JOURNAL FREE ACCESSOptical second harmonic generation (SHG) at various kinds of interfaces and at molecular thin films are currently of much interest in terms of its surface specificity and its time resolution. As a tool for the surface analysis the SHG method is quite promising in the field of surface science, electrochemistry and molecular engineering. Fundamental aspects of the surface SHG are briefly reviewed and some topics are presented which show the effectiveness and the versatility of the method. A novel approach based on the SHG-coherent interferometry for the elucidation of the molecular structures of LB films are also referred to.View full abstractDownload PDF (1151K) -

JOURNAL FREE ACCESSAn application of sodium alginate, a sodium salt of natural high-molecular carboxylic acid, to preparation of the J-aggregate of cyanine dyes has been examined. By spreading the ethanolic solution of four kinds of cyanine dyes over the sodium alginate films (SA films) and drying, the J-aggregate was easily formed as evidenced by appearance of sharp J-band. In comparison with luminescence properties of several dye aggregates in the cast films and Langmuir-Blodgett (LB) films, we could confirmthat SA films are the promising matrix to prepare the J-aggregate by a simple fabrication procedure.View full abstractDownload PDF (607K) -

JOURNAL FREE ACCESSIn February 1990, Fuji Photo Film Company intrduced a new color reversal film named Velvia having an ISO speed of 50. This film provides brilliant color images with far less noise as wellas much better sharpness than its predecessor.
In the present report, we will describe the technologies and features of Velvia.View full abstractDownload PDF (1006K) -

JOURNAL FREE ACCESSROSET compounds are able to release a wide range of photographic useful groups by a novel ring opening mechanism which is triggered by an electron transfer. They can be applied to various photographic systems with excellent characteristics as releasing compounds. Examples of applications to the photothermographic color hardcopy system and to the graphic arts system are described.View full abstractDownload PDF (793K) -

JOURNAL FREE ACCESSTwo advances occurred in the field of magenta coupler technology in recent 20 years. One is the progress of two equivalent pyrazolone couplers. The other is the appearance and realizationof pyrazolotriazole magenta couplers, which improve magenta hue and yellowish heat and light stain.
In this review are described characteristics of these two types of magenta couplers as well as functions of some additives which assist to realize exellent aspects of these couplers.View full abstractDownload PDF (737K) -

JOURNAL FREE ACCESSPractically all cyan couples are either phenols or naphthols which react with oxidized color developers to produce indoaniline dyes. However, these dyes generally have undesirable hue and poor heat stability. Although a distinct improvement of heat stability has been achieved in color paper by attaching certain substituents to the phenol, hue has not been significantly improved in any color photographic materials by manipulating phenol or naphthol ring substituents. It has therefore been necessary to investigate and develop new classes of cyan couplers for the improvement of both the hue and heat stability of cyan dyes. In searching for these new classes of cyan couplers, we first investigated, 5, 5- and 5, 6-ring fused heterocyclic compounds for use as cyan couplers in color paper. This first class of experimental compounds produced cyan dyes with both desirable hue and good heat stability. The second class of experimental compounds studied as cyan couplers for color negative film, that were also not naphthols but did contain naphthalene ring, did not exceptionally improve hue. However, the compounds produced a considerable improvement in heat stability.View full abstractDownload PDF (745K) -

JOURNAL FREE ACCESSWater soluble filter dyes are used in color negative paper in order to improve photographic sharpness. Several characteristics are required to perform this task. One of these important features is that the filter dyes have to absorb radiation in the region of the spectrum where the sensitized dye absorbs right. Second one is that the filter dyes must be decolored rapidly during processing. In order to meet these requirements, pyrazoloneoxonol dyes have been used as the filter dyes in color negative paper. These dyes are attacked by nucleophiles and are decolored. In this paper, I would like to show the relationship between the substituent's σ p values and wavelength, decoloring time of the filter dyes. I also show new oxonol dyes for photographic materials bliefly.View full abstractDownload PDF (703K) -

JOURNAL FREE ACCESSAcyl-hydrazides nucleating agents promotes high contrast and high photographic speed in the black and white negative films. Such nucleating agents have been used in graphic arts films since 1984. Now, we are interested in these acyl-hycdrazides as a new class of imagewise releaser of a photographically useful group or a new redox compound.
This article describes some kinetic studies concerning with the oxidation reaction followed by hydrolysis of acyl-hydrazide derivatives and also some properties of the key reaction intermediate. New application of acyl-hydrazide compounds to the developer inhibitor releaser (DIR) in the micro-area inhibition technology (MAI-Technology) of Fuji Super Grandex graphic arts materials, is also reviewed.View full abstractDownload PDF (2482K)
