Physical Effects on Image Quality of Inkjet Printing Media; Polymer and Nanopigment Sol

Abstract

When it comes to the quality of inkjet printing image, it has been well known that inkjet receiving media is acting the most important role in the quality of inkjet printing image. Therefore, to get a high quality of inkjet printing image, it is general to use polymer resin as a binder to diffuse some kinds of pigments, silica sol and/or alumina sol, and etc. We used different kind of water-soluble and/or waterdispersible polymers blended with PVA and nano-size silica and alumina sol, which were different in shape and size. From a series of test, observable improvements were obtained in physical properties such as drying time, light stability, water-fastness, glossiness. We discussed the test results.
