Filler for heat-sensitive recording paper and process for producing the same |
| abstract |
Disclosed herein is a filler for heat-sensitive recording paper which comprises amorphous silica obtained by reacting hydrosilicofluoric acid and/or an alkali salt thereof with an alkali (such as ammonia and dimethylamine). The filler has a solid acid strength (pk a ) of +6.8 to 3.3, an oil absorption value of 70 to 200 ml/100 g, a nitrogen adsorption specific surface area of 30 to 350 m²/g (by BET method), and a water vapor adsorption specific surface area of 100 to 300 m²/g (by BET method). |
