JOURNAL FREE ACCESSMolecular weight distribution of gelatins, such as limed ossein extraction series and IAG gelatins, were determined by gel permeation chromatography. The relationship between molecular weight distribution of these gelatins and physical properties, viscosity and jelly strength, were discussed. Chromatograms were fractionated based on α, β, and γ components. The higher molecular weight portions have an effect on viscosity. Jelly strength was related to the ratio of fα (α component) of limed ossein gelatin. It can be considered that molecular weight distribution of gelatin and pre-treatment of raw material are to some extent responsible for the physical properties of gelatin.View full abstractDownload PDF (1229K) -

JOURNAL FREE ACCESSTo estimate practical utility as colour couplers of ureido and hydantoinyl pyrazolones, absorption characteristics of azomethine dyes formed by the oxidative reaction of these compounds and CD-III were measured in various solvents.
It was concluded from the comparison of each absorption characteristic of ureido and amido pyrazolone azomethine dyes that monosubstituted ureido pyrazolone dyes showed unusual absorption characteristics due to the intramolecular six-membered hydrogen bonding.
3-Anilinopyrazolones having disubstituted ureido and hydantoinyl group on aniline moiety showed satisfactory properties as colour coupler in respect of the solubility in coupler solvent and the absorption characteristics of the dye formed from the chromogenic development.View full abstractDownload PDF (636K) -
