Application 10/501,343
Appellants’ invention is directed to a solid pigment preparation, a process of
producing same, and processes for using such a preparation. The
preparation includes at least one pigment, one or more nonionic surface-
active agents, and one or more anionic surface-active agents, each in a
specified amount. The nonionic additive is based on polyethers. The
anionic surface-active additive is based on sulfonates, sulfates,
polyphosphonates, or phosphates. Claim 1 is illustrative and is reproduced
below:
1. A solid pigment preparation including as essential constituents
(A) from 60 to <90% by weight of at least one pigment,
(B) from 10 to <40% by weight of at least one nomionic surface-
active additive based on polyethers, and
(C) from 0.1 to 10% by weight of at least one anionic surface-active
additive based on sulfonates, sulfates, phosphonates or phosphates,
the sum total of the weight percentages not exceeding 100% by
weight.
