Latex complexes as stabilized colorant

摘要

The invention relates to the use of cationic latex particles that can complex with anionic dyes to provide water fastness and further to provide a medium in which inherently unstable anionic dyes can be brought in close proximity with other anionic components, by complexation to cationic latices, in order to stabilize the anionic dyes especially with regard to light and oxidative degradation. In particular this invention will provide for methods of generating waterfast and improved lightfast ink jet images.
