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.
Claims8
A transfer printing sheet comprising a support sheet and adhered to the surface thereof in a predetermined pattern a dried form of a water-based embossing composition having a blowing agent incorporated therein and comprising:
- (A) a film-forming resin dissolved or dispersed in said water-based composition;
- (B) a modifier which is effective in modifying the activity of the blowing agent and which comprises particulate solids which are substantially insoluble and uniformly dispersible in the liquid medium of the 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;
- said support sheet being capable of being stripped from the dried form of the composition.
A transfer printing sheet comprising a support sheet and adhered to the surface thereof in a predetermined pattern a dried form of a water-based embossing composition having a blowing agent incorporated therein and 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 and in the form of fine solid particles of sufficiently small size to permit the modifier to be uniformly dispersed in the composition in an effective amount and in the absence of a material which is effective in solubilizing the modifier, said modifier being present in the composition in an amount of at least about 3 wt. %;
- and
- (C) optionally, a softening agent for the solid particles of modifier in an amount at least sufficient to soften said particles.
