Titanium dioxide aqueous dispersion and method for producing same
Provided are a titanium dioxide aqueous dispersion having high dispersibility and little aggregation or coarse particles, and a method for producing the same. The titanium dioxide aqueous dispersion contains titanium dioxide particles having a hydrophobic compound such as a higher fatty acid or a salt thereof on the surface, an aqueous dispersion medium, a nonionic surfactant having an HLB value of 10 or higher, and a basic compound such as an alkanolamine, and the pH is in the 8.5-13 range. The method for producing a titanium dioxide aqueous dispersion has a step for mixing the titanium dioxide particles having a hydrophobic compound on the surface, the aqueous dispersion medium, the nonionic surfactant having an HLB value of 10 or higher, and the basic compound to bring the pH of the aqueous dispersion into the 8.5-13 range.

Dye sublimation ready coating for low temperature plastic substrates
It is the object of the present invention to provide a new polymer coating for low temperature plastics and plastic foams that allows for the application of disperse dyes in a sublimation process that preserves the original properties of the underlying plastic substrate. The composition includes an optically clear synthetic organic polymer base holding two layers, a first reflective layer supported by the low temperature plastic substrate that includes IR radiation reflecting additives, and a second layer supported by the first layer having light scattering particulate additives. The disperse dyes utilized in the invention may include additives to absorb IR radiation provided by an external IR source positioned above the disperse dyes causing the dyes to sublimate and diffuse quickly into the light scattering layer. The combination of these layers allows for diffusion of the disperse dye ink into the light scattering layer while protecting the low temperature plastic below.
