Abstract: A coated paperboard (100) comprising: a base substrate (102) having a brightness of about 65 or less measured using TAPPI T452 and a coating (104) on at least one side of the base substrate, wherein the base substrate comprises: one or more opaque layers (114) including a white filler, wherein the opaque layer covers the base substrate so that visibility of the base substrate through the opaque layer is substantially eliminated; a barrier layer (116) covering the opaque layer; wherein the barrier layer substantially prevents aqueous fluids from contacting the opaque layer, and wherein the coated paperboard has a brightness on the side of the base substrate with the coating of about 65 or more measured using TAPPI T452, and a wet brightness drop, on the side of the base substrate with the coating, of about 30 or less, measured using the wet brightness drop test.

Abstract: A process for preparing a starch dispersion may include combining a feed starch and an aqueous liquid to form a starch slurry. The starch slurry may be subjected to a first degradation treatment to form a first mixture. A temperature of the starch slurry during the first degradation treatment may be less than a gelation temperature. The first mixture may be heated to a temperature between the gelation temperature and a solubilization temperature. The heated first mixture may be subjected to a second degradation treatment to form a second mixture. The second mixture may be sheared to form the starch dispersion.

Abstract: The present invention relates to a starch-based binder for carpet backings and carpets made therewith. The binder comprises water, a polymer and an oligomeric or polymeric starch hydrolysate compound.

Abstract: The present invention refers to polymer latex compositions, such as, for example, styrene-butadiene-based or styrene-acrylate-based latices, prepared with sulfur- and halogen-free chain transfer agents, wherein the sulfur- and halogen-free chain transfer agents are abietic acid-containing rosins, such as abietic acid-containing gum rosin. The polymer latex compositions of the present invention exhibit surprisingly high binding strength despite high gel content, and a balanced application profile of paper gloss, ink gloss and ink set-off properties. The polymer latex compositions of the present invention further exhibit the advantage of being of less odor than typical latex-based paper coating compositions.
