Abstract (en)
This invention relates to a paper product, especially light weight papers, prepared with a structured latex particle having opacity and reinforcing characteristics comprising a core region having a light scattering characteristic and a Tg of 80 DEG C or higher and a shell region of 25 DEG C or lower. The structured latex particle provides opacity to the paper without adversely affecting its mechanical strength.
