An ink development process for the preparation of pigmented solid inks including the steps of preparing a mill base and preparing an ink from the mill base. The mill base contains a pigment, and a solvent or oil as a wetting and dispersing media for the pigment. The mill base may contain a plasticizer. A hot melt pigmented ink is also provided.
A semi-solid ink composition for marking porous media is described. The ink composition can provide large dot size, low smear, fast drying, and sharp edge definition images when printed on a porous medium, such as a corrugated container. The semi-solid ink composition has the combined properties of both liquid and solid inks.
A compound of formula (1), and compositions containing a plurality of such compounds, wherein, independently at each occurrence, R.sup.1 is a linear alkyl group having at least twenty carbons; R.sup.2 is selected from the diradical that results when two carboxyl groups are removed from polymerized fatty acid, and a linear C.sub.4-12 hydrocarbon group, with the proviso that at least one occurrence of R.sup.2 is the diradical that results when two carboxyl groups are removed from polymerized fatty acid; R.sup.3 is a diradical selected from C.sub.2-36 hydrocarbons and C.sub.4-30 poly(alkyleneoxides); X is selected from O and NH such that X--R.sup.3 --X is selected from O--R.sup.3 --O and NH--R.sup.3 --O; and n represents a number of repeating units selected from 1-5, may be used as a vehicle for hot melt printing inks, including inks for ink jet printing. ##STR1##
A compound of formula (1): ##STR1## wherein, in at least one occurrence, R.sup.1 is an alkyl group having at least seventeen carbons; R.sup.2 includes a polyalkyleneoxide; R.sup.3 includes a C6 carbocyclic group; and n is an integer of at least 1. A process for preparing a compound of the formula (1) comprising combining reactants comprising: (a) a monoacid compound of the formula R.sup.1 --COOH, or a reactive equivalent thereof; (b) a diamine compound of the formula H.sub.2 N--R.sup.2 --NH.sub.2, or a reactive equivalent thereof; and (c) a diacid compound of the formula HOOC--R.sup.3 --COOH, or a reactive equivalent thereof; and heating reactants (a), (b) and (c) at a sufficient temperature, and for a sufficient time, to provide a reaction product that comprises a compound of formula (1). A process of printing, the process including melting a compound of formula (1) and depositing compound of formula (1) onto a substrate.
