Pressure sensitive carbonless imaging system incorporating uncolored ferric organophosphates and uncolored chelates |
| abstract |
Pressure sensitive imaging materials are colorless until pressure addressed, but thereafter provide an intense dark image. The materials comprise white ferric organophosphate, ferric organophosphinate, or ferric organophosphonate and a colorless chelate. The choice of substituents on the chelate nucleus can give images with both good discrimination visually and to near infrared radiation (NIR). |
