[0090] 1(a) – Manufacture of polyurethane prepolymers

[0091] Fill 93.55g of Polyol 220-056N (polyether polyol having an average molecular weight of 2000 available from Dow Chemical), 9.55 g of dimethylpropionic acid (DMPA) and 19.11 g of NMP. The mixture was stirred with two PTFE stirrers under 1 mm vacuum. Then, the reactor was purged with nitrogen and heated to 100 °C to produce a clear pale yellow solution. The solution was heated under vacuum for 20 minutes using a dry ice-IPA trap (trap). The vessel was then backflushed with dry nitrogen and cooled to 60°C. Slowly add 21.78 g of TDI using a 60 mL plastic syringe at 59°C (available from Bayer's TD-80). The temperature initially dropped to 57°C, followed by a rapid exotherm requiring cooling air to keep the temperature below 70°C. Then, the remaining TDI was added to the mixture where the temperature was raised to about 73°C. Add 8 drops of tin catalyst (dibutyltin dilaurate) and set the temperature to 80°C. Mix...

Abstract

A composition useful as an inkjet ink is described as well as methods of making the composition. The composition includes a pigment and a polymer and the polymer may include a polyurethane. The composition exhibits properties that make it useful in thermal and piezo inkjet applications.

Description

technical field [0001] The present invention relates to pigment systems, and in particular to pigment systems useful as inkjet inks. Background technique [0002] Inkjet ink compositions generally consist of a vehicle that functions as a carrier, and a colorant such as a dye or pigment. Additives and / or co-solvents may also be introduced to adjust the inkjet ink to achieve the desired overall performance properties. [0003] Generally, individual pigments are not easily dispersed in liquid vehicles. Various techniques have been developed to provide stable pigment dispersions that can be used in inkjet printing. For example, a dispersant may be added to the pigment to improve the dispersibility of the pigment in a particular medium. Examples of dispersants include water-soluble polymers and surfactants. Typically, these polymeric dispersants have a molecular weight of less than 20,000 g / mol in order to maintain solubility and thus pigment stability. [0004] Modified pig...
