Abstract
A recording material including a support having at least one colored surface and a layer of polymeric material is described. The layer including polymeric particles has a core/shell structure, and the particles are either (i) particles having an outermost polymer shell having a calculated Tg of from 40° C. to 80° C., or (ii) particles having an inner polymer shell having a calculated Tg of from 40° C. to 130° C. and an outer polymer shell having a calculated Tg of from −55° C. to 50° C. The calculated Tg of said outer polymer shell is lower than that of said inner polymer shell, the particles including, when dry, at least one void capable of providing opacity to said layer, and the colored surface has sufficient color density to be visibly contrasting to a surface of the subsequent layer including the polymeric particles disposed thereon.
