New amino alkyl sulphonic acids have been synthesized, including some substituted derivatives and several peptide analogues containing the CO·NH group formed from aminoacid and amino alkyl sulphonic acid components. Peptide-like compounds containing the SO2·NH group were prepared from N-substituted taurine and esters of aminoacids. Theoretical aspects underlying the reactions involved are discussed
A compound serving as a dichroic pigment which has a maximum absorption wavelength in a range of 350 nm to 510 nm is represented by the following Formula (1):
In Formula (1), R
1
represents a hydrogen atom or a C1-C20 alkyl group; R
2
through R
4
are substituents which are not hydrogen atoms and each independently represent a C1-C4 alkyl group; n, m, and p are each independently an integer of 0 to 2; and Ar
1
represents a nitrogen-containing saturated heterocyclic group which is a 5 to 8-membered ring and in which (i) N is bonded to a phenylene group and (ii) at least one β-position is an oxygen atom or a sulfur atom.

Gas resistance of an image is evaluated by placing the image in a mixed gas atmosphere containing at least ozone and nitrogen dioxide. The mixed gas atmosphere is controlled such that the concentrations of ozone and nitrogen dioxide are not less than 75 ppb and not less than 150 ppb, respectively, and the mixed gas is continuously supplied to the surface of a sample bearing the image at a flow rate not less than 0.2 m/s and not more than 3.0 m/s.

An ink jet ink contains at least a coloring material and a specific water-soluble organic solvent and has both excellent color developability and excellent humidity resistance. The coloring material exhibits a small (9 or less) color difference ΔE value which is determined by a method including a series of specific steps and is represented as the square root of (L

. The specific water-soluble organic solvent has an evaporation rate X smaller than that of water and a moisture absorptivity Y, the values of X and Y satisfying the relation of Y≦2.8X+10. The content of the specific water-soluble organic solvent is 50 mass % or more of the total amount of water-soluble organic solvents contained in the ink.

Dispersionen hydrophober Substanzen in Wasser werden hergestellt, indem man die hydrophobe Substanz zusammen mit einem ionomeren Polyadditions- oder Kondensations-produkt in einem organischen, mit Wasser mischbaren Lösungsmittel oder einer Mischung des Lösungsmittels mit Wasser löst, Wasser zusetzt und das Lösungsmittel entfernt. Die so hergestellten Dispersionen werden mit Vorteil bei der Herstellung photographischer Aufzeichnungsmaterialien verwendet.
