    摘要： A polymerizable composition for polythiourethane optical materials comprising a compound represented by the general formula (1), M(L)n  (1) wherein, in the formula, M is Al, Fe, Cu, Zn, Zr or Bi; L is a dithiocarbamic acid group, a sulfonic acid group, a mono- or di-alkyl phosphoric acid ester group, a substituted acetylacetonato group or a halogen; and n is an integer of 1 to 5, one or two or more isocyanates selected from the group consisting of isocyanate compounds and isothiocyanate compounds, and one or two or more active hydrogen compounds each having a mercapto group. The compounds represented by the general formula (1) exhibit catalytic activity equal to or superior to that of organotin catalysts having been employed as catalysts for the production of polythiourethane optical materials from the past, and have high safety. Further, the thus obtained polythiourethane resins satisfactorily meet the property requirements for optical materials, in particular, excelling in weather resistance. Therefore, the proposed catalysts are available as novel catalysts replacing the organotin catalysts.

    摘要： Stable organosiloxane coating compositions that provide transparent, abrasion-resistant, chemical-resistant, low-tack, and water-washable anti-fog coatings when cured, are described herein. The coating compositions comprise an epoxy functional alkoxysilane, a tetrafunctional alkoxysilane, an alkoxysilyl functional polymer having polyethylene oxide segments, an alkoxysilyl functional cationic surfactant, and a carboxylic acid functional compound. Articles coated with the coating compositions, processes for coating substrates with the anti-fog coating compositions, and processes for making the coating compositions are also described herein.
