An organic board of the present disclosure has a resin component comprising at least one resin selected from the group consisting of an epoxy resin, a polyimide resin, a phenolic resin, an amino resin, a polyester resin, a polyphenylene resin, a cyclic olefin resin, and a Teflon (registered trademark) resin as the main component, and a non-resin component including at least one of an inorganic filler and a flame retardant, in which the non-resin component is dispersed in the resin component, at least a part of the non-resin component is agglomerated to form an aggregate, a part of the resin component forms a resin material part having a particle shape, the resin material part exists within the aggregate, or the resin component forms a matrix phase surrounding the aggregate, and there are voids at some interfaces between the resin component and the aggregate.

Regioselectively substituted cellulose esters having a plurality of pivaloyl substituents and a plurality of aryl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in films, such as +A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

Specifically, disclosed is an acrylic resin composition including, with respect to 100 parts by mass of an acrylic resin, from 0.1 to 8 parts by mass of a triazine-based UV absorber including 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[2-(2-ethylhexanoyloxy)ethoxy]phenol, wherein the acrylic resin used is an acrylic resin including at least 80 wt % of methyl methacrylate as a monomer component, and having a glass transition temperature of at least 80° C.

The present invention relates to the use of a fumigant barrier film for treating soil by fumigation, said film having, on at least one portion of the outer surface thereof or on at least one portion of the inner surface thereof or on at least one portion of the outer and inner surfaces thereof, at least one continuous self-adhesive or self-sticking or tackifying area. The present invention also relates to the method for sealing soil intended for fumigation treatment or in the process of fumigation treatment or which has been treated by fumigation, by covering said soil with a self-adhesive fumigant barrier film, as well as to a kit for fumigation treatment including at least one self-adhesive fumigant barrier film and at least one fumigant.

A composite structure comprising a resinous component that is adhered to a surface of a metal component is provided. The resinous component is formed from a polymer composition that comprises a polyarylene sulfide, inorganic fibers, and an impact modifier. The inorganic fibers have an aspect ratio of from about 1.5 to about 10.
