Abstract
Abstract Disintegratable granular pigment composition comprises a pigment and a dispersing agent such as higher fatty acids or metal salts of higher fatty acids. The disintegratable granular pigment composition is prepared by mixing a pigment and a dispersing agent and adding a wetting liquid to form a plastic mixture and granulating the plastic mixture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A process for preparing a disintegratable granular pigment composition which comprises the steps of: (1) forming a plastic but not a fluid mixture by uniformly mixing a mixture which comprises: a pigment; a dispersing agent selected from the group consisting of higher fatty acids and metal salts of higher fatty acids, wherein said dispersing agent is present in an amount of from 0.1 to 5 weight parts per 1 weight part of said pigment; and a wetting liquid which does not appreciably dissolve said dispersing agent, wherein said wetting liquid is present in an amount of from 20 to 150 weight parts per 100 weight parts of said pigment plus said dispersing agent; (2) granulating said plastic mixture to form particles having an average particle diameter of from 0.1 to 5 mm; and (3) drying said particles at a temperature of from 50° to 120° C., wherein the drying temperature is selected to prevent substantial melting of said dispersing agent in the granular product.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
A process according to claim 1 wherein said wetting liquid contains about 0.01 to 10 wt. % of a surfactant.
Claim 4
Dependent Claim
31 words
A process according to claim 1 wherein the granulation is carried out by extruding the plastic mixture through a screen having an average pore diameter of about 0.1 to 5 mm.
Claim 5
Dependent Claim
11 words
The process of claim 1, wherein said wetting liquid is water.
