Abstract: The present invention relates to a composite formed article, comprising a formed article (A) and a rubber- or gel-like cured product (B), wherein the rubber- or gel-like cured product (B) is obtained by curing an active energy ray-curable composition. The present invention also relates to a forming method for producing a composite formed article, comprising injecting the curable composition (C) into a cavity in the formed article (A) and then curing the curable composition (C) by exposure to active energy rays to give the rubber- or gel-like cured product (B). The method aims to provide a composite article that combines the functionalities of each material without deteriorating the shape or performance of either material in the composite article.

Abstract: The present invention provides a novel photocurable composition containing an organic polymer having an epoxy group and/or oxetane group-containing silicon group at an end and a cationic photoinitiator. For example, the photocurable composition contains an organic polymer (A) having an epoxy group and/or oxetane group-containing silicon group at an end, and a cationic photoinitiator (B), the organic polymer (A) being produced by addition reaction between an organic polymer terminated with an unsaturated group and a hydrosilane compound having an epoxy group and/or an oxetane group.

Abstract: The present invention provides an organic polymer produced by selectively and quantitatively introducing a plurality of epoxy-containing silicon groups in the ends of any one of various organic polymers. The present invention also provides a process for easily producing the polymer, in which deterioration of polymers during the introduction of epoxy groups does not occur, or no labor for purification or the like due to the generation of by-products is required. For example, the organic polymer having epoxy-containing silicon groups at its ends is produced by addition reaction between an organic polymer having unsaturated groups at its ends and a hydrosilane compound having an epoxy group.

Abstract: There is provided a method of treating environmental stress due to the adverse effects of tobacco smoke and automobile exhaust gases. The method of treatment comprises applying to the skin a liniment composition containing one or more ingredients selected from among a group consisting of sulfur containing amino acids, metabolic intermediates of sulfur containing amino acids, tannin and vitamin C and its derivatives. A preferred sulfur containing amino acid is glutathione and preferred metabolic intermediates of sulfur containing amino acids are thiotaurine or hypotaurine. Also, hydroxycarboxylic acid or its derivatives can advantageously be added to this liniment composition to treat environmental stress.

Abstract: A contact lens comprising a lens substrate in shape of a lens which comprises a triorganovinylsilane based polymer, said lens substrate having a hydrophilic polymeric chain grafted onto the surface thereof. This contact lens is not only excellent in oxygen permeability, mechanical strength, dimensional stability, vision correcting ability, staining resistance and handleability, but also good in affinity with eyes due to good hydrophilic property possessed by the surface, which can be worn continuously for a long time.
