Claims21
A protective laminate for a thermal dye sublimation print containing a binder and dispersed thermally expandable microspheres having on the surface of the microspheres less than 1.8 wt % of inorganic particulates.
A protective laminate containing a binder and dispersed thermally expandable microspheres having on the surface of the microspheres an amount of Si sufficiently low enough to provide a Scum Time greater than 3.
A process for providing expandable microspheres containing silica on the surface thereof having reduced scum-forming properties, comprising reducing the amount of silica on the surface of the expandable microspheres.
