Heat sensitive recording material, recording sheets formed from heat sensitive recording material, and methods for forming images using heat sensitive recording material are provided. An exemplary heat sensitive recording material includes a color forming compound, a first non-phenolic color developer, and a second non-phenolic color developer.

Heat sensitive recording material with non-phenolic color developers

The presently claimed invention relates to a color developer, a process for its manufacture and its use as a component in heat sensitive recording material. The heat sensitive recording material is useful for thermographic printing.

Heat sensitive recording material, and color developer

Aqueous composition comprising a color former, a developer, and a binder, wherein (a) the weight ratio between the developer and the color former is in the range of from 1 to 5; (b) the binder comprises an acrylate binder, comprising acrylic acid and styrene, and at least one additional monomer selected from the group consisting of &#x3b1;-methyl styrene, ethyl acrylate and 2-ethylhexyl acrylate; and (c) the color former and/or the developer are present in an un-encapsulated form; a process for the preparation of these compositions, substrates coated with this composition and a process for its preparation, and a process for preparing a marked substrate using this composition.

Aqueous laser-sensitive composition for marking substrates

Storage-stable compositions comprising a color developer, an anionic dispersant and a thickening agent as well as heat-sensitive recording materials comprising such compositions, a process for its manufacture and its use.

Stable aqueous dispersions of colour developer

An improved process for the preparation of microcapsules consisting essentially of a wall material and a core material in condensing a melamine-formaldehyde precondensate and/or methyl ethers thereof in an aqueous dispersion of a water-insoluble core material and in the presence of an acrylic acid/acrylamide copolymer at acidic pH and at a temperature in the range of from 20&#xb0; to 100&#xb0; C., and hardening thereafter the melamine-formaldehyde precondensate to form the walls of the microcapsules at an elevated temperature, wherein the core material is dispersed in the precondensate/copolymer solution without initial partial condensation of the precondensate and copolymer and wherein the hydrophobe point of the precondensate and/or its methyl esters is less than 90&#xb0; C., as well as microcapsules, paper and pressure-sensitive recording material comprising such microcapsules.

Process for the preparation of microcapsules

New color developers, new mixture comprising it, its processes for preparation, heat sensitive recording compositions and materials comprising the novel developers and mixtures as well as their uses in heat sensitive recording materials.
