Document Type and Number:
Japanese Patent JP5021893
Kind Code:
B2
Abstract:
A phase change ink composition comprises a phase change ink carrier and a chromogen colorant compound. A phase change ink composition comprises a phase change ink carrier and a chromogen colorant compound of formula (I) or (II). [Image] R 1 - R 4 and R 8 - R 1 0H, alkyl, aryl, arylalkyl, or alkylaryl; R 1+R 2 and R 3+R 4a ring; a and b : 0 - 3; c : 0 - 4; R 5 - R 7aryl, (aryl)alkyl, alkylaryl, halo, ester, amide, sulfone, amine, ammonium, nitrile, nitro, hydroxy, cyano, pyridine, pyridinium, ether, aldehyde, ketone, carbonyl, thiocarbonyl, sulfate, sulfide, sulfoxide, phosphine, phosphonium, phosphate, mercapto, nitroso, acyl, acid anhydride, azide, azo, (iso)cyanato, (iso)thiocyanato, urethane, or urea; Y : O, S, N(R 8), or C(R 9)(R 1 0); Q : COOH or SO 3H; Q ->COO ->, or SO 3 ->; d : 1 - 5; A : an anion; CA : H or a cation associated with all but one of the Q ->. The number of carbon atoms in R 1+R 2+R 3+R 4+R 5+R 6+R 7+R 8+R 9+R 1 0 is at least 16. Provided that: when the colorant compound is a compound of formula (III) - (IV) (where T 1 is COOR 1 2, SO 3R 1 3, C(O)NR 1 4R 1 5, or SO 2R 1 6R 1 7; T 2 is T 1 and SO 3; and R 1 2 - R 1 7 are alkyl, aryl, arylalkyl, or alkylaryl), then 1) either c is 0 - 3 or d is 1 - 4; and 2) either three of R 1 - R 4 are H, only one of R 1 - R 4 is H, R 1 and R 2 both are H, R 3 and R 4 are both H, or R 1 and R 3 are both H and R 2 and R 4 are alkyl or arylalkyl. An independent claim is included for process involving: (a) incorporating into an ink jet printing apparatus a phase change ink composition; (b) melting the ink; and (c) causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate.
