摘要:
Described herein is an article having a microsphere layer comprising a monolayer of microspheres, the monolayer of microspheres comprising a first area substantially free of microspheres and a second area comprising a plurality of randomly-distributed microspheres, wherein the monolayer of microspheres comprises a predetermined pattern, the predetermined pattern comprises at least one of (i) a plurality of the first areas, (ii) a plurality of the second areas, and (iii) combinations thereof; and (b) a bead bonding layer disposed on the microsphere layer, wherein the plurality of microspheres are partially embedded in a first major surface of the bead bonding layer, wherein the article has a retroreflectivity (R a ) of less than 5.0 candelas/lux/square meter. Also disclosed herein are transfer carriers and methods of making the articles and transfer carriers.
