Abstract: The invention relates to an overcoat composition for an imaged image-recording element, the overcoat composition comprising an aqueous carrier, an optional humectant, an optional surfactant, and 0.05 to 20 weight percent, based on the total weight of the overcoat composition, of an addition polymer having an acid number greater than about 110. The invention also relates to a method of making an imaged image recording element having a transparent overcoat, which method comprises forming an image on the image recording element and applying over the image an overcoat composition of the present invention. The overcoat compositions of the invention provide advantageous stain resistance.

Abstract: This invention relates to an ink jet ink composition comprising an aqueous medium and microgel particles, said particles comprising a crosslinked copolymer prepared from a monomer mixture comprising at least a crosslinking monomer, a polymerizable carboxylic acid monomer, and one or more polymerizable water insoluble vinyl type monomers. The ink composition may be a colorless ink or it may contain a colorant.

Abstract: This invention relates to an ink jet ink composition comprising an aqueous medium and at least two different polymers, a first polymer and a second polymer, having a weight average acid number of 70 to 200. In one embodiment the ink is substantially colorless.

Abstract: This invention relates to a substantially colorless ink or overcoat composition comprising an aqueous medium and a polyurethane polymer that has an acid number of 60 to 100 and a weight average molecular weight of greater than 10,000. It particularly relates to an ink jet ink comprising said colorless ink composition.

Abstract: A method of determining and applying a protective ink amount to be printed in addition to a plurality of colored ink amounts to make colored pixels in an image including determining a first protective ink amount responsive to the colored ink amounts, determining multitoned colored ink amounts using a multitone processor responsive to the colored ink amounts, and determining a second protective ink amount responsive to the multitoned colored ink amounts. The method also includes determining the protective ink amount responsive to the first protective ink amount and the second protective ink amount to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.

Abstract: A method of determining and applying a protective ink amount to be printed in addition to a plurality of colored ink amounts to make colored pixels in an image including determining the protective ink amount such that the sum of the protective ink amount and the colored ink amounts is greater than or equal to a minimum ink amount necessary to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.
