Abstract: Pigmented latex films were formed from organic pigment phthalocyanine blue and ultrasonic blended latex containing butyl acrylate-styrene copolymer latex(abbreviated as PA+PB)and composite latex prepared via mini-emulsion polymerization(abbreviated as PA/PB)at room temperature respectively and then the films were cured at 120℃.Morphology of pigmented latexes, pigment dispersion in the interior and on the surface of latex films, and color of pigmented latexes were analyzed by DLS, FE-SEM,(Section)-TEM and spectrophotometry.The film formation mechanisms of two kinds of pigmented latexes were studied and compared.It was found that, the binding capacity between pigment and adhesive in blended latex PA+PB were poor.Migration and aggregation of pigment particles would generally occur during film formation, and thus many loose pigment aggregations at micron size could be formed on the surface and in the interior of pigmented latex.In composite latex PA/PB, pigment particles were pre-encapsulated in the interior of quasi-nanoscale adhesive particles.This microcapsule structure led to less obvious effect of pigment particles on film formation.Thus the size of pigment aggregate could be controlled on quasi-nanoscale, and almost all pigment particles could be dispersed in the whole film at the primary particle level.This would give the composite latex PA/PB film better color depth, color fastness and color uniformity.

Key words: latex film, film formation mechanism, dispersion, organic pigment
