Permanent indicia can be applied to a surface comprising a composition comprising about 35 to about 75% of a polymeric component having dispersed therein about 25 to about 65% of a filler component comprising: i) about 2 to about 65% of an insoluble, infusible particulate, active filler having a mean particle size less than about 2.5 micron and a surface area greater than about 10 m2/g: and (ii) up to about 63% of an insoluble, infusible, particulate, inert filler. The polymeric component should be polar, e.g. by the use of a polymer containing polar groups or adding a polar additive to the composition. |
