Title: Recording fluid and its production
Inventor: SUZUKI TAKEHIRO
IPC: C09D11/00
Filed: 1994-04-22
Abstract: PURPOSE:To obtain a water-base recording fluid which is used for ink jet recording and gives a water-resistant recorded material by dissolving an oil-soluble dye in an organic solvent to form an aqueous emulsion and then distilling off the organic solvent. CONSTITUTION:A solution of an oil-soluble dye in an organic solvent is mixed with water in the presence of a dispersion stabilizer to form an emulsion, and the solvent is then distilled off. The solvent is selected in respect of the capability of dissolving the dye; however, methyl ethyl ketone, acetone, methanol, toluene, etc., are suitable in particular. It is desirable to incorporate the dispersion stabilizer into the solution of the dye beforehand preferably at a weight ratio of the dye to the dispersion stabilizer of (5:1) to (1:5). As the dispersion stabilizer, e.g. a surfactant is used; however, the use of at least two kinds is desirable to improve the water resistance of a printed material. The distillation of the organic solvent from the emulsion is performed under a reduced pressure and, if necessary, by heating to thereby effect the phase inversion of the emulsion. Unlike the one based on a water-soluble dye, this recording fluid gives a recorded material free from blotting of the ink when the material becomes wet with water.

Abstract: PURPOSE:To enhance the gradation of a developed color image and the fixing sensitivity of a recording member by forming the 1st layer contg. a photoreducing agent, a hydrogen donor and a cobalt (III) ammine complex and the 2nd layer contg. a photooxidizing agent, a coupler, an acid and an adsorbent on a support. CONSTITUTION:On a support the 1st layer (visible light sensitive layer) is formed contg. a cobalt (III) ammine complex, a photoreducing agent and a hydrogen doner such as benzyl alcohol having active hydrogen. On the 1st layer the 2nd layer (ultraviolet sensitive layer) is formed contg. a photooxidizing agent, a leuco dye such as aminotriarylmethane, an acid such as toluenesulfonic acid or Lewis acid for accelerating coloring and an adsorbent such as zeolite mineral or its analogue for adsorbing NH3 formed by the decomposition of the complex, increasing the fixing effect and accelerating the coloring of the coupler. The resulting recording member is imagewise exposed and heated to reduce the complex in the exposed portion, generating NH3. This NH3 neutralizes the acid in the 2nd layer to inactivate the photooxidizing agent. The member is then irradiated with ultraviolet rays to oxidize the coupler in the visible light unexposed portion, thus allowing it to color.
