UN METODO DE ELIMINAR FORMALDEHIDO LIBRE DE UNA SUSPENSION DE MICROCAPSULAS QUE CONTIENE FORMALDEHIDO |
摘要 |
<p>Free formaldehyde is removed from a formaldehyde-containing suspension of microcapsules by the addition of a compound having a B dicarbonyl group or a cyclic ketone. The thus-treated microcapsules are particularly suitable for the production of self-contained pressure sensitive copying material in which the image-generating reactants are present in a single coating composition.</p> |
