摘要： A microcapsule-containing water-base coating formulation comprises as essential components (a) microcapsules making use of a synthetic resin as a wall-forming material and (b) a reaction product obtained by polymerizing at least one water-soluble vinyl monomer (B) in the presence of a high polymer latex (A) having a glass transition point of 60.degree. C. or lower. The latex (A) and vinyl monomer (B) are used at a solid weight ratio of 3:97-90:10. The water-base coating formulation can provide a microcapsule-coated layer having significantly-improved pressure resistance and frictional stability without need for a stilt. The water-base coating formulation can be applied at a high speed, thereby making a significant improvement to the productivity of carbonless copying and/or recording paper.

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 microcapusles 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 temperature history indicator and its manufacturing method wherein the indicators are formed as chips, labels, tags or the like and accompanied with those goods or their packings which must be stored at a certain temperature or lower and when their storage temperature rises higher than the certain temperature over a not-permissible time period, this fact can be visibly shown by development or change of color caused by chemical matters in the indicator, characterized in that when temperature rises higher than a certain value, a hydrophobic organic compound enclosed in microcapsules melts and diffuses causing a dye-precursor and a color developer, which are prepared independently of the compound, to be contacted with each other to irreversibly achieve color development or change, that this color development or change system is rendered operative when the temperature rise continues to exceed a permissible time period, and that when the tops of the color development or change systems are coated with a transparent material, the arrangement of a bonding agent is improved neither to break those chemical compositions which cause the color development or change nor to lower their color developing function.

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.
