Abstract
Disclosed are an ink jet recording method, which can produce, on recording media, good images possessing good lightfastness, waterfastness, rubbing resistance/scratch resistance, and gloss, and a reaction solution and an ink composition for use in the ink jet recording method. After printing of an ink composition, the application of a first liquid to form a coating can improve the waterfastness, rubbing resistance/scratch resistance and gloss of records. The incorporation of a cationic emulsion containing sites possessing ultraviolet absorbing activity and/or photostabilizing activity into the reaction solution can improve the lightfastness of records.
Claims36
An ink jet recording method for recording with an ink composition, a first liquid containing at least polymeric fine particles and a second liquid containing a reactant which, upon contact with the ink composition, forms coagulate, said method comprising the steps of:
- (a) depositing the second liquid onto a recording medium;
- (b) depositing the ink composition onto the recording medium in a position where the second liquid has been deposited;
- and
- (c) depositing the first liquid onto the recording medium in said position.
A reaction solution for use in an ink jet recording method comprising the step of despositing a reaction solution, containing a reactant which, upon contact with an ink composition, forms coagulate, and ink composition onto a recording medium to perform printing,
- the reaction solution containing polymeric fine particles having a site possessing ultraviolet absorbing activity and/or photostabilizing activity, wherein the site possessing ultraviolet absorbing activity and/or photostabilizing activity is selected from the group consisting of aromatic monocyclic hydrocarbon, fused polycyclic aromatic hydrocarbon, heteromonocyclic and fused heterocyclic groups.
