Bright pigment dispersion and method for forming multilayer coating film
The problem to be solved by the present invention is to provide an effect pigment dispersion that exhibits excellent water resistance, that can form metallic or pearly luster, and that further exhibits high stability; and to provide a method for forming a multilayer coating film. The present invention provides an effect pigment dispersion that contains water, a wetting agent (A), a flake-effect pigment (B), and a phosphate-group-containing cellulose-based rheology control agent (C). The effect pigment dispersion has a solids content of 0.1 to 10 parts by mass, per 100 parts by mass of all of the components of the effect pigment dispersion; and has a viscosity of 100 to 10000 mPa.Math.sec as measured with a Brookfield viscometer at a rotational speed of 6 revolutions per minute.
PREPARATION OF A COATINGS FORMULATION WITH ALKALI SWELLABLE POLYMER PARTICLES
The present invention relates to a process for preparing a coatings composition with an open time additive comprising the steps of a) contacting an aqueous dispersion of alkali swellable polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L; and b) neutralizing the alkali swellable particles with a non-volatile base after or upon contact with the rheology modifier and the binder to form swelled multi-staged polymer particles; wherein the alkali swellable polymer particles comprise a shell having a T.sub.g of not greater than 25 C. and an acid functionalized core; and wherein the core-to-shell ratio is in the range of from 1:3.2 to 1:10. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.
In another aspect the present invention relates to the preparation of the coatings composition with an open time additive comprising the steps of a) contacting the open time additive with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L, then b) neutralizing the open time additive to form swelled multi-staged polymer particles, wherein the coatings composition with the open time additive exhibits less than a 50% increase in viscosity than the coating composition without the open time additive.
