The canvas is a polyester/cotton and has an expected life measured in probable centuries. It is acid-free and archival in quality which is a vast improvement over 100% cotton. The ink life is measured in decades. University level studies using various means of accelerating aging puts the normal expectancy of light-fastness at a minimum of 95 years for full color. For black and white 200 years. (And some tests show more like 120 years faithful color.)
The addition of a sprayed coating containing U.V. filters enhances the longevity beyond the recommended minimum 95 years (under controlled lighting and moisture conditions).
