Disclosed is a coating composition appropriately usable for forming a hard coat film that is obtained by applying the composition onto a light-permeable member, such as a plastic lens having a high refractive index or a photochromic plastic lens having a color-developing function and a high refractive index, and hardening. This coating composition exhibits an extremely improved weather resistance (prevention of discoloration) while sustaining a high refractive index, a good scratch resistance and an excellent adhesiveness to an optical base. Specifically disclosed is a coating composition, comprising: titanium oxide-containing metal oxide microparticles (A) together with titanium oxide-containing metal oxide microparticles (B), provided that the titanium oxide-containing metal oxide microparticles (A) and the titanium oxide-containing metal oxide microparticles (B) have been selected through a specific light irradiation test and show different properties; an epoxy group-containing organosilicon compound (C) such as ?-glycidoxypropyltrimethoxysilane; water (D); an organic solvent (E) such as methyl alcohol; and a hardening catalyst (F) such as aluminum acetylacetonate or magnesium perchlorate, each in a specific amount.

A biaxially oriented polyester film, comprising a polyester (A) at least mainly composed of ethylene terephthalate and a polyether imide (B), having a single glass transition temperature, and having a refractive index of 1.60 to 1.80 at least in either the machine direction or the transverse direction, has excellent thermal dimensional stability, clarity and is easy to produce. It can be prepared by melt-extruding a polyester (A) at least mainly composed of ethylene terephthalate and polyether imide (B), to mold a resin sheet with a single glass transition temperature, and stretching the resin sheet at a ratio of 3.0 to 10 times in the machine direction and at a ratio of 3.0 to 10 times in the transverse direction.

An acrylic resin film material comprising at least a multilayer structure polymer with a particular structure prevent a molded item from being whitened during insert- or in-mold molding and meet the requirement for surface hardness, heat resistance, and transparency or matting performance for vehicle applications. It is also possible to use an acrylic resin film material exhibiting a difference of 30% or less between haze values as determined in accordance with the testing method of JIS K7136 (haze measurement method) after and before a tensile test where a test piece with a width of 20 mm is pulled under the conditions of an initial inter-chuck distance of 25 mm, a rate of 50 mm / min and a temperature of 23 DEG C. until an end-point inter-chuck distance becomes 33 mm as well as having a pencil hardness of 2 B or higher as determined in accordance with JIS K5400.

Provided is a method for improving the solubility of poorly-soluble substances used in pharmaceuticals, veterinary pharmaceuticals, quasi-drugs, cosmetics, food products, agricultural chemicals, and the like, without using large amounts of additives. The provided method is characterized in that fine particles of a calcium compound such as calcium phosphate or calcium carbonate are used to cover the surfaces of particles of a poorly-soluble substance used in pharmaceuticals, veterinary pharmaceuticals, quasi-drugs, cosmetics, food products, agricultural chemicals, or the like.

The present disclosure provides an industrially preferable, economical, and environmentally friendly method for producing a compound (C1) of formula (5), namely, a (4, 5-dihydroisooxazol -3-yl)thiocarboxamidine salt compound. The present disclosure relates to a method wherein: a reaction expressed by reaction formula (C2) is caused so as to produce a compound of formula (4) by reacting a compoundof formula (3) with a halogenation agent in the presence of a nitrile solvent, and the compound of formula (4) is subsequently reacted with a isothiouronium-forming agent, thereby producing a compoundof formula (5).

The invention of the present application addresses the problem of providing: a bronze alloy which has a lead-free composition and is imparted with high seize resistance and adhesive wear resistance enough to withstand fluctuating high-speed / high-surface-pressure sliding; and a sliding member. The bronze alloy according to the invention of the present application is characterized by being a metal structure which contains 8 to 15% by mass of Sn, 0.5 to 5.0% by mass of Bi, 0.5 to 5.0% by mass of Ni, 0.08 to 1.2% by mass of S and 0.5 to 6.0% by mass of Fe, with the remainder made up by Cu and unavoidable impurities, and has such an eutectoid structure that a fine flake-like copper-tin-based intermetallic compound is precipitated in alpha-copper, wherein an iron-nickel-based intermetallic compound and a copper-iron-based mixed sulfide are dispersed in the metal structure.

According to the present invention, there is provides a foldable heat radiation board, in which: a plurality of elongated and narrow plate-like members with fluid tube embedding grooves provided therein are combined with each other in a quadrangular plan configuration; fluid tubes are embedded in the embedding grooves; a heat radiation sheet is attached to the entire surface on the front surface side; a back surface material is attached to the entire or partial surface on the back surface side; a plurality of contact portions in which the end portions of adjacent plate-like members contact with each other are set as folding portions; and a fluid tube outlet opening portion in the end portion of one of the plate-like members and a fluid tube inlet opening portion in the end portion of the other of the plate-like members are provided so as not to oppose each other but to be shifted from each other, this portion being set as a fluid tube passage portion. With this construction, the number of construction elements (components) is reduced, the manufacturing process is easy to perform, folding is possible, buckling in the fluid tubes and the plate-like members and damages due to friction with the grooves provided in the plate-like members, do not occur at the time of packaging, storage, transportation, and installation, installation at the installation site is easy to perform, and the surface after the installation is finished flat.
