AI Technical Summary

Benefits of technology

The present invention provides an ink jet recording material with improved light-fastness. This is achieved by adding a compound represented by formula (I) to the ink jet recording material. The compound contains a nitrogen-nitrogen or nitrogen-oxygen bond, which links a divalent linking group to a five- or six-membered ring. The compound also contains at least two hydroxyl groups. The invention also provides an ink jet recording material comprising a support and at least one binder-containing ink-receiving layer, wherein the ink-receiving layer contains the compound. The compound helps to stabilize the ink jet recording material and prevent fading when exposed to light.

Problems solved by technology

It is difficult to satisfy them all at the same time.
A particular problem is the stability of the color densities of the finished color ink jet image when exposed to light for a longer period (“light-fastness”).

Preparation of the Coating Solution

[0093] To apply the light-stabilizing agent to ink jet print media, a coating liquid was prepared by adding 25 parts by solid weight of a 10% aqueous solution of compound Stabilizer 1 (ST1) (see list of stabilizers in the Detailed Description section) to 170 parts of water.

[0094] Coating and evaluation of the coated samples:

[0095] The coating solution was applied to a glossy porous media (Agfajet Universal Instant Dry Photograde Paper Glossy) as the base coat. In order to change the concentration of the light-stabilizing additive, the thickness of the applied coating solution was varied. The application was performed by means of a doctor blade coater. The comparative samples were obtained by simply applying the aqueous solution to the recording media without the stabilizing agent.

[0096] After the media were allowed to dry at room temperature for 24 hours, color patches with 50% and 100% ink of cyan, magenta, yellow and black were printed by mea...

[0097] Two ink jet recording media (invention and comparative) were prepared by coating on a resin-coated paper an ink-receiving layer which composition is shown in table 2. The coating weight of the inorganic pigment was 30.0 g / m2. On top of this layer, a gloss improving layer was coated containing 100 parts of the commercial boehmite DISPERAL HP 14 / 2, from Sasol Co., a 25% dispersion in water, 2 parts of a polyvinyl alcohol from Nippon Goshei Co., 0.2 parts of boric acid and 0.8 parts of cetyl-ammonium bromide. The coating thickness was chosen to achieve a pigment coating weight of 5 g / m2. The invention sample contained 20 parts ST-1 in the top layer, the comparative sample not.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS [0001] This application is a divisional of U.S. patent application Ser. No. 10 / 657,466 which claims the benefit of U.S. Provisional Application No. 60 / 412,837 filed Sep. 23, 2002, which is incorporated by reference. In addition, this application claims the benefit of European Application No. 02102340.3 filed Sep. 11, 2002, which is also incorporated by reference.FIELD OF THE INVENTION [0002] The present invention relates to an ink jet recording material having an improved stabilization of the finished image against color fading due to light. BACKGROUND OF THE INVENTION [0003] In the majority of applications printing proceeds by pressure contact of an ink-laden printing form with an ink-receiving material which is usually plain paper. The most frequently used impact printing technique is known as lithographic printing based on the selective acceptance of oleophilic ink on a suitable receptor. [0004] In recent times however so-called non-...
