Claims20
A method of preparing a multicolor paint composition comprising
- (i) providing a resin composition comprising water, a thickener, a polymeric resin, and a plasticizer;
- (ii) providing a colloid-forming composition comprising water and a gelling agent;
- (iii) providing at least two dispersed pigment compositions, wherein each of the at least two dispersed pigment compositions comprise different pigments,
- (iv) mixing the resin composition, the at least two dispersed pigment compositions, and the colloid-forming composition to form a multicolor paint composition comprising dispersible pigment globules, wherein the multicolor paint composition comprises between about 45% to about 55% of the colloid-forming composition by total weight of the multicolor paint composition;
- between about 12% to about 20% of the resin forming composition by total weight of the multicolor paint composition;
- and between about 25% to about 40% of the at least two dispersed pigment compositions by total weight of the multicolor paint composition;
- and wherein a size of the dispersible pigment globules ranges from about 2.5 mm to about 20 mm.

A method of preparing a multicolor paint composition comprising
- (i) providing a resin composition comprising (a) between about 40% to 50% of water by total weight of the resin composition;
- (b) between about 0.3% to about 1% of a thickener by total weight of the resin composition;
- (c) between about 40% to about 50% of a polymeric resin by total weight of the resin composition;
- (d) between about 2% and about 4% of a plasticizer by total weight of the resin composition;
- and (e) between about 0.3% to about 2% of one or more additives by total weight of the resin composition;
- (ii) providing a colloid-forming composition comprising (a) between about 80% to 95% of water by total weight of the colloid-forming composition;
- (b) between about 4% and about 15% of a gelling agent by total weight of the colloid-forming composition;
- (iii) providing at least two dispersed pigment compositions, the at least two dispersed pigment compositions each comprising different pigments, wherein
- a. a first dispersed pigment composition comprises (a) between about 72% to about 90% of water by total weight of the first dispersed pigment composition;
- (b) between about 3% and about 8% of a gelling agent by total weight of the first dispersed pigment composition;
- (c) between about 0.4% to about 7% of a first pigment by total weight of the first dispersed pigment composition;
- (d) between about 4% to about 8% of an extending agent by total weight of the first dispersed pigment composition;
- (e) between about 0.2% to about 0.5% of a thickener by total weight of the first dispersed pigment composition;
- and (f) between about 0.5% to about 4% by weight of at least one additive by total weight of the first dispersed pigment composition;
- b. wherein a second dispersed pigment composition comprises (a) between about 72% to about 90% of water by total weight of the second dispersed pigment composition;
- (b) between about 3% and about 8% of a colloid-forming agent by total weight of the second dispersed pigment composition;
- (c) between about 0.4% to about 7% of a second pigment by total weight of the second dispersed pigment composition;
- (d) between about 4% to about 8% of an extending agent by total weight of the second dispersed pigment composition;
- (e) between about 0.2% to about 0.5% of a thickener by total weight of the second dispersed pigment composition;
- and (f) between about 0.5% to about 4% by weight of at least one additive by total weight of the second dispersed pigment composition;
- mixing the resin composition, the at least two dispersed pigment compositions, and the colloid-forming composition to form a multicolor paint composition comprising dispersible pigment globules, wherein the multicolor paint composition comprises between about 45% to about 55% of the colloid-forming composition by total weight of the multicolor paint composition;
- between about 12% to about 20% of the resin forming composition by total weight of the multicolor paint composition;
- and between about 25% to about 40% of the at least two dispersed pigment compositions by total weight of the multicolor paint composition;
- and wherein a size of the dispersible pigment globules ranges from about 2.5 mm to about 20 mm.
21 more elements
A method of forming dispersed pigment globules comprising (a) providing a colloid-forming composition comprising water and a gelling agent;
- (b) providing a base color composition, the base color composition comprising water, at least one pigment, an extending agent, and a thickener;
- (c) mixing the colloid-forming composition and the base color composition;
- and (d) passing the mixture of the colloid-forming composition and the base color composition through a sieve, the sieve comprising a series of stacked discs, each disc having a plurality of differently sized mesh openings, wherein a plurality of openings in a top disc are larger than a plurality of openings in a bottom disc.
