OPACIFYING PIGMENT PARTICLE

An opacifying pigment that includes a pigment particle having an average particle diameter of from 0.005 to 5 microns and an index of refraction of at least 1.8 such as, for example TiO2, at least partially encapsulated in polymer is provided. Also provided are processes for forming the encapsulated...

More Information
Summary:An opacifying pigment that includes a pigment particle having an average particle diameter of from 0.005 to 5 microns and an index of refraction of at least 1.8 such as, for example TiO2, at least partially encapsulated in polymer is provided. Also provided are processes for forming the encapsulated pigment particle and compositions including the encapsulated pigment particle. Se proporciona un pigmento opacificante que incluye una partícula de pigmento que tiene un diámetro de partícula promedio de desde 0.005 hasta 5 micras y un índice de refracción de al menos 1.8 tal como por ejemplo TiO2, al menos parcialmente encapsulado en polímero. También se proporcionan procesos para formar la partícula de pigmento encapsulada y composiciones que incluyen la partícula de pigmento encapsulada.
