[0142] Preparation of unsaturated polyols for the preparation of polyurethanes

[0143] Unsaturated polyol - UP-1 A 250 mL 3-neck round bottom flask was charged with 25.8 g (245 mmol) diethanolamine and 0.25 g (1.22 mmol) sodium methoxide. The flask was equipped with a nitrogen inlet, a rubber septum and a stir bar. The reaction mixture was warmed to 105C to dissolve the sodium methoxide. To the reaction mixture was added 144.2 g (164 mmol) of linseed oil. The reaction temperature was raised to 110C and held for 5 hours. After cooling, 200 ml of dichloromethane (DCM) were added and the organics were washed twice with brine. The organic layer was then dried over sodium sulfate. The solvent was removed in vacuo to yield 150 g of a dark oil. Analysis by gradient polymer elution chromatography using an evaporative light scattering detector yielded approximately 40% monool amide ester, 40% diol amide ester, and 20% raw linseed oil.

Abstract

Aqueous ink jet ink compositions are used for ink jet printing colorless, colored or invisible images on receiver elements. These compositions contain a dispersion of an unsaturated natural oil and a water compatible polyurethane. The unsaturated oil dispersion is prepared from conventional surfactants or a polyurethane dispersing agent. The polyurethane is prepared from unsaturated polyol segments prepared from the unsaturated natural oils. The ink preparations are printed on media treated with agents such as metal ions known to catalyze crosslinking reactions in unsaturated oils. Such compositions are useful in various ink jet printing systems including drop on demand and continuous ink jet printing systems.

Description

field of invention [0001] The present invention relates generally to the field of colored and clear inkjet ink compositions for inkjet printing. In particular, it relates to aqueous inkjet ink compositions and inkjet printing methods and image formation using such compositions. Background of the invention [0002] Inkjet printing is a non-impact method of producing printed images by depositing ink droplets onto an image-recording receptor element on a pixel-by-pixel basis in response to digital signals. [0003] Various methods exist for controlling the deposition of ink droplets on a receptor element to produce the desired inkjet printed image. Inkjet printing systems are generally of two types: drop-on-demand (DOD) printing systems and continuous inkjet (CIJ) printing systems. For DOD printing systems, individual droplets are ejected onto the receiver element as desired. Common methods of controlling ink droplet ejection in DOD printing include thermal bubble formation ...
