Definitions

  • the present invention relates to an ink jet recording material having an improved stabilization of the finished image against color fading due to light.
  • ink jet printing has become a technology of choice.
  • a recent survey on progress and trends in ink jet printing technology is given by Hue P. Le in Journal of Imaging Science and Technology Vol. 42 (1), Jan/Febr 1998.
  • tiny drops of ink fluid are projected directly onto an ink receptor surface without physical contact between the printing device and the receptor.
  • the printing device stores the printing data electronically and controls a mechanism for ejecting the drops image-wise. Printing is accomplished by moving the print head across the paper or vice versa.
  • Early patents on ink jet printers include US 3,739,393, US 3,805,273 and US 3,891,121.
  • the jetting of the ink droplets can be performed in several different ways.
  • a continuous droplet stream is created by applying a pressure wave pattern. This process is known as continuous ink jet printing.
  • the droplet stream is divided into droplets that are electrostatically charged, deflected and recollected, and into droplets that remain uncharged, continue their way undeflected, and form the image.
  • the charged deflected stream forms the image and the uncharged undeflected jet is recollected.
  • several jets are deflected to a different degree and thus record the image (multideflection system).
  • the ink droplets can be created “on demand” (“DOD” or “drop on demand” method) whereby the printing device ejects the droplets only when they are used in imaging on a receiver thereby avoiding the complexity of drop charging, deflection hardware, and ink recollection.
  • DOD on demand
  • the ink droplet can be formed by means of a pressure wave created by a mechanical motion of a piezoelectric transducer (so-called “piezo method”), or by means of discrete thermal pushes (so-called “bubble jet” method, or “thermal jet” method).
  • Ink compositions for ink jet typically include following ingredients : dyes or pigments, water and/or organic solvents, humectants such as glycols, detergents, thickeners, polymeric binders, preservatives, etc.. It will be readily understood that the optimal composition of such an ink is dependent on the ink jetting method used and on the nature of the substrate to be printed.
  • the ink compositions can be roughly divided in :
  • 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").
  • the light fading of colorants is mainly due to an oxidative decomposition of the colorant catalyzed by light, in particular by the UV spectral part. Therefore, there is a permanent need of more effective compounds which stabilize the colorants of the ink jet image against fading by light (in short, better "light-stabilizers” or better "antioxidants”).
  • the present invention seeks to realize an improvement in light-fastness of the colorants of the finished image obtained by ink jet printing.
  • an ink jet recording material comprising a support and a porous ink receiving layer comprising a binder, a pigment and a compound according to following general formula (I) : wherein R 1 represents a hydrogen atom, a hydroxyl group, an oxyradical group, an aliphatic group, an acyl group, an aliphatic oxy group or an acyloxy group; and R 2 represents an aliphatic group having at least three carbon atoms and at least two hydroxyl groups.
  • the support for use in the present invention can be chosen from paper type and polymeric type supports well-known from photographic technology.
  • Paper types include plain paper, cast coated paper, polyethylene coated paper and polypropylene coated paper.
  • Polymeric supports include cellulose acetate propionate or cellulose acetate butyrate, polyesters such as polyethylene terephthalate and polyethylene naphthalate, polyamides, polycarbonates, polyimides, polyolefins, poly(vinylacetals), polyethers and polysulfonamides.
  • Other examples of useful high-quality polymeric supports for the present invention include opaque white polyesters and extrusion blends of polyethylene terephthalate and polypropylene. Polyester film supports and especially polyethylene terephthalate are preferred because of their excellent properties of dimensional stability.
  • a subbing layer may be employed to improve the bonding of the ink-receiving layer to the support.
  • Useful subbing layers for this purpose are well known in the photographic art and include, for example, polymers of vinylidene chloride such as vinylidene chloride /acrylonitrile /acrylic acid terpolymers or vinylidene chloride /methyl acrylate /itaconic acid terpolymers.
  • the porous ink receiving layer contains, apart from a binder and a pigment, a light-stabilizer according to general formula (I) as shown above.
  • the 4-acylamino-2,2,6,6-tetramethylpiperazine derivatives according to this general formula (I) are known from US 6,232,469. However, their particular advantage as light-stabilizers in a particular type of ink jet recording material was not recognized in the latter disclosure.

  • the light-stabilizers are preferably added to the coating solution of the ink receiving layer as aqueous solutions.
