    摘要: Color formers of the general formula ##STR1## in which --independently of one another-- R.sup.1 and R.sup.2 are hydrogen, halogen, alkyl, aralkyl etc.,Y.sup.1 and Y.sup.2 are alkyl, aryl, cycloalkyl or aralkyl,X.sup.1 is alkyl, alkenyl, cycloalkyl, aralkyl etc.,X.sup.2 is H, alkyl, alkenyl, cycloalkyl etc.X.sup.1 with X.sup.2 with the inclusion of the nitrogen atom carrying them can form a saturated or unsaturated 5- or 6-membered heterocyclic ring, andfurther isocyclic or heterocyclic rings can be fused with the rings A, B and C, upon incorporation in recording materials based on acid developers, show a particularly advantageous migration behaviour. Deep blue, green-blue, green, violet or red shades which have excellent sublimation and light fastness are obtained.

    摘要: Disclosed herein is a novel compound which is excellent in solubility to water around a neutral range, stable in an aqueous solution state for a long period of time, and high in coloring sensitivity with a stable coloring development, and is represented by the general formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same as or different from one another, represent lower alkyl groups, and X.sub.1 and X.sub.2 both represent --O(CH.sub.2).sub.n SO.sub.3 M in which M is a hydrogen atom, an alkali metal ion or NH.sub.4.sup.+, and n is an integer of 2-4, or either of X.sub.1 and X.sub.2 represents --O(CH.sub.2).sub.n SO.sub.3 M in whch M and n are the same meanings as given above and the other represents a hydrogen atom. This reagent is hardly susceptible of the influence of the serum components such as hemoglobin, bilirubin and so on due to its color having absorption on a longer wavelength side. Disclosed is also a method of quantitatively measuring an oxidative substance, particularly, hydrogen peroxide, by using this color test reagent.

    摘要: Disclosed is a pressure sensitive recording unit which comprises a single base web sheet and a methine-type dyestuff and an organic oxidizing compound both supported on the single base web sheet, or a combination of first and second base web sheets and the methine-type dyestuff and organic oxidizing compound supported individually on the first and second base web sheets. Such a recording unit includes for example a pressure sensitive recording unit formed in combination of (a) a back-coated topsheet (CB-sheet) making use of microscopic capsules containing a solution obtained by dissolving a methine-type dyestuff in a solvent having a high boiling point and (b) a front-coated undersheet (CF-sheet) carrying an organic oxidizing compound coated thereon. Also disclosed is a pressure sensitive recording unit which includes a base web sheet carrying thereon such a methine-type dyestuff together with a metal ion sequestering agent and/or alkanol amine.
