A process for producing a polymer of a vinyl ether monomer by contacting the monomer with phosphorous pentoxide as polymerization initiator.

Process for making vinyl ether polymers

What is described herein is a clear white-appearance, water-resistant, color ink-receptive film having a copolymer of (a) vinyl caprolactam and (b) dimethylaminopropyl methacrylamide coated thereon; preferably the weight ratio of (a):(b) is 50-95:50-5; optimally about 80:20. The ink-receptive film of the invention is capable of being printed from a color inkjet printer to form color images thereon which exhibit excellent long-term color stability towards light. These advantageous results are achieved herein while retaining the desired properties of rapid ink dry time, good print quality, highly resolved circular dots, and high, uniform optical density, characteristic of other systems.

Color inkjet receptive films having long term light stability

This invention relates to a composition containing (a) a component selected from the group of a mono- or poly- vinyl substituted mono- or poly-ether, a mono- or poly- vinyl substituted lactam, or a mixture thereof contained in an acidic medium and (b) an aliphatic, primary or secondary mono- or poly-amine at a concentration sufficient to adjust the pH of the composition above
