Abstract
Abstract An adhesive composition for a heat-releasable ceramic decalcomania is provided, the adhesive composition comprising an acrylic resin, a tackifier for said acrylic resin, which tackifier comprises a polyethylene glycol and/or solid polyoxyalkylene derivatives of propylene glycol or ethylenediamine, and an organic solvent therefor. Preferably, this tackifier is employed in combination with a second tackifier comprising one or more aromatic acid esters of monomeric and polymeric alkyl polyols. A heat-releasable ceramic decalcomania is provided which comprises a backing sheet, optionally a wax-impervious barrier layer disposed on said backing sheet, a wax layer disposed on said backing sheet or barrier layer (where employed), a design receiving support layer disposed on said wax layer, a design layer disposed on said support layer, and an adhesive layer as described above disposed on said design layer. In addition, methods for forming such decalcomania and for decorating ware with such decalcomania are also provided.
