Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes.

Abstract: Described are aqueous solutions of materials that can be formed into mechanically robust gels that exhibit reversible LCST behavior. The use of a curable crosslinking agent beneficially allows the LCST materials to be processed as solutions.

Finally, the blending of other formulation components, such as, but not limited to, optical brighteners, dyes, surfactants, and other components is greatly facilitated by the low viscosity nature of the solution.

Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint.
