A resin article comprising a shaped body of a synthetic resin having a surface, and a coated resin layer covering the surface of the shaped body, said coated resin layer being made of an amino group-containing polymer and/or a polymer containing (meth) acrylate of (iso)cyanuric acid as a constituent unit and having a top surface, wherein the top surface of the coated resin layer is chemically converted to have an anti-static property by chemical reaction with a quaternary compound-forming reagent. Alternatively, a resin article having stable anti-static properties may comprise a shaped body of a synthetic resin covered with an anti-static coating layer made of a reaction product of at least one of an amino group-containing alkoxy silane, an amino group-containing alkoxy titanium compund, or an oligomer thereof, with a quaternary compound-forming reagent.

Resin article having anti-static property

Polypyrrole shaped material, process for production thereof, and

A photocrosslinkable substantially linear polyester polymer having sensitivity to visible light is provided which contains at least 10 mole %, based on the entire polymer, of units derived from a phenylenebis(.alpha.-cyanobutadienecarboxylic acid) and has a reduced viscosity of at least 0.2 dl/g. A typical use of the polymer is in making printing plates.

Visible light-sensitive polyester polymer and visible light-sensitive

Benzil-di[.beta.-(di-.beta.-methallylisocyanuryl)ethyl]ketal of the following structural formula: ##STR1## and other novel benzil ketal derivatives. The novel benzil ketal derivatives are characterized by having a structure in which an isocyanuryl-containing group is bonded to each of the two oxygen atoms of ketal. Because these compounds have a high decomposition or sublimation temperature and ability to initiate photopolymerization, they are useful as photopolymerization initiators in the production of photopolymerizable shaped articles from a molten blend of a photopolymerizable thermoplastic polymer composition.

Benzil ketal derivatives

Benzil-di-(.beta.-succinimidoethyl)ketal of the following structural formula ##STR1## and novel benzil ketal derivatives thereof. The novel benzil ketal derivatives are characterized by having a structure in which a 5- or 6-membered cyclic imidecontaining group is bonded to each of the two oxygen atoms of ketal. Because these compounds have a high decomposition or sublimation temperature and the ability to initiate photopolymerization, they are useful as photopolymerization initiators in the production of photopolymerizable shaped articles from a molten blend of a photopolymerizable thermoplastic polymer composition.
