Stationery in general includes all items needed for writing. Typical applications are writing utensils for everyday use like fountain pens, ballpoint pens, pencils, felt-tip pens and fineliner pens. Other items are more likely to be found in offices, such as highlighters, whiteboard markers, permanent and non-permanent markers, and stamp-pads. Many quality requirements for stationery colorants are very similar to the ones for inkjet applications and demand similar properties and quality standards. In addition, writing instruments and stamp-pads need to display special features for special ink systems such as document proof inks, invisible inks and erasable inks. Specific requirements are:
● high color strength, especially for black and blue inks
● worldwide compliance with regulations for environmentally safe products, and absence of sensitive by-products
● high surface tension and low viscosity for consistent ink flow
