Abstract
Ink composition resistant to bleed in detergents as well as fats and oils is prepared by blending ink concentrate and ink vehicle. Ink concentrate is prepared from organic solvent, basic dye, acidic laking resin, sodium benzoate and surfactant; whereas ink vehicle is made from acrylic binder resin, water, solvent, ammonium hydroxide, cross-linking agent, sulfonated sulfone binder resin, defoamer and buffer.

Ink composition for printing on paper toweling products which is resistant to ink transfer and has pH of 8.1 to 8.5 and viscosity of 10 to 30 seconds in #2 Zahn cup consisting essentially of an ink concentrate dispersed in an ink vehicle, the ink concentrate is prepared from components consisting essentially of the following in amounts specified on weight percent basis:
- 69.20--Organic solvent miscible with water;
- 8.10--basic dye selected from the group consisting of xanthene dyes, diphenyl dyes, diphenyl methane dyes, triaryl methane dyes and mixtures thereof;
- 3.25--sodium benzoate;
- 16.20--acidic laking resin selected from the group consisting of phenolic resins, styrene-acrylic-maleic resins and mistures thereof;
- and
- 3.25--nonionic surfactant;
- and the ink vehicle is prepared from components consisting essentially of the following in amounts specified on weight percent basis:
- 14.25--acrylic binder resin selected from the group consisting of polymers of C.sub.1 to C.sub.4 alkyl acrylates and/or methacrylates with acrylic or methacrylic acid where the acid is in a minor proportion to the total amount of acrylates and methacrylates;
- 7.35--water;
- 11.60--C.sub.2 to C.sub.10 alkanol solvent;
- 0.70--28% ammonium hydroxide;
- 23.00--divalent or trivalent metal salt of fumaric acid adduct of rosin;
- 41.00--sulfonated sulfone anionic binder resin;
- 0.10--silicone defoamer;
- 2.
An ink composition for printing on paper products having viscosity of 10 to 30 seconds in #2 zahn cup which is resistant to ink transfer and has pH of about 8 to 9 comprising an ink vehicle and an ink concentrate dispersed therein, the ink concentrate is prepared by mixing the following components in amounts specified on weight percent basis:
- 55-85 organic solvent miscible with water;
- 3-15 basic dye selected from the group consisting of xanthene dyes, diphenyl dyes, diphenyl methane dyes, triaryl methane dyes and mixtures thereof;
- 0.5-10 benzoic acid or alkali metal salt thereof;
- 2-50 acidic laking resin selected from the group consisting of phenolic resins, styrene-acrylic-maleic resins and mixtures thereof;
- 0.5-10 nonionic surfactant;
- and the ink vehicle is prepared by mixing the following components in amounts specified on weight percent basis;
- 5-30 acrylic binder resin selected from the group consisting of polymers of C.sub.1 to C.sub.4 alkyl acrylates and/or methacrylates with acrylic or methacrylic acid where the acid is in a minor proportion to the total amount of acrylates and methacrylates;
- 1-15 water;
- - 25C.sub.2 to C.sub.10 alkanol;
- 0.05-2 base selected from the group consisting of ammonium hydroxide, morpholine, C.sub.2 to C.sub.6 alkanol amines, and mixtures thereof;
- 10-40 divalent or trivalent metal salt of an unsaturate aliphatic acid adduct of rosin;
- 20-60 sulfonated sulfonic anionic binder resin;
- 0.01-1 defoamer;
- 0.1-10 buffer selected from the group consisting of morpholine, C.sub.2 to C.sub.6 alkanol amines and mixtures thereof.
