Ink jet recording method operating with a chemically reactive ink.

摘要

An ink jet recording method comprising the steps of : (1) image-wise projecting liquid, called ink, in the form of droplets onto a receiving material containing a substance that by chemically reacting with another substance contained in said droplets is capable of forming a visually detectable product, characterized in that according to a first mode said receiving material contains at least one substantially light-insensitive organic silver salt and said ink contains a reducing agent for said silver salt, and according to a second mode said receiving material contains said reducing agent and the ink contains said silver salt, and optionally (2) heating said receiving material during and/or after the deposition of said ink on said receiving material to start or enhance reduction of said silver salt(s) forming thereby image-wise a deposit of silver metal in said receiving material.
