ジャーナル フリーPhotoelectrochemical reactions are defined as the electrochemical processes where the electronically excited states take part. Photoelectrochemical reactions are divided into two cases. The first one is the case in with the excitation of electrons in the electrode itself plays an essential role in the electron transfer process. The second one is the case where the excited species in the solution take part in the electrode process. Studies on these two fields are reviewed. The latter case with the semi-conductor electrode is particularly interesting in relation with the photographic spectral sensitization. Photoelectrochemical process with semi-conductor electrodes such as TiO2 and ZnO can be spectrally sensitized with dyes. Emphasis is laid on the close correlation between the spectral sensitizations of photoelectrochemical process and photographic process with AgBr.抄録全体を表示PDF形式でダウンロード (1028K) -

ジャーナル フリーRelations between the film-clearing time and the minimum time required to complete the processing in monobaths containing thiosulfate and thiocyanate as fixing agents have been investigated. It has been found that, in monobath processing, developing is always finished within the film-clearing time and fixing is complete at the time or above. Therefore, the minimum time for the complete monobath processing may be determined at the minimum time required to complete the fixation. The minimum time to complete the fixation can't be estimated by the measurement of the film-clearing time when thiocyanate is used alone or at higher ratio (over 50 mole %), but it can be estimated when thiosulfate is employed alone or at higher ratio (50 mole % or above). In most of the monobaths commonly used, since thiosulfate is employed alone or at higher ratio as fixing agents, the minimum time for the complete monobath processing may be probably estimated by measuring the film-clearing time.抄録全体を表示PDF形式でダウンロード (1005K) -

ジャーナル フリーIncrease in sensitivity and improvement of linearity for the photoresist hologram by the postexposure method are analytically studied. It becomes clear that the experimental values agree with the theoretical one approximately.
Besides, the characteristics of the replica hologram by embossing method is experimentally studied.
In this result, it is found that the replica hologram is copied perfectly even in deep grooves.抄録全体を表示PDF形式でダウンロード (3463K) -

ジャーナル フリーNew fixing agents were prepared by the reaction of thiocyanate and acid salt of inorganic compound such as sodium hydrogen sulfite, sodium hydrogen carbonate, and sodium hydrogen sulfate in the presence of acid or salt.
The reaction was carried out between 65 and 75°C for about 2.5 hours.
The agents were stable to light and humidity, and the hygroscopicity of the agents was about 20-30% less than that of thiocyanate.
The fixing property of agents was compared with thiosulfate. The fixing time of the agents was much shorter than that of thiosulfate.
Among these agents, the clearing time was reduced in the order of nNH4SCN·NaHSO4<nNH4SCN·NaHSO3<nNH4SCN·NaHCO3.
The agents were found to be useful as a rapid fixing agent for silver halide emulsion.抄録全体を表示PDF形式でダウンロード (651K) -

ジャーナル フリーIt has been presented in previous papers that the adhesive power between amorphous sulfur and the powder is changed by photopolymerization of cyclo-octa sulfur. In addition, the photopolymerization reaction was spectrally sensitized with Michler's thioketone (4, 4'-tetramethyldiamino thiobenzophenone).
Based on the above facts, new photo-imaging systems using amorphous sulfur layer are designed.
System A) Image exposure on the sulfur layer → washed off the unexposed sulfur by a organic solvent → development by powder → fixing by heat
System B) Image exposure on the sulfur layer → contacting the sulfur layer onto the transfer sheet and heating for transfer of the unexposed sulfur → powder development for both sheets → fixing by heat
System C) Image exposure on the sulfur layer → powder development → fixing by heat
System D) Image exposure → dipping into toluene solution of sulfur to aggregate the sulfur from the solution onto the unexposed area (formation of light scattering image)→ powder development → fixing by heat
In this paper, details of these imaging systems and the behavior of powder development will be described.抄録全体を表示PDF形式でダウンロード (3599K)
