## Abstract

A new class of compounds, namely diamino alcohols, is described, along with a process for their production and their use as dispersing additives for coating formulations.

## Claims

### Claim 1

An aqueous coating formulation comprising:
(a) 25-99% by weight of an aqueous carrier comprising water and at least one non-halogenated resin;
(b) up to 20% by weight of a pigment;
(c) 0.01 to 5% by weight of a diamino alcohol compound having the formula:
wherein the amine groups are primary amine groups and R is independently hydrogen, alkyl, aryl, or —CH2OH; R1 is independently hydrogen, alkyl, or —CH2OH; alternatively, R and R1 may be linked together to form a cycloalkyl; R2 is phenyl; R3 is independently hydrogen, alkyl, or phenyl or —CH2OH; R4 is independently hydrogen, alkyl, or —CH2OH; and alternatively, R3 and R4 may be linked together to form a cycloalkyl;
wherein all weight percents are based on the total weight of the aqueous coating formulation.

### Claim 2 (depends on 1)

The aqueous coating formulation according to claim 1, wherein said at least one resin is a polymer comprising units derived from at least one monomer selected from the group consisting of: alkyl acrylates, alkyl methacrylates, styrene-butadiene, vinyl esters of an aliphatic acid, acrylic acid esters, methacrylic acid esters of an alcohol and mono- and di-ethylenically unsaturated hydrocarbons.

### Claim 3 (depends on 2)

### Claim 4 (depends on 3)

The aqueous coating formulation according to claim 3, wherein said at least one resin is a polymer further comprising units derived from at least one monomer selected from the group consisting of: mono- and di-ethylenically unsaturated hydrocarbons and aliphatic dienes.

### Claim 5 (depends on 1)

The aqueous coating formulation according to claim 1, wherein said pigment is selected from the group consisting of: titanium dioxide and other titanium pigments, white lead, zinc, oxide, zinc sulfide, barium sulfate, calcium carbonate, lithopone, silica, talc, mica, clays, iron oxide, carbon black, cadmium sulfide, toluidine red, chrome orange, chrome yellow, chrome green.

### Claim 6 (depends on 1)

The aqueous coating formulation according to claim 1, further comprising one or more materials selected from the group consisting of: a coalescing aid, a thickening aid, a dispersing aid, a binder, a rheology modifier, a crosslinking agent, a wetting agent, a defoamer and a biocide.

### Claim 7 (depends on 1)

The aqueous coating formulation according to claim 1, wherein R3 is phenyl.
