Abstract: Provided is a UV-curable ink jet coating comprised of a copolymer or mixture of polyvinyl alcohol and polyethylene oxide, and a water-soluble polymer which can act as an electron and/or proton donor, preferably containing at least one carbonyl group. The entire mixture is UV cured once coated onto a substrate thereby creating a matrix due to crosslinking between the water soluble polymer and the polyvinyl alcohol/polyethylene oxide copolymer or mixture. The result is an ink receptive coating which will absorb many different ink jet inks very rapidly, while exhibiting high gloss. The ink jet medium thereby permits use with many different printers and inks.

Abstract: Disclosed are electrophotographic elements comprising a support having coated thereon a photoconductive composition comprising a photoconductor dispersed in a linear film-forming polyester resin having its terminal hydroxyl and carboxyl groups endblocked with aprotic groups. The aprotic groups reduce hydrogen bonding within the resin matrix, and enhance the flowability of the resin when heated. Electrophotographic elements utilizing polyester resin binders endblocked in accordance with the present invention possess improved fusibility as compared with similar electrophotographic elements containing equivalent but protic endblocked polyester matrices, and as a result can be readily developed by flash fusing. In addition, such electrophotographic elements containing polyester resin binders endblocked in accordance with the instant invention possess improved photographic speed, and often improved dark decay properties, as compared with electrophotographic elements containing protic endblocked polyester matrices.

The diazonium compound can itself concurrently function as the acid progenitor, e.g., when complexed with a Lewis acid. Upon imagewise exposure to light, acid catalyst is photochemically liberated, thus unblocking coupler molecules such that dye image forms under alkaline developing conditions only where the material has been irradiated.

Abstract: This invention relates to novel polyoxyalkylene polymers characterized by olefinic endblocking groups in which the olefinic double bond is in the alpha position and is incapable of isomerizing or shifting to the beta or any other position. The novel polymers readily undergo addition reactions with siloxanes containing SiH to produce novel siloxane-polyoxyalkylene block copolymers that are useful as foam stabilizers for polyurethane foams. The olefinic double bonds undergo little side reactions during such addition reactions and so the product is relatively free of materials other than the block copolymer.
