标 题:Oxonol compound, light-sensitive material and process for the synthesis of oxonol compound
发明人：NISHIGAKI JUNJI; DEGUCHI YASUAKI
权利人:FUJI PHOTO FILM CO LTD
摘要:An oxonol compound is represented by the following formula (I): in which Z is an atomic group that forms a cyclic amide ring; each of W1 and W2 independently is an atomic group that forms an acidic nucleus ring; and M is a cation. Other oxonol compounds, a light-sensitive material containing an oxonol compound and a process for the synthesis of an oxonol compound are also disclosed.

摘要:In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a Ï€-donor conjugated to a Ï€-acceptor through a Ï€-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product
发明人：MOLLS HANS-HEINZ; SCHIWY WILLY; HORNLE REINHOLD; NEBELING REINHARD
权利人:BAYER AG
摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
