摘要:
Composition cosmétique comprenant des fibres rigides, sensiblement rectilignes, d'un polymère synthétique dans un milieu physiologiquement acceptable, dans laquelle le polymère est choisi parmi les polyuréthanes, les polyesters, les polymères acryliques, les polyoléfines, les polyamides non aromatiques et les polyimides-amides aromatiques. La composition peut être une composition de maquillage, une base de maquillage, une composition à appliquer sur un maquillage, dite encore « top-coat », ou bien encore une composition de traitement cosmétique, de soin, des fibres kératiniques. Plus particulièrement, l'invention porte sur un mascara. L'invention a trait également à l'utilisation de cette composition pour le maquillage des matières kératiniques, notamment des cils, sourcils et cheveux, ainsi qu'à un procédé de maquillage ou de soin cosmétique de ces dernières.

The present invention provides a polyimide resin, a resin composition, an adhesive solution, a film-state joining component, and an adhesive laminate film soluble in a solvent having excellent heat resistance and adhesion, capable of bonding and curing at relatively low temperatures. Specifically, the present invention provides a novel polyimide resin having low water absorption obtained by a reaction between tetracarboxylic acid dianhydride containing ester-acid dianhydride represented by the general formula (1): wherein X represents -(CH2)k-, or is a divalent group which comprises an aromatic ring, and k is an integer from 1 to 10; and aromatic diamine, where the resin composition and the film-state joining component which comprise a thermosetting resin with excellent adhesion using this resin are preferably used for flexible printed circuit boards, tapes for TAB (Tape Automated Bonding), composite lead frames, and lamination materials, or the like, and an adhesive laminate film suitable for coating of a superconductive wire rod.

摘要:
In a photoconductive element comprising a conductive support, e.g., an electrically conductive film, drum or belt on which a negatively chargeable photoconductive layer is formed, an electrical barrier layer is formed between the support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges but transports electrons under an applied electric field. The barrier layer of the invention transports charge by electronic rather than ionic mechanisms and, therefore, is not substantially affected by humidity changes. The barrier layer comprises a polyester-co-imide, polyesterionomer-co-imide or polyamide-co-imide having covalently bonded as repeating units in the polymer chain, aromatic tetracarboxylbisimide groups of the formula:
wherein Ar 1 and Ar 2 represent, respectively, tetravalent and trivalent aromatic groups of 6 to 20 carbon atoms.

摘要:
A negative birefringent film, useful in liquid crystal displays (2), and a method for controlling the negative birefringence of a polyimide film is disclosed which allows the matching of an application to a targeted amount of birefringence by controlling the degree of in-plane orientation of the polyimide by the selection of functional groups within both the diamine and dianhydride segments of the polyimide which affect the polyimide backbone chain rigidity, linearity, and symmetry. The higher the rigidity, linearity and symmetry of the polyimide backbone, the larger the value of the negative birefringence of the polyimide film.

A swash plate of a swash-plate compressor is subjected to sliding on shoes (19) and is required to have excellent seizure resistance and wear resistance under the dry lubricating condition. The swash plate (14) according to the present invention is provided with the surface-treated layer, i.e., the intermediate layer (7) consisiting of Cu, Sn or metal phosphate, and a sliding contact layer (8) consisting of MoS 2 and/or graphite and thermosetting resin.
