The present invention relates to metal-containing compositions with refractive indices of at least 1.5 comprising a metal-containing precursor unit (MU), a prepolymer unit (PU), and a catalyst or an initiator capable of inducing a combining reaction of ethylenically unsaturated functional groups of the metal-containing precursor unit and reactive functional groups of the prepolymer unit. In another embodiment, the composition comprises MU and a catalyst or initiator capable of inducing a combining reaction of the metal-containing precursor units. Both MU and PU contain additional functional groups, which may be selected to impart compatibility with each other and to produce optically clear films. The metal-containing compositions can be used to produce films or articles having a transmittance of at least 90% and index of refraction in the range of 1.5 to 1.8 in the 400-700 nm range of light and 1.5 to 2.4 in the 150-400 nm range of light.
[Constitution] A tricyclic heterocyclic compound represented by general formula (I) wherein R¹ and R² represent each hydrogen, lower alkyl, lower alkoxy, halogen or halogenated lower alkyl; R³ represents hydrogen or lower alkyl; R⁴ represents substituted phenyl or naphthyl; R⁵ represents hydrogen or lower alkyl; A represents lower alkylene; B represents -O- or -S-; and n represents 0 or 1. [Effect] It is excellent in the inhibition of acyl-CoA-cholesterol acyltransferase (ACAT) and is useful for treating or preventing arteriosclerosis.
The invention relates to an image support medium for creation of an aesthetic image that is an work or object for display. This support medium includes a polymer in an amount sufficient to enable the image to have at least one aesthetic element. In different embodiments, the image support medium is an image support stabilizer, the polymer is a synthetic absorbent or conductive polymer, or the polymer is a transparent or synthetic translucent polymer and a property of this transparent or translucent polymer is enhanced to facilitate the creation or preservation of the image by at least one stabilizer. The invention also relates to a method for preparing this image support medium. The method includes forming a reaction mixture comprising a monomer in an amount sufficient to provide or enable the image to have an aesthetic element, and processing the reaction mixture into a 2- or 3-dimensional shape.
