Document Type and Number:
Japanese Patent JP5053476
Kind Code:
B2
Abstract:
Specific core-shell, or latex, binders and additives for use in ink-jet printing ink compositions are provided. One class of specific core/shell binders has the general formula ÄAmBnC'p,FsÜx, where A and B are hydrophobic components in which A exhibits a glass transition temperature Tg between about -150 DEG and +25 DEG C and B exhibits a glass transition temperature greater than 25 DEG C, C' is a component that forms a hydrophilic or water-soluble component in the polymer chain, and has an ionic or non-ionic structure, F contains oxygen-hydrogen functional groups such as aldehydes, carboxylic acids, allyl alcohols, acetals, and hemiacetals, m < 30 wt%, n >40 wt%, p < 30 wt%, and s < 30 wt%, with the total of m + n + p + s = 100 wt%, and x = 1 to 100,000. The molecular weight (weight average) of the polymer is between about 1,000 and 2,000,000. The polymers useful in the practice of the invention are prepared by emulsifying the monomers and then conducting a free-radical polymerization in water. The foregoing binder polymer is used in conjunction with amine-containing additives comprising either (a) amine alcohols having the general formula where R1 and R2 are independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, and phenoxy, R is alkyl, X is selected from the group consisting of hydrogen, alkyl, aryl, -OH, -COOH, -CHO, and substituted groups; (b) amines, or (c) polyamines. In the ink compositions of the present invention, the ratio of binder (I) to colorant (pigment) is greater than 1 to 10. The concentration of the amine-containing additive in the ink is within the range of 0.01 to 10 wt%.
