摘要:
An object of the present invention is to provide a recording material or a recording sheet using, as a color-developing agent, a non-phenol-based compound good in color developing performance and the like. A compound represented by the following formula (I) is used as the color-developing agent: (wherein X represents CH2 or the like; R1 to R3 each independently represent a hydrogen atom, a halogen atom or the like; n1 and n3 each independently represent any integer of 1 to 5; two groups represented by R3 adjacent to each other on a benzene ring optionally bond to each other to form an optionally substituted 6-membered ring; and n2 represents any integer of 1 to 4).

A marking system comprises a substrate having a surface coated with a color-triggering developer and a deactivating ink composition; and a marking composition comprising at least one color precursor. At least one “non-color developing portion” of the surface is coated with both the color-triggering developer and the deactivating ink composition, and at least one “color-developing portion” of the surface is coated with the color-triggering developer and is not coated with the deactivating ink composition. Color development occurs at the color-developing portion(s) and does not occur at the non-color developing portion(s) upon application of the marking composition to the surface of the substrate.

An object of the present invention is to provide a recording material or a recording sheet that is excellent not only in whiteness of a background but also in storage property for a background and an image, and further has excellent dynamic sensitivity. In order to achieve the object, a phenol compound represented by Formula (I) [wherein R1 represents a hydroxyl group or a halogen atom, p represents 0 or an integer of 1 to 5, R2 and R3 each independently represent a hydrogen atom or a C1-C6 alkyl group, R4 represents a hydrogen atom, a C1-C6 alkyl group, an optionally substituted phenyl group or an optionally substituted benzyl group; and a bond shown with a wavy line represents E- or Z-form, or a mixture thereof] and having a color space b* of 10 or less, and preferably having brightness by Hunter of 75 or more, is used as a recording material.
摘要:
A copying sheet comprises a first layer comprising a micro-encapsulated solvent, and at least one micro-encapsulated color agent, which is soluble in the micro encapsulated solvent; and a second layer comprising at least one additional color agent. Upon an outer influence the micro-encapsulated solvent of the first layer may penetrate the second layer at a position where the outer influence is applied. The at least one additional color agent of the second layer is at least partially releasable by the micro-encapsulated solvent

摘要:
A process for preparing a copolymer latex comprising emulsion polymerizing an aliphatic conjugated diene monomer and other monomer copolymerizable therewith in the presence of a cyclic unsaturated hydrocarbon having one unsaturated bond in a ring, in which, preferably a monomer mixture which does not contain the aliphatic conjugated diene monomer is added after the addition of a monomer mixture containing the aliphatic conjugated diene monomer, or a part of a chain transfer agent is added after the addition of the monomers. This copolymer latex is useful as an adhesive composition, a paper coating composition, an adhesive composition for back-sizing carpets, an adhesive composition for rock fiber materials, a paper coating composition for gravure printing, and a color developing composition for a pressure sensitive copying paper.
摘要:
A process is described for producing neutral to alkaline color developer pigments for use in carbon-free transfer papers from an acid-activated smectic phyllosilicate and basically reacting chemicals. The process is characterized in that the acid-activated phyllosilicate with a layer structure which is essentially still intact is reactive without intermediate drying with the basically-reacting chemicals up to partial or complete decomposition of the amorphous silicic acid formed on the corners and edges of the phyllosilicate crystallites without significant re-exchange of the hydronium ions inserted between the layers of the phyllosilicate by alkali or earth alkali ions.The color developer pigments can be used in suspensions with concentrations from 30 to 50% by weight, preferably from roughly 38 to 48% by weight.
