    Abstract: This invention relates to papers made with fibrids containing a polymer or copolymer derived from a monomer selected from the group consisting of 4,4′diaminodiphenyl sulfone, 3,3′diaminodiphenyl sulfone, and mixtures thereof. Such papers have high thermal stability and accept ink more readily than papers made solely with aramid fibrids.
