ABSTRACT:
A water-based embossing composition for use in chemically embossing a foamable polymeric material having a blowing agent incorporated therein comprising: (A) a film-forming resin dissolved or dispersed in said aqueous composition; (B) a modifier which is effective in modifying the activity of the blowing agent comprising particulate solids which are substantially insoluble and uniformly dispersible in the liquid medium of the embossing composition and which have an average particle size of no greater than about 100 microns, said modifier being present in the composition in an amount of at least about 3 wt. %; and (C) optionally, a colorant or a softening agent for the modifier solids or a mixture thereof.
