OPACIFYING POLYMERIC PARTICLE AND USES

摘要

Opacifying and film-forming particles consisting of discrete capsules, each having a solid polymeric shell and a solid polymeric core and having a weight ratio of shell to capsule ranging from 0.25:1 to 0.5:1. The capsules are capable of providing a high degree of opacity and good film integrity in paint compositions in replacement for pigments in binding agents.
