Abstract
Abstract A water-soluble dye containing composition which comprises of a dye which is soluble in a water-miscible solvent and is insoluble in water alone, a water-miscible solvent and a water-soluble resin. These compositions may be prepared by first dissolving a dye in a water-miscible solvent and thereafter adding the dye solution to an aqueous solution of a resin. The resulting compositions are useful to color aqueous resin emulsions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
68 words
A water-soluble composition comprising a. 0.01% to 40% of a dye which is soluble in water-miscible solvents and insoluble solely in water; b. 1.0% to 88% of a water-miscible solvent or mixture of solvents which is inert to said dye; c. 0.1% to 89% of a water-soluble resin; d. 10% to 98% water; and optionally, a basic compound to raise the pH of the solution to about 10.
Claim 2
Dependent Claim
68 words
A water-soluble composition comprising a. 0.01% to 40% of a dye which is soluble in water-miscible solvents and insoluble solely in water; b. 1.0% to 88% of a water-miscible solvent or mixture of solvents which is inert to said dye; c. 0.1% to 89% of a water-soluble resin; d. 10% to 98% water; and optionally, a basic compound to raise the pH of the solution to about 10.
