Abstract
A thermal receiver for image production. The thermal receiver maintains advantageous properties such as surface tension while being made with chemicals with fewer health, safety, and environmental concerns than previous thermal receivers. This includes the elimination of hazardous catalysts and PFAS/fluorinated surfactants from the composition through the use of silicone compatibilizers and trisiloxane surfactants. The composition has low surface tension within a short time frame after being applied to a surface.
Claims20
A composition for a thermal receiver element, comprising:
- a trisiloxane surfactant comprising at least one of an ethoxylated polydimethylsiloxane, a distillate from a mono-functional trisiloxane intermediate, or a polyether-modified siloxane;
- and
- a silicone compatibilizer comprising at least one of a silicone polyether, a silicone glycol copolymer, an organo-modified silicone that is dispersible in water, a siloxane-based Gemini surfactant, a polyether siloxane copolymer, or a polyether-modified polydimethylsiloxane.
A thermal imaging receiver system, comprising:
- a substrate;
- an image-receiving layer disposed on the substrate, the image-receiving layer comprising:
- a dye-receiving layer (DRL) configured to receive thermally transferred dye from a donor element during thermal imaging, the DRL comprising:
- a silicone compatibilizer;
- and
- a trisiloxane surfactant;
- a receiver overcoat (ROC) layer disposed over the DRL, the ROC layer comprising a polymer binder matrix, the polymer binder matrix comprising at least one of a water-dispersible acrylic polymer, a water-dispersible polyester, or a water-dispersible conductive polymeric material.
