Process for improving coating compositions for paper and paper substitutes by use of poly(hydroxyaldehydocarboxylate) dispersing agent |
摘要 |
A process for improving the processability of a coating composition for paper and paper substitutes in which the composition contains at least one undissolved finely divided inorganic substance, organic substance, or mixture of such substances in a system comprised mainly of water, wherein the process comprises mixing into said system about 0.05 - 5.0 percent by weight of at least one dispersing agent consisting essentially of a polymer derived from specified units containing carboxyl, carboxylate, carbonyl and/or hydroxyl groups. A coating composition is provided.
