The present invention provides a transparent or colorless coating comprising a heat responsive material that increases in opacity when exposed to heat. An example of a heat responsive material is an inorganic compound or an organic resin. The present invention further provides a coating composition comprising a carrier and a heat responsive material. The coating can further include additives such as an adhesion promoter, a defoamer, a crosslinking agent, a plasticizer, a humectant, a pH adjuster, a biocide, a co-solvent, a surface tension modifier, and/or a combination thereof. The present invention further provides a method for creating a mark on a substrate comprising providing to the substrate the transparent coating to obtain a coated substrate and exposing a selected area of the coated substrate to heat, e.g., a laser, to create the mark. The present invention further provides substrates suitable for laser marking.

Laser markable coating

The present invention provides a laser markable coating composition comprising a colorant and a polymeric material whose opacity changes substantially irreversibly when exposed to heat. The composition may further include a carrier, an adhesion promoter, an energy transfer agent, an opaque polymeric material, and one or more binder resins. The present invention further provides a heat responsive colorant particle comprising a colorant and a polymeric material whose opacity changes substantially irreversibly when exposed to heat.

Coating composition

Surface treated pigment particles made by contacting a dispersion of pigment particles with a halosilane or organohalosilane, elevating the temperature to form a siloxane on the surface of the particles and recovering the surface treated particles as a presscake or as dry particles.

Method for treating pigment particles to improve dispersibility and

Dry, coated pigment particles are obtained by first suspending uncoated pigment particles in an appropriate medium and then coating the particles while in suspension, with a polymer that is at or above the softening point for that polymer. Coating of the pigment particles is achieved by allowing the suspension to cool to a temperature below the solidification temperature for the polymer. The coated pigment particles are then recovered.

Method of making dry pigment surface modified with polyethylene coating

A method for making coated pigment particles by forming a suspension of the desired pigment particles in a medium that also comprises a polymer characterized by having hydrophobic moieties on the polymer backbone and ionic moieties that are present on, or can be formed on a polymer side chain or at the polymer terminals; allowing the suspension of pigment particles to contact said polymer at a temperature above the softening point of the polymer, allowing the resultant suspension to cool to a temperature below the solidification temperature for the polymer while maintaining the pigment particles in suspension, and, if required, forming the ionic moieties.

Method of making pigment with increased hydrophilic properties

Modified iron-containing pigment particles modified with an encapsulant comprising an alkylphenol and lecithin having an HLB value from about 10 to about 15. The modified iron oxide pigments made using the encapsulant exhibit enhanced dispersibility in solvents over a wide range of polarity.
