Maintenance Liquid And Method Of Maintenance - A simplified explanation of the abstract

This abstract first appeared for US patent application 18612098 titled 'Maintenance Liquid And Method Of Maintenance

The abstract describes an aqueous maintenance liquid for use in maintaining an ink jet recording apparatus that ejects an aqueous ink composition containing a coloring material. The maintenance liquid includes an organic amine and an organic solvent with Polyol A, which has a normal boiling point of 250°C or lower. The content of Polyol A is over 20.0% by mass, the organic amine content is at least 0.3% by mass, and the total organic solvent content is less than 30.0% by mass. The organic solvent does not contain Polyol B with a normal boiling point higher than 250°C in an amount greater than 1.0% by mass.

Original Abstract Submitted

Provided is an aqueous maintenance liquid for use in maintenance of an ink jet recording apparatus ejecting an ink composition. The ink composition is an aqueous ink composition containing a coloring material. The maintenance liquid contains an organic amine and an organic solvent other than the organic amine. The organic solvent contains Polyol A with a normal boiling point of 250° C. or lower. The content of Polyol A is greater than 20.0% by mass with respect to the total amount of the maintenance liquid. The content of the organic amine is 0.3% by mass or more with respect to the total amount of the maintenance liquid. The total content of the organic solvent is less than 30.0% by mass with respect to the total amount of the maintenance liquid. The organic solvent does not contain Polyol B with a normal boiling point of higher than 250° C. in an amount of greater than 1.0% by mass with respect to the total amount of the maintenance liquid.
