ABSTRACT:
Disclosed is a novel paper sheet adapted for the electrostatographic reproduction of images on both sides thereof. The paper bears a surface sizing material having dispersed therein a plurality of microcapsules comprising water or a hydrated salt encased in an impervious capsule wall of a solid material. As the paper is subjected to the electrostatographic fusing operation, water is released from the microcapsules to replenish that lost due to the heat of fusing. In this manner, the paper can be imaged on its other side without encountering the problems associated with dehydration of the paper.
