Abstract:
A water dispersible phase change ink composition including a hydrophilic wax having at least one ethoxyl moiety; a low viscosity wax having at least one hydroxyl group, wherein the low viscosity wax is miscible with the hydrophilic wax; an optional stabilizer; and a colorant, wherein the colorant is selected to absorb light in a region that one wants to block. An ink jet printer stick or pellet comprising the water dispersible phase change ink composition. A process for forming a photo-imaged stencil using the water dispersible phase change ink composition.
Abstract:
Disclosed is a compound of the formula wherein Ra and Rb each, independently of the other, are hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, R1 and R2 each, independently of the other, are hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, provided that at least one of R1 and R2 is other than hydrogen, and R3, R4, R5, R6, and R7 each, independently of the others, are alkyl, aryl, arylalkyl, alkylaryl, or a substituent other than hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, wherein in each case alkyl, aryl, arylalkyl, or alkylaryl may or may not be substituted and may or may not have hetero atoms therein, and wherein two or more of R3, R4, R5, R6, and R7 can be joined together to form a ring.

Abstract:
A perimidine coupler of formula 1: where R and R′ are substituents independently selected from the group consisting of a hydrogen atom, C1 to C4 alkyl or a solubilizing moiety comprising a substituted or unsubstituted C10 to C70 hydrocarbyl group. At least one of R and R′ is not a hydrogen atom or C1 to C4 alkyl. R″ and R′″ can be independently selected from the group consisting of a hydrogen atom, C1 to C6 alkyl groups and halogens.
