Estimating the term…
An ink jet recording method comprising the step of printing two solutions of a first solution and an ink composition is provided which, even in the case of printing on a recycled paper, can realize a good printed image, especially an image having no significant feathering and free from unevenness of printing and an image free from color bleeding. A first solution containing a polyvalent metal salt and/or a polyallylamine is used in combination with an ink composition containing an inorganic oxide colloid, and optionally an epoxy-containing compound. Specifically, the first solution is deposited onto a recording medium, and the ink composition is then deposited by ink jet printing to perform printing.
An ink jet recording method comprising the step of:
In a method for forming print on a recording medium by depositing an ink composition and a reaction solution onto the recording medium so that the reaction solution reacts with the ink composition to form the print with desired properties, said ink composition comprising a colorant and an aqueous solvent, said reaction solution comprising a polyvalent metal salt or a polyallylamine, the improvement comprising providing the ink composition with an inorganic oxide colloid and an epoxy-containing compound having a functional group reactive with an epoxy group, said inorganic oxide colloid being present in the ink composition in an amount sufficient to form the print with an improved rubbing resistance or evenness of printing as compared to the print formed with the ink composition without the inorganic oxide colloid.
