, (B) acrylonitrile and/or methacrylonitrile and (C) an acrylamidoalkylsulfonic acid and/or sulfoalkyl acrylate. Over a wide pH range, the microcapsule slurry obtained in accordance with this invention undergoes little viscosity changes and exhibits neither destruction of its dispersed state nor coagulating tendency. Resulting microcapsules have a sharp particle size distribution and are equipped with dense wall films.

摘要： A heat-sensitive recording unit formed by supporting a methine-type chromogenic reactant and oxidizing organic compound on a base. A color production sensitivity regulator may further be supported on the base. It is also feasible to add a quaternary ammonium salt, tertiary alkanol amine or water-soluble ion sequestering agent for avoiding undesirable color production of the methine-type chromogenic reactant. The ammonium salt, amine or ion sequestering agent may be added upon forming the methine-type chromogenic reactant into an aqueous suspension in order support the methine-type chromogenic reactant on the base.

摘要： Novel chlorinated 4-methylphthalic acids or anhydrides of the general formula ##STR1## wherein n is an integer of 1, 2 or 3, with the proviso that when n is 1, the chlorine atom is positioned at 3- or 5-position and when n is 2, the chlorine atoms are positioned at 3- and 5-positions. The new compounds are produced by dissolving 4-methylphthalic anhydride in concentrated sulfuric acid or fuming sulfuric acid to form a solution, and reacting the solution with chlorine at room temperature preferably in the presence of a catalytic amount of iodine, thereby to yield a crude product containing a mixture of chlorinated 4-methylphthalic acids. By subjecting the mixture to a thermal dehydration treatment in an inactive organic solvent, each of the chlorinated compounds may be isolated as its corresponding anhydride in the form of crystals.These chlorinated 4-methylphthalic anhydrides are valuable as intermediates for the preparation of dyestuffs or pigments.
