Patent ID: 8318652

Claim:
A colored speckle comprising: (a) at least one porous carrier material, wherein the at least one porous carrier material is characterized by having a plurality of pores and is selected from clays, silicas, zeolites, metal oxides, diatomaceous earth, mica, talc, chalk, gypsum-containing compounds, leaded zinc oxide, zinc oxide, zinc sulfide, lithopone, titanium dioxide, calcium sulfate, antimony oxide, magnesium silicate, barytes, basic lead carbonate, calcium carbonate, calcium sulfate, barium sulfate, calcium silicate, silica flatting agents, aluminum silicate, hydrous aluminum silicates, magnesium silicates, calcium metasilicate, sodium-potassium-aluminum silicate, sodium tripolyphosphate, sodium silicate, soda ash-containing compounds, and combinations thereof, (b) a first layer comprising at least one releasing agent selected from magnesium sulfate, sodium sulfate, sodium carbonate, sodium chloride, and mixtures thereof, wherein the releasing agent is in direct contact with at least a portion of the plurality of pores of the at least one porous carrier material, and (c) a second layer comprising from about 0.01% to about 10% by weight of at least one polymeric colorant, wherein the polymeric colorant contains at one chromophore group attached to at least one oligomeric or polymeric chain, wherein the chain has at least three repeating units, and wherein the polymeric colorant is in direct contact with at least a portion of the releasing agent layer.
