Abstract
Provided is an ink jet fluid composition which comprises a liquid carrier medium and one or more chromium complexes of organic acids. Upon ink jet printing on a printing medium and subsequent exposure to an energy source, a durable and water-insoluble layer is formed. Such an ink jet fluid composition and printing process can be advantageously used to produce durable and water-insoluble images on printing media.
Claims10
An ink jet fluid marking material composition comprising a liquid carrier medium and a reactive component, wherein said reactive component comprises one or more chromium complexes of organic acids.
A method for preparing printed images having improved durability and water-insolubility comprising the steps of:
- (a) providing a printing medium comprising a support that bears a receiving layer comprising at least one hydrophilic material;
- (b) providing an ink jet fluid marking material composition comprising a liquid carrier medium and a reactive component, wherein said reactive component comprises one or more chromium complexes of organic acids;
- (c) printing said composition on the receiving layer of the support of said printing medium in a desired imagewise pattern to form a printed medium;
- and
- (d) exposing said printed medium to an energy source that activates said reactive component, thereby forming a durable and water-insoluble layer in said desired imagewise pattern on said printed medium.
A method for printing which comprises providing an ink jet fluid marking material composition comprising a liquid carrier medium and a reactive component, wherein said reactive component comprises one or more chromium complexes of organic acids, in an ink jet printer and applying said composition to a printing medium with the ink jet printer.
