摘要:
A pigment particle for use in artist color media comprises a silica containing core particle having pore channels formed therein, at least one colorant present in the pore channels in at least part of the silica particle, and a nonporous silica layer coated over the pore channels. A method of manufacturing colored particles for use in artist color media comprises providing a core silica particle having pore channels formed therein, loading at least one colorant into the pore channels of the particle, and depositing a silica layer over the pore channels using fluorosilicic acid. Another method of manufacturing colored particles for use in artist color media comprises providing a porous silica particle having pore channels formed therein, and depositing a silica layer over the pore channels using a fluorosilicic acid where a colorant is present in the fluorosilicic acid.
