Abstract
This invention relates to an inexpensive, printed paper sheet material which has an appearance closely simulating that of foamed polypropylene. The product is prepared by coating a paper sheet with an overall coating of a pearlescent ink and then overprinting the pearlescent coating with a dilute black ink in a fine mottled pattern.
