POLYUREA AND POLYUREA EPOXY MICROCAPSULES |
摘要 |
<p>An improved process for the production of microcapsules by the use of hydrogen transfer polymerization in the presence of a mixture of emulsifiers including either an aqueous solution of a sodium salt of naphthalen-sulfonic acid-formaldehyde condensate or diphenyloxide disulfonate with a polyvinyl alcohol. The process is particularly useful for the production of microcapsules containing a colorless dye intermediate used in carbonless copy paper (CCP) applications.</p> |
