ジャーナル フリーThe recent progress on the mechanism of spectral sensitization in silver halide photography was reviewed from the viewpoints of (i) light abosrption, luminescence and aggregation of dyes, (ii) adsorption of dyes by AgX, (iii) electronic structures of dyes and AgX, (iv) other phenomena, (v) the mechanism of spectral sensitization, (vi) the mechanism of supersensitization, (vii) the mechanism of desensitization, and (viii) classification of photographic dyes.抄録全体を表示PDF形式でダウンロード (1112K) -

ジャーナル フリーThe relation of the developabilities of substituted benzenes with the positions of the highest occupied electronic energy levels (εh0) and the electron densities of their conjugated π-electron systems has been examined. The HMO calculations have shown that the εh0 of 1·2-, 1·4-, 1·2·3-, and 1·2·4- substituted benzenes [group I] are markedly higher than those of non-, 1-, 1·3-, and 1·3·5- substituted benzenes [group II], in the cases where electronegativities and bond lengths of substituents are small. While, on the contrary to the report by Lyalikov, there was no clear correlation between the developabilities and the π-electron densities at substituents of the substituted benzenes. This result suggest that the role of n-electrons is not important in the development process. Thus, it has been indicated that photographic development arises from the transfer of electrons at εh0 of conjugated π-electron systems of substituted benzenes of group I to exposed silver halide grains.抄録全体を表示PDF形式でダウンロード (618K) -

ジャーナル フリーThe changes of dislocation arrangements and latent image distribution in tabular silver bromide crystals in gelatin matrix were observed after deformation by an electron microscope at low temperature.
Majority of original crystals were found free from dislocations.
Dislocations were introduced by the application of pressure. These dislocation lines provided the centers of development. The surface latent image did not form in the dislocation-induced crystals.
The crystals deformed exclusively cracked along [110] or [211] directions. The formation of latent image specks seemed to occur most readily at those cleavage cracks. The increase or decrease in sensitivity of photographic emulsion by application of pressure might depend upon whether the cleavage cracks were formed on crystal surfaces or not.抄録全体を表示PDF形式でダウンロード (15439K) -

ジャーナル フリーThe effect of polyvinyl pyrrolidone (PVP) on the flocculation of negative silver iodide sol by potassium, barium and lanthanum nitrates was studied by means of the sol stability measurements. Four samples of PVP having different molecular weights were used. In the flocculation process, the stability of the sol in the presence of PVP is governed by the protecting and flocculating actions of PVP. Both these actions are pronounced in the case of high-molecular-weight PVP. The flocculating actin of PVP is observed at PVP concentrations near 3×10-4g/l, and it accelerates the flocculation of the sol by the electrolytes. The protecting action is remarkably observed at PVP concentration higher than 2×10-3g/l, and it increases with increasing PVP concentration. The influence of PVP on the electrophoretic mobility of the sol is very slight in the PVP concentration region of 0-2×10-3g/l.抄録全体を表示PDF形式でダウンロード (825K) -
