Color developer for pressure-sensitive copying paper |
| abstract |
A color developer for pressure-sensitive copying papers is prepared by mixing a para-substituted difunctional phenol-aldehyde condensate and tri- or higher-functional phenol-aldehyde condensate. The tri- or higher-functional phenol-aldehyde condensate can be modified by a polyvalent metal. |
