Vinyl Acrylics (Roplex) have been around since Rhoman Haas developed them as a base for latex paint. Artists have widely used them from the beginning because of their lack of yellowing with age, and flexibility.

Ink jet Canvas suppliers have been selling products such as Glamour 2 for a premium. Rosco, sells a similar product called vinyl acrylic Glaze

I have been using this product as a water resistant canvas sealer for nearly a year now with excellent results. A 4 month south window test during the Nebraska summer showed no detectable changes in test swatches compared to controls. (HP Z3100 prints) Canvas stayed pliable and no signs of cracking or degradation.
