Abstract

A mineral composition that contains at least about 90 weight percent of headlap granules, at least about 50 weight percent of calcium carbonate, and from about 0.1 to about 1.0 weight percent of a pigmented material. The pigmented material contains from about 10 to about 35 weight percent of pigment and from about 90 to about 65 weight percent of a resin. The mineral composition has superior adhesion properties; when it is tested in accordance with ASTM Standard Test D 4977-03, it loses less than 5 grams of material.

Claims

exact text as granted — not AI-modified
1 . A mineral composition comprised of at least about 90 weight percent of headlap granules, at least about 50 weight percent of calcium carbonate, and from about 0.1 to about 1.0 weight percent of a pigmented material, wherein said pigmented material is comprised of from about 10 to about 35 weight percent of pigment and from about 90 to about 65 weight percent of a resin, and wherein said mineral composition, when tested in accordance with by ASTM Standard Test D 4977-03, loses less than 5 grams of material.  
   
   
       2 . The mineral composition as recited in  claim 1 , wherein said pigmented composition is disposed on said headlap as a coating.  
   
   
       3 . The mineral composition as recited in  claim 2 , wherein said pigment has a particle size distribution such that at least about 95 weight percent of its particles are smaller than about 1 micron.  
   
   
       4 . The mineral composition as recited in  claim 2 , wherein said pigment has a particle size distribution such that at least about 95 weight percent of its particles are within the range of from about 0.1 to about 0.7 microns.  
   
   
       5 . The mineral composition as recited in  claim 4 , wherein said pigment is an inorganic pigment.  
   
   
       6 . The mineral composition as recited in  claim 4 , wherein said pigment is carbon black.  
   
   
       7 . The mineral composition as recited in  claim 6 , wherein said resin is a synthetic resin.  
   
   
       8 . The mineral composition as recited in  claim 7 , wherein said pigmented material is comprised of from about 10 to about 20 weight percent of said carbon black.  
   
   
       9 . The mineral composition as recited in  claim 8 , wherein said synthetic resin is an ester of pentaerythritol and rosin.  
   
   
       10 . The mineral composition as recited in  claim 8 , wherein said mineral composition is comprised of at least about 95 weight percent of said headlap granules.  
   
   
       11 . The mineral composition as recited in  claim 9 , The mineral composition as recited in  claim 2 , wherein said mineral composition is comprised of at least about 80 weight percent of calcium carbonate.  
   
   
       12 . The mineral composition as recited in  claim 11 , wherein at least about 60 weight percent of said headlap granules have sizes in the range of from about 600 to about 1400 microns.  
   
   
       13 . The mineral composition as recited in  claim 12 , wherein at least about 80 weight percent of said headlap granules have sizes in the range of from about 600 to about 1400 microns.  
   
   
       14 . The mineral composition as recited in  claim 12 , wherein less than about 4 weight percent of said headlap granules are smaller than 250 microns.  
   
   
       15 . The mineral composition as recited in  claim 12 , wherein less than about 1 percent of said headlap granules are smaller than 250 microns.  
   
   
       16 . The mineral composition as recited in  claim 14 , wherein said headlap granules are comprised of at least 95 weight percent of particles smaller than 3,350 microns.  
   
   
       17 . The mineral composition as recited in  claim 14 , wherein said headlap granules are comprised of at least 95 weight percent of particles smaller than 1700 microns.  
   
   
       18 . The mineral composition as recited in  claim 16 , wherein said headlap granules are comprised of at least 60 weight percent of particles smaller than 1,000 microns.  
   
   
       19 . The mineral composition as recited in  claim 18 , wherein said headlap granules are comprised of at least 30 weight percent of particles smaller than 850 microns.  
   
   
       20 . The mineral composition as recited in  claim 19 , wherein said headlap granules are comprised of at least 3 weight percent of particles smaller than 600 microns.  
   
   
       21 . The mineral composition as recited in  claim 9 , wherein said headlap granules are comprised of an antistrip agent.  
   
   
       22 . The mineral composition as recited in  claim 9 , wherein said headlap granules are coated with antistrip agent.  
   
   
       23 . The mineral composition as recited in  claim 22 , wherein said coating has a thickness of from about 200 to about 2000 nanometers.  
   
   
       24 . The mineral composition as recited in  claim 22 , wherein said antistrip agent is an amine antistrip agent.  
   
   
       25 . The mineral composition as recited in  claim 24 , wherein said antistrip agent is comprised of an amido-amine.
